Fasting, eating earlier in the day or eating fewer meals – what works best for weight loss?

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/hayley-oneill-1458016">Hayley O'Neill</a>, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a> and <a href="https://theconversation.com/profiles/loai-albarqouni-452476">Loai Albarqouni</a>, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a> Globally, <a href="https://www.who.int/news-room/fact-sheets/detail/obesity-and-overweight">one in eight people</a> are living with obesity. This is an issue because <a href="https://www.aihw.gov.au/reports/risk-factors/risk-factors-to-health/contents/overweight-and-obesity">excess fat</a> <a href="https://pubmed.ncbi.nlm.nih.gov/27423262/">increases the risk</a> of type 2 diabetes, heart disease and certain cancers. <a href="https://pubmed.ncbi.nlm.nih.gov/33393504/">Modifying your diet</a> is important for managing obesity and preventing weight gain. This might include reducing your calorie intake, changing your <a href="https://pubmed.ncbi.nlm.nih.gov/39143663/">eating patterns</a> and prioritising healthy food. But is one formula for weight loss more likely to result in success than another? Our <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC11530941/">new research</a> compared three weight-loss methods, to see if one delivered more weight loss than the others: <ul> <li>altering calorie distribution – eating more calories earlier rather than later in the day</li> <li>eating fewer meals</li> <li>intermittent fasting.</li> </ul> We analysed data from 29 clinical trials involving almost 2,500 people. We found that over 12 weeks or more, the three methods resulted in similar weight loss: 1.4–1.8kg. So if you do want to lose weight, choose a method that works best for you and your lifestyle. <h2>Eating earlier in the day</h2> When our metabolism <a href="https://www.betterhealth.vic.gov.au/health/conditionsandtreatments/metabolic-syndrome">isn’t functioning properly</a>, our body can’t respond to the hormone insulin properly. This can lead to weight gain, fatigue and can increase the risk of a number of chronic diseases such as diabetes. Eating later in the day – with a <a href="https://pubmed.ncbi.nlm.nih.gov/23512957/">heavy dinner</a> and late-night snacking – seems to lead to <a href="https://pubmed.ncbi.nlm.nih.gov/33172509/">worse metabolic function</a>. This means the body becomes less efficient at converting food into energy, managing blood sugar and regulating fat storage. In contrast, consuming calories <a href="https://pubmed.ncbi.nlm.nih.gov/31151228/">earlier</a> in the day appears to <a href="https://pubmed.ncbi.nlm.nih.gov/29754952/">improve</a> metabolic function. However, this might not be the case for everyone. Some people naturally have an evening “chronotype”, meaning they wake up and stay up later. People with this chronotype appear to have <a href="https://pubmed.ncbi.nlm.nih.gov/36803075/">less success losing weight</a>, no matter the method. This is due to a combination of factors including genes, an increased likelihood to have a poorer diet overall and higher levels of hunger hormones. <h2>Eating fewer meals</h2> <a href="https://pubmed.ncbi.nlm.nih.gov/30700403/">Skipping breakfast</a> is common, but does it hinder weight loss? Or is a <a href="https://pubmed.ncbi.nlm.nih.gov/28967343/">larger breakfast and smaller dinner</a> ideal? While <a href="https://pubmed.ncbi.nlm.nih.gov/28137935/">frequent meals</a> may reduce disease risk, recent studies suggest that compared to eating one to two meals a day, eating six times a day might increase <a href="https://pubmed.ncbi.nlm.nih.gov/32437566/">weight loss success</a>. However, this doesn’t reflect the broader research, which tends to show consuming <a href="https://pubmed.ncbi.nlm.nih.gov/33485709/">fewer meals</a> can lead to greater weight loss. <a href="https://pubmed.ncbi.nlm.nih.gov/39485353/">Our research</a> suggests three meals a day is better than six. The easiest way to do this is by cutting out snacks and keeping breakfast, lunch and dinner. Most studies compare three versus six meals, with limited evidence on whether <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC7490164/">two meals is better than three</a>. However, <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC11530941/">front-loading your calories</a> (consuming most of your calories between breakfast and lunch) appears to be better for weight loss and may also help <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC9605877/">reduce hunger</a> across the day. But more studies with a longer duration are needed. <h2>Fasting, or time-restricted eating</h2> Many of us eat over a period of more than <a href="https://pubmed.ncbi.nlm.nih.gov/26411343/">14 hours a day</a>. Eating late at night <a href="https://pubmed.ncbi.nlm.nih.gov/26411343/">can throw off</a> your body’s natural rhythm and alter how your organs function. Over time, this can increase your risk of type 2 diabetes and other chronic diseases, particularly among <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC8617838/">shift workers</a>. <a href="https://pubmed.ncbi.nlm.nih.gov/35194176/">Time-restricted eating</a>, a form of intermittent fasting, means eating all your calories within a <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC7262456/">six- to ten-hour window</a> during the day when you’re most active. It’s not about changing what or how much you eat, but <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC7262456/">when you eat it</a>. <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC7262456/">Animal studies</a> suggest time-restricted eating can lead to weight loss and improved metabolism. But the evidence in humans is still limited, especially about the long-term benefits. It’s also unclear if the benefits of time-restricted eating are due to the timing itself or because people are eating less overall. When we looked at studies where participants ate freely (with no intentional calorie limits) but followed an eight-hour daily eating window, they naturally consumed about 200 fewer calories per day. <h2>What will work for you?</h2> In the past, clinicians have thought about weight loss and avoiding weight gain as a simile equation of calories in and out. But factors such as how we distribute our calories across the day, how often we eat and whether we eat late at night may also impact our metabolism, weight and health. There are no easy ways to lose weight. So choose a method, or combination of methods, that suits you best. You might consider <ul> <li>aiming to eat in an eight-hour window</li> <li>consuming your calories earlier, by focusing on breakfast and lunch</li> <li>opting for three meals a day, instead of six.</li> </ul> The <a href="https://link.springer.com/article/10.1007/s13679-024-00555-2">average adult gains 0.4 to 0.7 kg per year</a>. Improving the quality of your diet is important to prevent this weight gain and the strategies above might also help. Finally, there’s still a lot we don’t know about these eating patterns. Many existing studies are short-term, with small sample sizes and varied methods, making it hard to make direct comparisons. More research is underway, including well-controlled trials with larger samples, diverse populations and consistent methods. So hopefully future research will help us better understand how altering our eating patterns can result in better health.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/242028/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/hayley-oneill-1458016">Hayley O'Neill</a>, Assistant Professor, Faculty of Health Sciences and Medicine, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a> and <a href="https://theconversation.com/profiles/loai-albarqouni-452476">Loai Albarqouni</a>, Assistant Professor | NHMRC Emerging Leadership Fellow, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

For type 2 diabetes, focusing on when you eat – not what – can help control blood sugar

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/evelyn-parr-441878">Evelyn Parr</a>, <a href="https://theconversation.com/institutions/australian-catholic-university-747">Australian Catholic University</a> and <a href="https://theconversation.com/profiles/brooke-devlin-2237174">Brooke Devlin</a>, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a> Type 2 diabetes affects <a href="https://www.aihw.gov.au/reports/diabetes/diabetes/contents/how-common-is-diabetes/type-2-diabetes">1.2 million Australians</a> and accounts for <a href="https://www.diabetesaustralia.com.au/about-diabetes/type-2-diabetes/">85-90%</a> of all diabetes cases. This chronic condition is characterised by high blood glucose (sugar) levels, which carry serious <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(17)30058-2/abstract">health</a> risks. <a href="https://www.nature.com/articles/nrendo.2017.151">Complications</a> include heart disease, kidney failure and vision problems. Diet is an important way people living with type 2 diabetes manage blood glucose, alongside exercise and medication. But while we know individualised, professional dietary advice improves blood glucose, it can be <a href="https://linkinghub.elsevier.com/retrieve/pii/S0168822717317588">complex</a> and is not always <a href="https://www.publish.csiro.au/py/PY13021">accessible</a>. <a href="https://www.sciencedirect.com/science/article/pii/S0168822724008039">Our new study</a> looked at the impact of time-restricted eating – focusing on when you eat, rather than what or how much – on blood glucose levels. We found it had similar results to individualised advice from an accredited practising dietitian. But there were added benefits, because it was simple, achievable, easy to stick to – and motivated people to make other positive changes. <h2>What is time-restricted eating?</h2> Time-restricted eating, also known as <a href="https://www.annualreviews.org/content/journals/10.1146/annurev-nutr-082018-124320">the 16:8 diet</a>, became popular for weight loss around 2015. Studies have since shown it is also an <a href="https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2811116">effective way</a> for people with type 2 diabetes to manage blood glucose. Time-restricted eating involves limiting when you eat each day, rather than focusing on what you eat. You restrict eating to a window during daylight hours, for example between 11am and 7pm, and then fast for the remaining hours. This can sometimes naturally lead to also eating less. Giving your body a break from constantly digesting food in this way helps align eating with natural <a href="https://doi.org/10.1111/jne.12886">circadian rhythms</a>. This <a href="https://doi.org/10.1111/jnc.15246">can help</a> regulate metabolism and improve overall health. For people with type 2 diabetes, there may be specific benefits. They often have their <a href="https://doi.org/10.2337/dc12-2127">highest blood glucose</a> reading in the morning. Delaying breakfast to mid-morning means there is time for physical activity to occur to help reduce glucose levels and prepare the body for the first meal. <h2>How we got here</h2> We ran an <a href="https://www.mdpi.com/2072-6643/12/11/3228">initial study</a> in 2018 to see whether following time-restricted eating was achievable for people with type 2 diabetes. We found participants could easily stick to this eating pattern over four weeks, for an average of five days a week. Importantly, they also had improvements in blood glucose, spending less time with high levels. <a href="https://www.mdpi.com/2072-6643/12/2/505">Our previous research</a> suggests the reduced time between meals may play a role in how the hormone insulin is able to reduce glucose concentrations. <a href="https://doi.org/10.1001/jamanetworkopen.2023.39337">Other studies</a> have confirmed these findings, which have <a href="https://doi.org/10.1186/s12986-021-00613-9">also shown</a> notable improvements in HbA1c. This is a <a href="https://www.ncbi.nlm.nih.gov/books/NBK304271/">marker</a> in the blood that represents concentrations of blood glucose over an average of three months. It is the <a href="https://journals.sagepub.com/doi/10.4137/BMI.S38440">primary clinical tool</a> used for diabetes. However, these studies provided intensive support to participants through weekly or fortnightly meetings with researchers. While we know this level of support <a href="https://www.nature.com/articles/0802295">increases</a> how likely people are to stick to the plan and improves outcomes, it is not readily available to everyday Australians living with type 2 diabetes. <h2>What we did</h2> In our <a href="https://www.sciencedirect.com/science/article/pii/S0168822724008039">new study</a>, we compared time-restricted eating directly with advice from an <a href="https://dietitiansaustralia.org.au/working-dietetics/standards-and-scope/role-accredited-practising-dietitian">accredited practising dietitian</a>, to test whether results were similar across six months. We recruited 52 people with type 2 diabetes who were currently managing their diabetes with up to two oral medications. There were 22 women and 30 men, aged between 35 and 65. Participants were randomly divided into two groups: diet and time-restricted eating. In both groups, participants received four consultations across the first four months. During the next two months they managed diet alone, without consultation, and we continued to measure the impact on blood glucose. In the diet group, consultations focused on changing their diet to control blood glucose, including improving diet quality (for example, eating more vegetables and limiting alcohol). In the time-restricted eating group, advice focused on how to limit eating to a nine-hour window between 10am and 7pm. Over six months, we measured each participant’s blood glucose levels every two months using the HbA1c test. Each fortnight, we also asked participants about their experience of making dietary changes (to what or when they ate). <h2>What we found</h2> We found time-restricted eating was as effective as the diet intervention. Both groups had reduced blood glucose levels, with the greatest improvements occurring after the first two months. Although it wasn’t an objective of the study, some participants in each group also lost weight (5-10kg). When surveyed, participants in the time-restricted eating group said they had adjusted well and were able to follow the restricted eating window. Many told us they had family support and enjoyed earlier mealtimes together. Some also found they slept better. After two months, people in the time-restricted group were looking for more dietary advice to further improve their health. Those in the diet group were less likely to stick to their plan. Despite similar health outcomes, time-restricted eating seems to be a simpler initial approach than making complex dietary changes. <h2>Is time-restricted eating achievable?</h2> The main barriers to following time-restricted eating are social occasions, caring for others and work schedules. These factors may prevent people eating within the window. However, there are many benefits. The message is simple, focusing on when to eat as the main diet change. This may make time-restricted eating more translatable to people from a wider variety of socio-cultural backgrounds, as the types of foods they eat don’t need to change, just the timing. Many people don’t have access to more individualised support from a dietitian, and receive nutrition advice from their GP. This makes time-restricted eating an alternative – and equally effective – strategy for people with type 2 diabetes. People should still try to stick to <a href="https://www.eatforhealth.gov.au/guidelines/guidelines">dietary guidelines</a> and prioritise vegetables, fruit, wholegrains, lean meat and healthy fats. But our study showed time-restricted eating may also serve as stepping stone for people with type 2 diabetes to take control of their health, as people became more interested in making diet and other positive changes. Time-restricted eating might not be appropriate for everyone, especially people on medications which don’t recommend fasting. Before trying this dietary change, it’s best speak to the healthcare professional who helps you manage diabetes.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/241472/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/evelyn-parr-441878">Evelyn Parr</a>, Research Fellow in Exercise Metabolism and Nutrition, Mary MacKillop Institute for Health Research, <a href="https://theconversation.com/institutions/australian-catholic-university-747">Australian Catholic University</a> and <a href="https://theconversation.com/profiles/brooke-devlin-2237174">Brooke Devlin</a>, Lecturer in Nutrition and Dietetics, School of Human Movement and Nutrition Sciences, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Does eating ham, bacon and beef really increase your risk of developing type 2 diabetes?

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/duane-mellor-136502">Duane Mellor</a>, <a href="https://theconversation.com/institutions/aston-university-1107">Aston University</a> That lunchtime staple, the humble ham sandwich, has come in for a bashing in the press recently. According to <a href="https://www.theguardian.com/society/article/2024/aug/20/two-slices-of-ham-a-day-can-raise-type-2-diabetes-risk-by-15-research-suggests">many</a> <a href="https://www.dailymail.co.uk/health/article-13761253/Eating-ham-daily-linked-increase-risk-diabetes.html">reports</a>, eating two slices of ham a day can increase your risk of developing type 2 diabetes. But what’s the science behind these headlines? The research offers a more complex picture. <a href="https://www.thelancet.com/journals/landia/article/PIIS2213-8587(24)00179-7/fulltext">A new study</a> from the University of Cambridge highlighted an association between developing type 2 diabetes and eating processed meat like ham and bacon, and red meat such as beef and lamb. This led to headlines suggesting the risk was mainly linked to <a href="https://www.telegraph.co.uk/news/2024/08/21/ham-sandwich-processed-meat-fresh-risk-link-type-2-diabetes/">ham sandwiches</a>. This seems to have come from the <a href="https://www.cam.ac.uk/research/news/red-and-processed-meat-consumption-associated-with-higher-type-2-diabetes-risk">press release</a>, which used ham as the example to quantify the amount of processed meat associated with a 15% increased risk of developing type 2 diabetes over ten years. The research found that this risk was linked to eating an extra 50g of processed meat every day, which happens to equate to two slices of ham. A useful example thus appears to have been taken up by the media as the main cause, perhaps ignoring some of the key messages coming from the study. So, can processed and red meat really increase your risk of developing type 2 diabetes? The <a href="https://www.diabetes.org.uk/diabetes-the-basics/types-of-diabetes/type-2/diabetes-risk-factors">biggest risk factors</a> linked to developing type 2 diabetes are being over 40, having family members with type 2 diabetes, being of South Asian or African descent, or having a higher body weight – and especially a larger waist. <figure><iframe src="https://www.youtube.com/embed/EsOBcx2bJqU?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> The Cambridge study used data from nearly 2 million people from 31 studies. Participants were followed for an average of ten years. During this time, around one in 20 people developed type 2 diabetes. The research suggested that a 10% increase in the probability of developing type 2 diabetes was associated with every 100g of additional red meat eaten daily. Eating half as much extra processed meat every day was linked to an even greater increased risk of developing the disease. This is not the <a href="https://ajcn.nutrition.org/article/S0002-9165(23)66119-2/abstract">first time</a> that both processed and red meats have been linked with an increased risk of developing type 2 diabetes. However, the key strength of the Cambridge study was that it tried to control for many of the other factors linked to the disease, including smoking, having a higher body weight, dietary intake and exercise. However, the size of the increased risk is modest, considering few people included in the study ate 50g or more processed meat per day – meaning moderate ham consumption is likely to have <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9908545/">no meaningful effect</a> on your risk. <h2>What’s the link?</h2> Processed meat has been linked to increased risk of type 2 diabetes because of its nitrate and salt content – additives that are used to cure many processed meats. Nitrates and salt in processed meats have also <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6893523/">been linked to</a> an increased risk of developing colon cancer. In fact, the World Health Organization classifies the additives as <a href="https://www.who.int/news-room/questions-and-answers/item/cancer-carcinogenicity-of-the-consumption-of-red-meat-and-processed-meat">group 1 carcinogens</a>, which means they can cause a range of cancers. The mechanism linking processed meat to cancer seems to be similar to how it might be linked to type 2 diabetes. During digestion, processed meat produces <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6294997/">N-nitroso chemicals</a>, which can damage cells. This can lead to inflammation and affects how insulin, the hormone that controls blood glucose (sugar), works. This in turn can lead to <a href="https://www.niddk.nih.gov/health-information/diabetes/overview/what-is-diabetes/prediabetes-insulin-resistance">insulin resistance</a>, when cells in your muscles, fat and liver don’t respond well to insulin and can’t easily take up glucose from your blood. Red meat, meanwhile, is <a href="https://www.healthline.com/nutrition/healthy-iron-rich-foods">rich in iron</a>. Research suggests that people with <a href="https://www.diabetes.org.uk/diabetes-the-basics/related-conditions/haemochromatosis-diabetes#:%7E:text=So%20a%20rise%20of%20iron,GP%20as%20soon%20as%20possible.">high levels of iron</a> are more likely to develop type 2 diabetes. However, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8744124/#:%7E:text=The%20WHO%20has%20recognised%20iron,being%20affected%20with%20this%20condition.">low levels of iron</a> are more of a health concern for the general population. Another potential link regarding red meat could be the way it is cooked. <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5521980/">Previous studies</a> have suggested that charred meat, cooked over an open flame or at high temperature, is also linked to an increased risk of developing <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5911789/">type 2 diabetes</a>. Charring meat leads to formation of toxic chemicals such as <a href="https://www.sciencedirect.com/topics/pharmacology-toxicology-and-pharmaceutical-science/heterocyclic-amine#:%7E:text=Heterocyclic%20amines%20are%20aromatic%20compounds,of%20reactions%20called%20Maillard%20reactions.">heterocyclic aromatic amines</a> and harmful compounds like <a href="https://www.healthline.com/nutrition/advanced-glycation-end-products">advanced glycation end products</a>, both of which have been linked to <a href="https://pubmed.ncbi.nlm.nih.gov/21709297/">insulin resistance and type 2 diabetes</a>. <h2>Bye-bye barbecues and bacon butties?</h2> The key message is reduction, rather than avoidance. The UK government nutritional recommendations offer sound advice: limit your combined intake of red and processed meat to no more than <a href="https://www.nhs.uk/live-well/eat-well/food-types/meat-nutrition/#:%7E:text=Red%20meat%20and%20processed%20meat&text=If%20you%20currently%20eat%20more,%2C%20veal%2C%20venison%20and%20goat.">an average of 70g per day</a>. But these guidelines also suggest that red meat can be a valuable source of iron. So, if you decide to stop eating red meat, you should eat alternative sources of iron such as beans, lentils, dark green vegetables and fortified cereals. This needs to be done as part of a carefully planned diet. Non-meat sources of iron are more difficult for our bodies to absorb so should be eaten with a source of vitamin C, found in green vegetables and citrus fruit. The best advice to reduce your risk of developing type 2 diabetes is to maintain a healthy weight – consider losing weight if you have a higher body weight – and be as physically active as possible. A healthy diet should be based on plenty of vegetables, fruit, beans, peas, lentils, nuts and seeds, along with some wholegrain foods, some dairy products, fish and white meat (or vegetarian alternatives) – plus moderate amounts of red meat and minimal processed meat. This will help reduce your risk of type 2 diabetes, <a href="https://www.bhf.org.uk/informationsupport/support/healthy-living/healthy-eating">heart disease</a>, and <a href="https://www.cancerresearchuk.org/about-cancer/causes-of-cancer/diet-and-cancer/does-having-a-healthy-diet-reduce-my-risk-of-cancer">many cancers</a> – as well being more <a href="https://www.bda.uk.com/static/539e2268-7991-4d24-b9ee867c1b2808fc/a1283104-a0dd-476b-bda723452ae93870/one%20blue%20dot%20reference%20guide.pdf">environmentally sustainable</a>. But if you have a penchant for ham sandwiches, rest assured you can continue to indulge as an occasional treat. It’s your overall lifestyle and diet that really matter for your health and risk of developing type 2 diabetes.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/237346/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/duane-mellor-136502">Duane Mellor</a>, Visiting Academic, Aston Medical School, <a href="https://theconversation.com/institutions/aston-university-1107">Aston University</a> This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Jelena Dokic's candid admission on weight loss

Jelena Dokic has opened up on her 20kg weight loss and her previous struggles with depression and an eating disorder. The former tennis player took to Instagram on Sunday to share before and after shots from her weight loss, taken seven years apart, and her past battles with self-worth. She explained to her followers that her current weight loss was a result of her prioritising her mental health. "This is not about body size but feeling that I am not worthy enough to even live!!! On the left 7 years ago," she said. "Even though I have a bit less weight now on the right, this is not about weight. Because even if I was half the size on the left, I would still feel the same. And how is that? Not worthy enough to even live!!" She explained that in the first photo she was afraid to leave the house and was "broken" from her battle with depression and PTSD. "My face, body language and even clothing on the left says it all. This is how low my self worth was. I was afraid to get out of the house," she shared. "I was not able to look people in the eye, I just wanted to wear black or dark grey and cover myself up. I even remember wishing to somehow fully cover my face and head and could I possibly not even need to go out of the house for the rest of my life." "This was anxiety, depression, debilitating effect of trauma that made me feel I was worthless and not even worthy of living. "This was the result of being put down my whole life especially by people close to me." "The person on the left was broken, shattered, battling anxiety, depression, PTSD, BPD and an eating disorder. At times I hoped I wouldn't wake up so that I don't have to feel like this anymore," she continued. She then explained that she wasn't asking for pity as she didn't want to victimise herself. "I wanted to survive and thrive and I got there." She then shared a few motivating words on courage and resilience, saying: "Fight hard. Every single day, don't give up and no matter how scary it is get outside of your comfort zone. It will get easier and more comfortable to do so." "Keep going after it even when it's scary. Be brave and never give up. The way to start feeling good in your own skin and life is to be who you really are and embrace and love yourself." "Don't be afraid of mistakes and failures, they make you learn and as long as you get back up, that's all that matters." "Don't you ever give up on yourself and your goals. Don't ever be defined by someone else's judgement and comments." She encouraged her followers to stay true to themselves and remember their self-worth. "Be yourself. Being authentic, real and vulnerable is the way to being happy and thriving. You are worthy and never allow anyone to tell you otherwise." Images: Instagram

We reviewed the health habits of centenarians. These 4 things could lead to a longer life

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/zhaoli-dai-keller-1547476">Zhaoli Dai-Keller</a>, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a> and <a href="https://theconversation.com/profiles/perminder-sachdev-46869">Perminder Sachdev</a>, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a> The number of centenarians around the world rose from <a href="https://population.un.org/wpp/Download/Standard/Population/">151,000 in 2000</a> to 573,000 in 2021. People are living longer, and we can expect to see more people reach 100 in the years to come. Centenarians <a href="https://academic.oup.com/biomedgerontology/article/67A/4/395/623695">exemplify successful ageing</a>, often experiencing <a href="https://agmr.hapres.com/htmls/AGMR_1264_Detail.html">fewer chronic diseases</a> and maintaining independence in daily life well into their 90s. While <a href="https://link.springer.com/article/10.1186/s12979-016-0066-z">genetics contribute</a> to longevity, modifiable factors account for more than 60% <a href="https://pubmed.ncbi.nlm.nih.gov/14624729/">of successful aging</a>. But what sort of factors specifically contribute to living to 100? To find out, we reviewed lifestyle and health habits of centenarians and near-centenarians (those aged 95–99) worldwide. Our <a href="https://link.springer.com/article/10.1007/s11357-024-01247-4">recent review</a> included 34 observational studies published since 2000. Here are four key factors we found contribute to extreme longevity. <h2>1. A diverse diet with controlled salt intake</h2> Centenarians and near-centenarians typically had a balanced and diverse diet. We found, on average, they consumed between 57% and 65% of their energy intake from carbohydrates, 12% to 32% from protein, and 27% to 31% from fat. Their diets included staple foods (such as rice and wheat), fruits, vegetables, and protein-rich foods like poultry, fish and legumes, with moderate red meat consumption. This dietary pattern, similar to the <a href="https://pubmed.ncbi.nlm.nih.gov/29852087/">Mediterranean diet</a>, is linked to lower risks of <a href="https://doi.org/10.3390/ijerph14111364">physical function impairment</a> and <a href="https://pubmed.ncbi.nlm.nih.gov/31685303/">death</a>. Most centenarians also preferred a low-salt diet. While only one study in our review measured the mean daily sodium intake, finding 1.6 grams, this was within the <a href="https://www.who.int/data/gho/indicator-metadata-registry/imr-details/3082#:%7E:text=A%20salt%20intake%20of%20less,much%20more%20salt%20than%20recommended">World Health Organization’s</a> recommendation of less than 2g of sodium per day (equivalent to about 5g of salt). The <a href="https://pubmed.ncbi.nlm.nih.gov/20234038/">traditional Okinawan diet</a>, known for its consumption by Japanese centenarians on Okinawa Island, contains an estimated 1.1g of sodium. We found higher salt intake (those who preferred salty food or added extra salt to meals) had a 3.6-fold increased risk of physical function impairment compared to those without a preference for salt. Practically, these findings suggest we should include plenty of wholegrains, root vegetables, beans, legumes, fruits and vegetables in our diet, minimise red meat consumption and opt for lean poultry, fish, and plant-based protein, and monitor salt in our food. <h2>2. Lower medication use</h2> Centenarians are not free from chronic conditions but typically develop them much later than average adults. More than half of the people in our review experienced common issues such as hypertension (high blood pressure), dementia, or cognitive impairment. We found people in our review took an average of 4.6 medications. The most frequently used medications included blood pressure medications and drugs for heart disease. This is similar to the results of <a href="https://doi.org/10.3390/jcm9051563">a large health register-based study</a> in Spain, which found centenarians took an average of 4.9 medications. Non-centenarians in this study took 6.7 medications on average. The fact centenarians appear to take fewer medications may indicate better health with fewer medical conditions. However, data on medication use is often self-reported and so may not be entirely accurate, especially among those with cognitive impairment. <a href="https://www.thelancet.com/journals/lanhl/article/PIIS2666-7568(24)00007-2/fulltext">Polypharmacy</a> is often defined as taking five or more medications simultaneously, and is common in older adults. Inappropriate polypharmacy is associated with <a href="https://www.nia.nih.gov/news/dangers-polypharmacy-and-case-deprescribing-older-adults">increased risks</a> of adverse events such as falls, cognitive impairment and hospitalisation, due to harmful drug interactions. While the type or number of prescribed medications may not be within a patient’s control, it’s important for doctors to <a href="https://link.springer.com/article/10.1186/s12875-017-0642-0">prescribe medications</a> only when necessary, fully inform patients about benefits and risks, and regularly review treatment plans. <h2>3. Getting good sleep</h2> Sleep quality and quantity <a href="https://newsinhealth.nih.gov/2013/04/benefits-slumber">affect</a> the immune system, stress hormones, and cardiometabolic functions such as obesity, high blood pressure, and diabetes. Good <a href="https://academic.oup.com/biomedgerontology/article/74/2/204/4837199">sleep</a> is associated with extended years of good health and reduced risks of chronic diseases. In our review, 68% of the centenarians were satisfied with their sleep quality. In a survey of adults’ sleep satisfaction in 13 countries in 2020, sleep satisfaction ranged from <a href="https://www.statista.com/statistics/1233775/adults-worldwide-satisfied-sleep-country/">29% to 67%</a>. The <a href="https://academic.oup.com/biomedgerontology/article/74/2/204/4837199">optimal sleep duration</a> is between seven and eight hours per night. Tips to <a href="https://www.mayoclinic.org/healthy-lifestyle/adult-health/in-depth/sleep/art-20048379">achieving better sleep</a> include keeping a regular sleep routine, creating a restful environment, exercising regularly and managing stress. <h2>4. Living environment</h2> More than 75% of the centenarians and near-centenarians in our review lived in rural areas. This is a pattern reflected in “<a href="https://www.bluezones.com/">blue zones</a>”, areas known for high concentrations of centenarians, such as Okinawa in Japan, Sardinia in Italy, the Nicoya Peninsula in Costa Rica, and Ikaria in Greece. This may be partly related to the connection between nature and health and wellbeing. For example, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6562165/">exposure to green space</a> has been associated with lower stress, depression, blood pressure, type 2 diabetes and heart disease, potentially increasing <a href="https://doi.org/10.1016/j.envint.2023.107785">life expectancy</a>. <h2>Other important factors</h2> We didn’t look at all lifestyle factors associated with longevity in our review. Research also shows <a href="https://www.sciencedirect.com/science/article/abs/pii/S053155650700143X">not smoking</a>, <a href="https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2802963">avoiding alcohol</a> or drinking moderately, staying <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3618983/">physically active</a> and maintaining <a href="https://doi.org/10.1098/rspb.2019.1991">social connections</a> are important for boosting a person’s chances of living to 100. Of course, adopting the lifestyle changes discussed in this article won’t guarantee you’ll reach the ripe old age of 100. And on the flip side, some centenarians have shared <a href="https://theconversation.com/why-you-should-never-take-nutrition-advice-from-a-centenarian-229159">questionable</a> health habits. But many older adults are seeking to adopt <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9092121/">healthier lifestyles</a> to prevent and manage chronic conditions, while health-care professionals are similarly recognising the value of <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5638636/">lifestyle medicine</a>. The earlier you can adopt positive lifestyle changes and healthier habits, the better placed you’ll be to achieve a long and healthy life. Becoming a centenarian is a lifelong endeavour.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/235100/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/zhaoli-dai-keller-1547476">Zhaoli Dai-Keller</a>, Honorary Senior Lecturer, School of Pharmacy, University of Sydney; Nutritional epidemiologist and Lecturer, School of Population Health, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a> and <a href="https://theconversation.com/profiles/perminder-sachdev-46869">Perminder Sachdev</a>, Scientia Professor of Neuropsychiatry, Centre for Healthy Brain Ageing (CHeBA), School of Psychiatry, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

We know what to eat to stay healthy. So why is it so hard to make the right choices?

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/nina-van-dyke-822557">Nina Van Dyke</a>, <a href="https://theconversation.com/institutions/victoria-university-1175">Victoria University</a> A healthy diet <a href="https://www.who.int/initiatives/behealthy/healthy-diet">protects us</a> against a number of chronic diseases, including heart disease, diabetes and cancer. From early childhood, we receive an abundance of <a href="https://cdn.who.int/media/docs/default-source/healthy-diet/healthy-diet-fact-sheet-394.pdf?sfvrsn=69f1f9a1_2&download=true">information</a> about how we <a href="https://www.eatforhealth.gov.au/guidelines/australian-guide-healthy-eating">should eat</a> to be healthy and reduce our risk of disease. And most people have a <a href="https://link.springer.com/content/pdf/10.1186/1479-5868-11-63.pdf">broad understanding</a> of what healthy eating looks like. But this knowledge <a href="https://www.sciencedirect.com/science/article/pii/S0001209216310584?casa_token=6CZgCmT1RMgAAAAA:sSRsj2o6swVfvoBxMIVrMTxqdczSAiFwfTCYzYQ8U3z4ey_WLQ6knpmk8WRH77zugAS3wEAQrA">doesn’t always result</a> in healthier eating. In our new research, we set out to <a href="https://link.springer.com/content/pdf/10.1186/s12889-024-18432-x.pdf">learn more</a> about why people eat the way they do – and what prevents them from eating better. Lack of time was a major <a href="https://onlinelibrary.wiley.com/doi/pdf/10.1111/obr.12472?casa_token=1D1mi-l0TR0AAAAA:dgebTQx-wgw7jbREfdawxZ5AZSDRztvrt8t1tuKyDy1x2mmXlyLDY8z9NbUf0v4hnh80HY_RbAk08Q">barrier</a> to cooking and eating healthier foods. <h2>How do you decide what to eat?</h2> We spoke with <a href="https://link.springer.com/content/pdf/10.1186/s12889-024-18432-x.pdf">17 adults</a> in a regional centre of Victoria. We chose a regional location because less research <a href="https://link.springer.com/content/pdf/10.1186/s40900-020-0179-6.pdf">has been done</a> with people living outside of metropolitan areas and because rates of obesity and other diet-related health issues are <a href="https://www.aihw.gov.au/reports/rural-remote-australians/rural-and-remote-health">higher</a> in such areas in Australia. Participants included a mix of people, including some who said they were over their “most healthy weight” and some who had previously dieted to lose weight. But all participants were either: <ul> <li>young women aged 18–24 with no children</li> <li>women aged 35–45 with primary school aged children</li> <li>men aged 35–50 living with a partner and with pre- or primary-school aged children.</li> </ul> We selected these groups to target <a href="https://www.sciencedirect.com/science/article/pii/S0022318212803669">ages and life-stages</a> in which shifts in eating behaviours may occur. Previous research has found younger women <a href="https://onlinelibrary.wiley.com/doi/pdf/10.1111/j.1470-6431.2007.00642.x?casa_token=33QKWwhc2ogAAAAA:ZvJ6wfXiRC_6eoqvoxD121JOSKSPmIRHcrdiGl2uHzkq5pY6VVPL6WI2DhmxQ2q9i6bBGvLiFl8afQ">tend to</a> be particularly concerned about appearance rather than healthy eating, while women with children often shift their focus to providing for their family. Men <a href="https://onlinelibrary.wiley.com/doi/pdf/10.1111/obr.12472?casa_token=KakMB6hAOQ0AAAAA:fLnpoxZQiiJIdEkg_TOcCq8hBwZef1iZETZKTiG5W6zW2x_PYzK0oLeOg5F9arKThq9RzMWEi4x4Xw">tend to be less interested</a> in what they eat. We asked participants about how they decided what food to eat, when, and how much, and what prevented them from making healthier choices. <h2>It’s not just about taste and healthiness</h2> We found that, although such decisions were determined in part by taste preferences and health considerations, they were heavily influenced by a host of other factors, many of which are outside the person’s control. These included other household members’ food preferences, family activities, workplace and time constraints, convenience and price. <a href="https://jamanetwork.com/journals/jamainternalmedicine/article-abstract/2767106">Healthy eating</a> means consuming a balanced diet rich in nutrients, including a variety of fruits, vegetables, whole grains, lean proteins and healthy fats, while limiting processed foods, added sugars and excessive salt. Healthy eating also includes how we eat and <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0244292">how we think about</a> food and eating, such as having a positive relationship with food. One 35- to 45-year-old woman, for example, said that time constraints and family preferences made it difficult to prepare healthier food: <blockquote> I love the chance when I can actually get a recipe and get all of the ingredients and make it properly, but that doesn’t happen very often. It’s usually what’s there and what’s quick. And what everyone will eat. </blockquote> One of the 35- to 50-year-old men also noted the extent to which family activities and children’s food preferences dictated meal choices: <blockquote> Well, we have our set days where, like Wednesday nights, we have to have mackie cheese and nuggets, because that’s what the boys want after their swimming lesson. </blockquote> <a href="https://onlinelibrary.wiley.com/doi/pdf/10.1111/joss.12649?casa_token=gsnU9O_G2GQAAAAA:mV2vtHlnEd0jqBGJPFkfml_ecLIDqwSlH5xksSwt4eQb_FP_UShyAKm9sLNnKy6Mkf2q9aKAlDEixA">Research shows</a> that children are often more receptive to new foods than their parents think. However, introducing new dishes takes additional time and planning. An 18- to 24-year-old woman discussed the role of time constraints, her partner’s activities, and price in influencing what and when she eats: <blockquote> My partner plays pool on a Monday and Wednesday night, so we always have tea a lot earlier then and cook the simple things that don’t take as long, so he can have dinner before he goes rather than buying pub meals which cost more money. </blockquote> Despite popular perceptions, healthy diets are not more expensive than unhealthy diets. A <a href="https://preventioncentre.org.au/wp-content/uploads/2017/03/1702_FB_LEE_4p_final_lr.pdf">study</a> comparing current (unhealthy) diets with what the <a href="https://www.health.gov.au/resources/publications/the-australian-dietary-guidelines">Australian Dietary Guidelines</a> recommend people should eat found that the healthy diet was 12–15% cheaper than unhealthy diets for a family of two adults and two children. However, learning and planning to prepare new types of meals <a href="https://www.mdpi.com/2072-6643/12/3/877">takes effort and time</a>. Simply educating people about what they should eat won’t necessarily result in healthier eating. People want to eat healthier, or at least know they should eat healthier, but other things <a href="https://link.springer.com/content/pdf/10.1007/s00394-017-1458-3.pdf">get in the way</a>. A key to improving people’s eating behaviours is to make it easy to eat more healthily. Policy changes to make healthy eating easier could include subsidising healthier foods such as fresh produce, providing incentives for retailers to offer healthy options, and ensuring access to nutritious meals in schools and workplaces. <h2>So how can you make healthier food choices easier?</h2> Here are five tips for making healthy choices easier in your household: <ol> <li> If certain days of the week are particularly busy, with little time to prepare fresh food, plan to cook in bulk on days when you have more time. Store the extra food in the fridge or freezer for quick preparation. </li> <li> If you’re often pressed for time during the day and just grab whatever food is handy, have healthy snacks readily available and accessible. This could mean a fruit bowl in the middle of the kitchen counter, or wholegrain crackers and unsalted nuts within easy reach. </li> <li> Discuss food preferences with your family and come up with some healthy meals everyone likes. For younger children, <a href="https://healthykids.nsw.gov.au/downloads/file/campaignsprograms/NewFoodsFussyEaters.pdf">try serving</a> only a small amount of the new food, and serve new foods alongside foods they already like eating and are familiar with. </li> <li> If you rely a lot on take-away meals or meal delivery services, try making a list ahead of time of restaurants and meals you like that are also healthier. You might consider choosing lean meat, chicken, or fish that has been grilled, baked or poached (rather than fried), and looking for meals with plenty of vegetables or salad. </li> <li> Remember, fruit and vegetables taste better and are often cheaper when they are in season. Frozen or canned vegetables are a <a href="https://www.sbs.com.au/news/article/the-cost-of-fresh-fruit-and-veggies-is-rising-is-canned-or-frozen-produce-just-as-healthy/tzuhnfrnr">healthy and quick alternative</a>.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/231489/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> </li> </ol> <a href="https://theconversation.com/profiles/nina-van-dyke-822557">Nina Van Dyke</a>, Associate Professor and Associate Director, Mitchell Institute, <a href="https://theconversation.com/institutions/victoria-university-1175">Victoria University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Food & Wine

Will watching the Olympic Games make you eat more?

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/birau-mia-1238429">Birau Mia</a>, <a href="https://theconversation.com/institutions/em-lyon-business-school-2363">EM Lyon Business School</a> and <a href="https://theconversation.com/profiles/carolina-o-c-werle-1434243">Carolina O.C. Werle</a>, <a href="https://theconversation.com/institutions/grenoble-ecole-de-management-gem-2181">Grenoble École de Management (GEM)</a> Ever wondered why you reach for a snack after hitting the gym? <a href="https://joe.bioscientifica.com/downloadpdf/view/journals/joe/193/2/1930251.pdf">Research shows</a> that physical exercise often leads to increased food consumption, whether it is treating yourself for a job well done or replenishing the energy you have burned. With countless sports events airing and our screens constantly filled with sports’ competitions, a new question arises: Can watching sports on a screen also influence how much we eat? The answer is yes. <a href="https://www.sciencedirect.com/science/article/pii/S0950329317300915">Our research</a> co-authored with <a href="https://www.linkedin.com/in/jannine-lasaleta-94504987">Jannine Lasaleta</a> reveals that watching sports’ videos can increase candy consumption. But there is more to the story: the difficulty of the sports you are watching plays a crucial role in these effects. <h2>From screens to junk food</h2> We first invited 112 students to the <a href="https://www.grenoble-em.com/campus-gem-labs-grenoble">Grenoble Ecole de Management experimental lab</a> to watch a video and test some candies. Half of the students watched a video with men and women <a href="https://fr.adforum.com/creative-work/ad/player/51706/train-barefoot/nike">playing sports</a>, while the other half watched one <a href="https://www.youtube.com/watch?v=xyqR5yI6boo">without any physical activity</a>. We then gave each student a 70g cup of candy and asked them to judge its quality for three minutes. The students who saw the sports’ video ate more candy than those who saw the one without physical activity. Our initial test thus revealed that watching sports’ videos can boost candy consumption, but here’s the twist: male students indulged in far more candy than female students, so maybe the results were triggered by males’ consumption. Plus, we were still unsure if the type of sport watched affects the candy intake. To learn more, we invited just the female students to watch videos portraying either easy (light running) or difficult-to-perform sports (athletics long jump, gymnastics, baseball, rugby or rock climbing). After, the students were invited to test the same candies as before. Students who watched the <a href="https://www.youtube.com/watch?v=2SMXKGE_u-Y">easy sports video</a> (showing a woman and a man running through different landscapes) ate much more candy (30.1 grams) than those who watched the <a href="https://fr.adforum.com/creative-work/ad/player/51706/train-barefoot/nike">difficult sports video</a> (18 grams). We can thus conclude that the ease or difficulty of the exercise shown significantly impacts candy consumption – watching easy-to-perform sports leads to considerably higher candy intake than watching difficult ones. <h2>Why is this happening?</h2> To explain our findings, we looked at research on <a href="https://academic.oup.com/jcr/article-abstract/32/3/370/1867208">goal motivation</a>. When people feel they are not meeting a goal, they push harder; but once they see progress, they tend to slack off. For example, after a workout, those aiming to stay fit might feel they have made good progress and then ease up on their efforts. This can lead to a drop in motivation to pursue related goals, like healthy eating. <a href="https://psycnet.apa.org/record/2006-09808-003">Research</a> shows that achieving smaller goals (like exercising) can make people feel they have earned a break, which can result in indulging more in food. So completing a workout might make you more likely to reward yourself with extra food than if you had not finished your session. And why are women more susceptible to the phenomenon of eating more candy after watching an easy-to-perform sports video? Simply because it has been long <a href="https://phys.org/news/2005-04-women-weight-men.html">shown</a> that women are more concerned with their weight than men and therefore their dieting goals are more salient. Our research suggests that merely watching sports can lead to a sense of vicarious fulfilment of fitness goals. When people can picture themselves doing the activity they are watching, they feel as though they have already exercised, which can lead to more-indulgent food choices. If they perceive the exercise shown as easy rather than difficult, they can more easily imagine themselves doing it, leading to greater feelings of progress toward their fitness goals. This perceived achievement can make them feel they have earned the right to indulge and influence their search for a reward, often resulting in increased food intake. <h2>So what?</h2> This knowledge can be used by policymakers or marketers who aim to encourage healthful lifestyles. When promoting healthy activities by picturing physical activity that seems too easy, people may feel a greater sense of achievement that could backfire and lead to increased consumption. We suggest showing an easy exercise (like walking or jogging) followed by a tougher one (like sprinting or marathon running) as an alternative solution. This approach can motivate people to start with basic exercises while reminding that there is still a long way to go to reach their fitness goals. This strategy could offer an alternative to promote physical activity without giving a false sense of accomplishment. So what is the takeaway for us? Be mindful of how watching sports can affect our eating habits. If you are aiming to stay on track with your diet, watch more challenging sports – it might just help you resist that extra chocolate bar. Moreover, when setting dieting goals, remind yourself that real progress comes from consistent effort, not just imagining yourself doing a workout. Engage in activities that genuinely challenge you, and pair them with mindful eating habits. This way, you can avoid the trap of feeling the fitness goal to be prematurely accomplished and then overindulging. In conclusion, should you watch the Olympic games if you want to keep up with your diet? Of course, but it might be better to choose the physical activities you find the most difficult to perform – and watch them without moderation.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/231199/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/birau-mia-1238429">Birau Mia</a>, Associate Professor of Marketing, <a href="https://theconversation.com/institutions/em-lyon-business-school-2363">EM Lyon Business School</a> and <a href="https://theconversation.com/profiles/carolina-o-c-werle-1434243">Carolina O.C.

“Grief eats you away”: Prince Harry's candid interview about losing his mother

Prince Harry has spoken candidly about his ongoing struggles with grief following the death of his mother, the late Princess Diana, when he was just 12 years old. Upon his brief return to the UK, the Duke of Sussex opened up in a new interview as part of his role as global ambassador for Armed Forces charity Scotty’s Little Soldiers, who work to support children who have lost parents in the military, admitting that “grief eats you away”. Harry detailed how difficult it was losing his mother at such a young age, admitting he spent nearly two decades “not thinking” about her death and was forced to eventually get help after years of “total chaos”. He added that learning how to celebrate a late loved one is difficult for a child, as it made them “sad”. “But realising if I do talk about it, and I’m celebrating their life, then things become easier,” he said. Harry went on, “You convince yourself that the person you’ve lost wants you, or you need to be sad for as long as possible to prove to them that they are missed … Especially when every defence mechanism in your mind, nervous system and everything else is saying ‘do not go there.” <iframe title="YouTube video player" src="https://www.youtube.com/embed/YY-W6VEXlZM?si=SBQyGGCKAOhELxlv" width="560" height="315" frameborder="0" allowfullscreen="allowfullscreen"></iframe> "But then there’s this realisation of, no, they must want me to be happy”. The 39-year-old royal shared how, after decades of silent mourning, he learned suppressing grief was “in fact not” the best form of coping with loss. “It can be for a period of time,” he went on to say. “But…if you suppress this for too long, you can’t suppress it forever it’s not sustainable and it will east away at you inside." “Once realising that if I do talk about it and I’m celebrating their life then actually things become easier.” Image credits: YouTube

Drinking lots of water may seem like a healthy habit – here’s when and why it can prove toxic

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/adam-taylor-283950">Adam Taylor</a>, <a href="https://theconversation.com/institutions/lancaster-university-1176">Lancaster University</a> In late 2023, actor <a href="https://www.glamour.com/story/brooke-shields-recently-experienced-a-full-blown-seizure-and-bradley-cooper-came-running?utm_source=instagram&utm_medium=social&utm_content=instagram-bio-link&client_service_id=31196&client_service_name=glamour&service_user_id=1.78e+16&supported_service_name=instagram_publishing&utm_brand=glm&utm_social_type=owned">Brooke Shields</a> suffered a seizure after “flooding” her body with water. Shields became dangerously low on sodium while preparing for her show by drinking loads of water. “I flooded my system and I drowned myself,” she would later explain. “And if you don’t have enough sodium in your blood or urine or your body, you can have a seizure.” Shields said she found herself walking around outside for “no reason at all”, wondering: “Why am I out here?” <blockquote> Then I walk into the restaurant and go to the sommelier who had just taken an hour to watch my run through. That’s when everything went black. Then my hands drop to my side and I go headfirst into the wall. </blockquote> Shields added that she was “frothing at the mouth, totally blue, trying to swallow my tongue”. Like Shields, many people may be unaware of the dangers of drinking excessive amounts of water – especially because hydration is so often associated with health benefits. Models and celebrities <a href="https://www.teenvogue.com/story/drinking-water-flawless-skin#:%7E:text=If%20you're%20reading%20a,long%20hours%20at%20a%20time.">often advocate</a> drinking lots of water to help maintain clear, smooth skin. Some <a href="https://www.independent.co.uk/life-style/75-hard-challenge-before-and-after-tiktok-b2382706.html">social media influencers</a> have promoted drinking a gallon of water daily for weight loss. But excessive water consumption can cause <a href="https://patient.info/treatment-medication/hyponatraemia-leaflet">hyponatraemia</a> – a potentially fatal condition of low sodium in the blood. <h2>Worried about hydration levels? Check your urine</h2> The body strictly regulates its water content to maintain the optimum level of <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2323003/">total body water</a> and “osmolality” – the concentration of dissolved particles in your blood. Osmolality increases when you are dehydrated and decreases when you have too much fluid in your blood. Osmolality is monitored by <a href="https://pubmed.ncbi.nlm.nih.gov/9074779/">osmoreceptors</a> that regulate sodium and water balance in the hypothalamus – the part of the brain that controls numerous hormones. These osmoreceptors signal the release of antidiuretic hormone (ADH), which acts on blood vessels and the kidneys to control the amount of water and salt in the body. <figure><iframe src="https://www.youtube.com/embed/Qghf7Y9ILAs?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> In healthy people, the body releases ADH when osmolality becomes high. ADH tells the kidneys to reabsorb water, which makes urine more concentrated. The reabsorbed water dilutes the blood, bringing osmolality back to normal levels. Low blood osmolality suppresses the release of ADH, reducing how much water the kidneys reabsorb. This dilutes your urine, which the body then passes to rid itself of the excess water. Healthy urine should be clear and odourless. Darker, yellower urine with a noticeable odour can indicate dehydration – although medications and certain foods, including <a href="https://pubmed.ncbi.nlm.nih.gov/3433805/">asparagus</a>, can affect urine colour and odour, too. <h2>How much is too much?</h2> Adults should consume <a href="https://www.nhs.uk/live-well/eat-well/food-guidelines-and-food-labels/water-drinks-nutrition/">two-to-three litres per day</a>, of which around 20% comes from food. However, we can lose <a href="https://www.ncbi.nlm.nih.gov/books/NBK236237/">up to ten litres</a> of water through perspiration – so sweating during exercise or in hot weather increases the amount of water we need to replace through drinking. Some medical conditions can cause overhydration. Approximately <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3616165/">one in five</a> schizophrenia patients drink water compulsively, a dangerous condition known as <a href="https://www.theguardian.com/uk-news/2024/apr/15/woman-died-mental-hospital-excessive-water-drinking-inquest#:%7E:text=Woman%20died%20at%20mental%20hospital%20after%20excessive%20water%20drinking%2C%20inquest%20told,-Parents%20of%20Lillian&text=A%20woman%20collapsed%20and%20died,water%2C%20an%20inquest%20has%20heard.">psychogenic polydipsia</a>. One long-term study found that patients with psychogenic polydipsia have a <a href="https://pubmed.ncbi.nlm.nih.gov/18984069/">“74% greater chance</a> of dying before a non-polydipsic patient”. In <a href="https://pubmed.ncbi.nlm.nih.gov/22306188/">some cases</a>, people with <a href="https://psychiatry-psychopharmacology.com/en/childhood-and-adolescence-disorders-psychogenic-polydipsia-in-an-adolescent-with-eating-disorder-a-case-report-132438">anorexia nervosa</a> can also suffer from compulsive water drinking. <figure><iframe src="https://www.youtube.com/embed/ReQew2zcN7c?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> For those suffering from polydipsia, treatment is focused on medication to reduce the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10675986/">urge to drink</a>, as well as <a href="https://www.uptodate.com/contents/overview-of-the-treatment-of-hyponatremia-in-adults/print">increasing sodium levels</a>. This should be done gradually to avoid causing <a href="https://www.ncbi.nlm.nih.gov/books/NBK562251/">myelinolysis</a> – <a href="https://www.ncbi.nlm.nih.gov/books/NBK551697/">neurological damage</a> caused by rapid changes in sodium levels in nerve cells. In rare but often highly publicised cases such as that of <a href="http://news.bbc.co.uk/onthisday/hi/dates/stories/november/13/newsid_2516000/2516593.stm">Leah Betts</a> in 1995, some users of the illegal drug MDMA (also known as <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6119400/">ecstasy)</a> have <a href="https://pubmed.ncbi.nlm.nih.gov/11265566/">died</a> after drinking copious amounts of water to rehydrate after dancing and sweating. The drug <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5008716/">increases body temperature</a>, so users drink water to avoid overheating. Unfortunately, MDMA also triggers the <a href="https://pubmed.ncbi.nlm.nih.gov/12105115/">unnecessary release of ADH</a>, causing water retention. The body becomes unable to rid itself of excess water, which affects its electrolyte levels – causing cells to swell with water. Symptoms of water intoxication start with nausea, vomiting, blurred vision and dizziness. As the condition progresses, sufferers can often display symptoms of <a href="https://www.nhs.uk/mental-health/conditions/psychosis/symptoms/">psychosis</a>, such as inappropriate behaviour, confusion, delusions, disorientation and hallucinations. These symptoms are caused by <a href="https://www.ncbi.nlm.nih.gov/books/NBK470386/">hyponatraemia</a>, where sodium levels are diluted or depleted in blood and the subsequent imbalance of electrolytes affects the nervous system. Water begins to move into the brain causing <a href="https://www.sciencedirect.com/science/article/pii/S1572349604000149">a cerebral oedema</a> – brain swelling because of excessive fluid buildup, which is usually fatal if not treated. A healthy body will tell you when it needs water. If you’re thirsty and your urine is dark with a noticeable odour, then you need to drink more. If you aren’t thirsty and your urine is clear or the colour of light straw, then you’re already doing a good job of hydrating yourself.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/228715/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/adam-taylor-283950">Adam Taylor</a>, Professor and Director of the Clinical Anatomy Learning Centre, <a href="https://theconversation.com/institutions/lancaster-university-1176">Lancaster University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

5 ways your sleep affects what you eat

We know a good night’s sleep is good for us but logging in those hours of sleep can be a difficult task. Without quality shut-eye, our productivity decreases, immune system weakens and even our dietary health is negatively affected. You eat more when you sleep less A Mayo Clinic study comparing the eating habits of people who slept as much as they needed and those who only slept two-thirds of their required rest time for eight days, found the subject who were sleep-deprived ended up eating an average of 549 extra calories each day. You snack more, especially at night A lack of sleep can lead to decrease in physical activity and an increase in snacking behaviour. Such behaviours typically leads to weight gain. You crave extra carbs and fatty foods The foods we’re snacking on aren’t usually the healthy variety. A 2013 study found that when we’re tired we not only crave unhealthy, -carbohydrate, and high-fat foods but we’re less likely to consider the consequences of such food choices over time. Disrupted sleep cycle equal changing eating patterns Your internal clock guides both your sleep patterns and your eating patterns – aka when you feel hungry during the day. A 2011 study found that people who are “late sleepers” tend to delay their meals throughout the day and end up consuming more calories than the average meal. Those late-eating habits affect sleep and perpetuates the cycle. You don’t eat the right foods A 2013 study found that sleep-deprived subjects ate half the fruit and vegetable servings of a normal sleeper. This meant losing key nutrients from their diet, which can lead to dietary imbalances and effect the regular functioning of the body. Image credits: Shutterstock

Want to reduce your dementia risk? Eat these 4 foods, says new study

If you are what you eat, this might make you hungrier for foods that are bright in every sense. Research has shown that living, vibrant foods can slow down aging at a cellular level; while fruit and vegetables in particular have been associated with lower incidence of cognitive decline as individuals age. However, research has been relatively lacking on just how much of these brain-healthy foods you really need and which fruit and vegetables are best for the job. In collaboration with public health experts at Harvard University, medical researchers at China’s Zhejiang University School of Medicine conducted a meta-analysis that’s slated to be published in the June 2024 issue of The Journal of Nutrition, Health, and Aging. They combined data from two large-scale population-representative studies that analysed the diets and cognitive function of more than 10,000 participants ages 55 and older from China and the US. <h2>What daily diets revealed</h2> The data included diet questionnaires that honed in on the average of participants’ total daily intake of several different types of foods, including fruit and vegetables, and also broke them down into sub-types like green leafy vegetables and berries. Over a period of five years, the participants also took part in activities designed to assess their cognitive function and the average rate of cognitive decline. Overall, participants who included the most fruit and vegetables in their daily diets performed best on the brain tests and maintained those results over time. This suggested that both fruit and vegetables had protective elements that slowed cognitive decline. <h2>Vegetables that help protect cognition</h2> Interestingly, certain types of vegetables appeared to be more beneficial than others—say the researchers: “Our findings support the potential beneficial roles of VF, especially cruciferous vegetables, green leafy vegetables, and red and yellow vegetables, in maintaining cognitive function and slowing cognitive decline in middle-aged and older adults.” The researchers pointed to several reasons these particular vegetables might have shown a substantial impact, including anti-inflammatory and antioxidation nutrients like flavonoids and various vitamins or even gut improvements that have been shown to help improve or protect cognition. While beans didn’t figure prominently in both studies, they showed a protective element in the US study, so they are also worth keeping on your plate. (Beans are also thought to be one of the top foods for longevity.) <h2>Fruit that pack a punch</h2> As for fruit, while some didn’t show as much of a protective effect across the board, berries and apples are two examples of fruit that experts have previously said provide major polyphenol and antioxidant effect. Participants whose brains maintained performance were shown to have eaten three or more servings of vegetables and two or more servings of fruit per day. This is on par with the five servings of vegetables and two servings of fruit recommended we eat every day.

Eating some chocolate really might be good for you – here’s what the research says

<a href="https://theconversation.com/profiles/dan-baumgardt-1451396">Dan Baumgardt</a>, <a href="https://theconversation.com/institutions/university-of-bristol-1211">University of Bristol</a> Although it always makes me scoff slightly to see Easter eggs making their first appearance in supermarkets at the end of December, there are few people who aren’t delighted to receive a bit of chocolate every year. It makes sense that too much chocolate would be bad for you because of the high fat and sugar content in most products. But what should we make of common claims that eating some chocolate is actually good for you? Happily, there is a fair amount of evidence that shows, in the right circumstances, chocolate may be both beneficial for your heart and good for your mental state. In fact, chocolate – or more specifically cacao, the raw, unrefined bean – is a medicinal wonder. It contains many different active compounds which can evoke pharmacological effects within the body, like medicines or drugs. Compounds that lead to neurological effects in the brain have to be able to cross the <a href="https://link.springer.com/chapter/10.1007/978-3-642-13443-2_7">blood-brain barrier</a>, the protective shield which prevents harmful substances – like toxins and bacteria – entering the delicate nervous tissue. One of these is the compound <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3672386/">theobromine</a>, which is also found in tea and contributes towards its bitter taste. Tea and chocolate also contain caffeine, which theobromine is related to as part of the purine family of chemicals. These chemicals, among others, contribute to chocolate’s addictive nature. They have the ability to cross the blood-brain barrier, where they can influence the nervous system. They are therefore known as <a href="https://pubmed.ncbi.nlm.nih.gov/15549276/">psychoactive</a> chemicals. <figure><iframe src="https://www.youtube.com/embed/HloqayQdR6M?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> What effects can chocolate have on mood? Well, <a href="https://academic.oup.com/nutritionreviews/article/71/10/665/1931144?login=false">a systematic review</a> looked at a group of studies which examined the feelings and emotions associated with consuming chocolate. Most demonstrated improvements in mood, anxiety, energy and states of arousal. Some noted the feeling of guilt, which is perhaps something we’ve all felt after one too many Dairy Milks. <h2>Health benefits of cocoa</h2> There are other organs, aside from the brain, that might benefit from the medicinal effects of cocoa. For centuries, chocolate has been used as a medicine to treat a <a href="https://pubmed.ncbi.nlm.nih.gov/10917925/">long list of diseases</a> including anaemia, tuberculosis, gout and even low libido. These might be spurious claims but there is evidence to suggest that eating cacao has a positive effect on the cardiovascular system. First, it can prevent <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8068178/">endothelial dysfunction</a>. This is the process through which arteries harden and get laden down with fatty plaques, which can in turn lead to heart attacks and strokes. Eating dark chocolate may also reduce <a href="https://www.sciencedirect.com/science/article/pii/S1537189115001135?via%3Dihub">blood pressure</a>, which is another risk factor for developing arterial disease, and prevent formation of clots which block up blood vessels. <figure><iframe src="https://www.youtube.com/embed/8VUcPCbSSCY?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> Some studies have suggested that dark chocolate might be useful in adjusting ratios of <a href="https://pubmed.ncbi.nlm.nih.gov/20968113/">high-density lipoprotein cholesterol</a>, which can help protect the heart. Others have examined insulin resistance, the phenomenon associated with Type 2 diabetes and weight gain. They suggest that the <a href="https://www.sciencedirect.com/science/article/pii/S0963996900000697#:%7E:text=Cocoa%20is%20rich%20in%20polyphenols%20particularly%20in%20catechins,and%20cocoa%20powder%20have%20been%20published%20only%20recently.">polyphenols</a> – chemical compounds present in plants – found in foodstuffs like chocolate may also lead to <a href="https://pubmed.ncbi.nlm.nih.gov/29993262/">improved control of blood sugars</a>. <h2>Chocolate toxicity</h2> As much as chocolate might be considered a medicine for some, it can be a poison for others. It’s well documented that the ingestion of caffeine and theobromine is highly toxic for domestic animals. Dogs are <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4801869/">particularly affected</a> because of their often voracious appetites and generally unfussy natures. The culprit is often dark chocolate, which can provoke symptoms of agitation, rigid muscles and even seizures. In certain cases, if ingested in high enough quantities, it can lead to comas and abnormal, even fatal heart rhythms. Some of the compounds found in chocolate have also been found to have potentially negative effects in humans. Chocolate is a source of oxalate which, along with calcium, is one of the main components of <a href="https://pubmed.ncbi.nlm.nih.gov/20301742/">kidney stones</a>. Some clinical groups have advised against consuming oxalate rich foods, such as spinach and rhubarb – and chocolate, for those who suffer from recurrent kidney stones. So, what should all this mean for our chocolate consumption habits? Science points in the direction of chocolate that has as high a cocoa solid content as possible, and the minimum of extras. The potentially harmful effects of chocolate are more related to fat and sugar, and may counteract any possible benefits. A daily dose of 20g-30g of plain or dark chocolate with cocoa solids above 70% – rather than milk chocolate, which contains fewer solids and white chocolate, which contains none – could lead to a greater health benefit, as well as a greater high. But whatever chocolate you go for, please don’t share it with the dog.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/226759/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/dan-baumgardt-1451396">Dan Baumgardt</a>, Senior Lecturer, School of Physiology, Pharmacology and Neuroscience, <a href="https://theconversation.com/institutions/university-of-bristol-1211">University of Bristol</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Here’s why having chocolate can make you feel great or a bit sick – plus 4 tips for better eating

<a href="https://theconversation.com/profiles/saman-khalesi-366871">Saman Khalesi</a>, <a href="https://theconversation.com/institutions/cquniversity-australia-2140">CQUniversity Australia</a> Australians are <a href="https://www.retail.org.au/media/sweet-spending-boon-predicted-for-easter-retail">predicted</a> to spend around A$1.7 billion on chocolates, hot cross buns and other special foods this Easter season. Chocolate has a long history of production and consumption. It is made from cacao beans that go through processes including fermentation, drying, roasting and grounding. What is left is a rich and fatty liquor that is pressed to remove the fat (cocoa butter) and the cacao (or “cocoa”) powder which will then be mixed with different ingredients to produce dark, milk, white and other types of chocolates. There are several health benefits and potential problems that come in these sweet chocolatey packages. <h2>The good news</h2> Cacao beans contain <a href="https://foodstruct.com/food/cocoa-bean">minerals</a> like iron, potassium, magnesium, zinc and phosphorus and some vitamins. They are also rich in beneficial chemicals called <a href="https://pubmed.ncbi.nlm.nih.gov/23150750/">polyphenols</a>. These are great antioxidants, with the potential to <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5465250/">improve heart health</a>, increase <a href="https://pubmed.ncbi.nlm.nih.gov/25164923/">nitric oxide</a> (which dilates blood vessels) and <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3488419/">reduce blood pressure</a>, provide food for gut microbiota and <a href="https://www.mdpi.com/2072-6643/12/7/1908">promote gut health</a>, boost the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5465250/">immune system</a> and reduce inflammation. However, the concentration of polyphenols in the chocolate we eat depends largely on the cocoa solid amounts used in the final product. In general terms, the darker the chocolate, the more cocoa solids, minerals and polyphenols it has. For example, dark chocolates may have around <a href="https://www.tandfonline.com/doi/full/10.1080/10942912.2011.614984">seven times more polyphenols</a> compared to white chocolates and <a href="https://www.tandfonline.com/doi/full/10.1080/10942912.2011.614984">three times more polyphenols</a> compared to milk chocolates. <h2>But also some bad news</h2> Unfortunately, the <a href="https://theconversation.com/treat-or-treatment-chocolate-is-good-but-cocoa-is-better-for-your-heart-3084">health benefits of cocoa solids</a> are easily offset by the high sugar and fat content of modern-day chocolates. For example, milk and white chocolate eggs are on average 50% sugar, 40% fat (mostly saturated fats) – which means a lot of added kilojoules (calories). Also, there may be some side effects that come with ingesting chocolate. Cocoa beans include a compound called theobromine. While it has the anti-inflammatory properties responsible for some of the health benefits of chocolate, it is also a mild brain stimulant that acts in a similar way to caffeine. The mood boost it offers may also be partly responsible for how much we <a href="https://www.frontiersin.org/articles/10.3389/fphar.2015.00030/full?crsi=662496658&cicada_org_src=healthwebmagazine.com&cicada_org_mdm=direct">like chocolate</a>. Dark chocolate has higher theobromine compared to milk and white chocolate. But accordingly, overindulging in chocolate (and therefore theobromine) may lead to feeling restless, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3672386/">headaches</a> and nausea. <h2>What else is in your chocolate?</h2> Milk and dairy-based chocolates may also cause stomach upset, abdominal pain and bloating in people with <a href="https://dietitiansaustralia.org.au/health-advice/lactose-intolerance">lactose intolerance</a>. This happens when we don’t produce enough lactase enzymes to digest milk sugar (lactose). People with lactose intolerance can usually tolerate up to 6 grams of lactose without showing symptoms. Milk chocolate can have around <a href="https://www.ncbi.nlm.nih.gov/books/NBK310258/">3 grams of lactose</a> per 40 grams (the size of a standard chocolate bar). So two chocolate bars (or the equivalent in milk chocolate eggs or bunnies) may be enough to cause symptoms. It’s worth noting that lactase enzyme activity dramatically declines as we age, with the highest activity in newborns and children. So lactose sensitivity or intolerance may not be such an issue for your kids and your symptoms may increase over time. Genetics also plays a major role in how sensitive people are to lactose. <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6815241/">Allergic reactions</a> to chocolate are usually due to the added ingredients or cross-contamination with potential allergens such as nuts, milk, soy, and some sweeteners used in the production of chocolate. Symptoms can be mild (acne, rashes and stomach pain) or more severe (swelling of the throat and tongue and shortness of breath).

Kate Winslet reveals secret health battle

Kate Winslet has opened up about a secret health battle that she faced following the success of Titanic in the late 1990s. The British actress shared how the global success of the film propelled her into stardom, which welcomed a whole new level of scrutiny about her image. Now, the 48-year-old has spoken candidly about her battles with an eating disorder during the height of her fame. "I never told anyone about it," Winslet told the <a href="https://www.nytimes.com/2024/03/03/magazine/kate-winslet-the-regime.html" target="_blank" rel="noopener">New York Times</a>. "Because guess what – people in the world around you go: 'Hey, you look great! You lost weight!'" Now, even 26 years after the peak of the attention, Winslet says that "even the compliment about looking good is connected to weight. And that is one thing I will not let people talk about." "If they do, I pull them up straight away." While this is the first time Winslet admitted to having an eating disorder, it is not the first time she has addressed unwelcome comments over her appearance. On a podcast in 2022, the actress said she wished she had hit back at critics of her body at the time instead of remaining silent. "I would have said, 'Don't you dare treat me like this. I'm a young woman, my body is changing, I'm figuring it out, I'm deeply insecure, I'm terrified, don't make this any harder than it already is'," Winslet said on the Happy Sad Confused podcast. She continued, "It can be extremely negative. People are subject to scrutiny that is more than a young, vulnerable person can cope with. But in the film industry, it is really changing." "When I was younger my agent would get calls saying, 'How's her weight?' I kid you not. So it's heartwarming that this has started to change." Image credits: Getty Images

I want to eat healthily. So why do I crave sugar, salt and carbs?

<a href="https://theconversation.com/profiles/hayley-oneill-1458016">Hayley O'Neill</a>, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a> We all want to eat healthily, especially as we reset our health goals at the start of a new year. But sometimes these plans are sabotaged by powerful cravings for sweet, salty or carb-heavy foods. So why do you crave these foods when you’re trying to improve your diet or lose weight? And what can you do about it? There are many reasons for craving specific foods, but let’s focus on four common ones: <h2>1. Blood sugar crashes</h2> Sugar is a key energy source for all animals, and its taste is one of the most basic sensory experiences. Even without specific sweet taste receptors on the tongue, a strong preference for sugar can develop, indicating a mechanism beyond taste alone. Neurons <a href="https://www.nature.com/articles/s41593-021-00982-7">responding to sugar</a> are activated when sugar is delivered to the gut. This can increase appetite and make you want to consume more. Giving into cravings also drives an appetite for more sugar. In the long term, research suggests a high-sugar diet can affect <a href="https://www.bmj.com/content/369/bmj.m2382">mood</a>, digestion and <a href="https://pubmed.ncbi.nlm.nih.gov/33339337/">inflammation</a> in the <a href="https://www.science.org/doi/10.1126/scitranslmed.aay6218?url_ver=Z39.88-2003&rfr_id=ori:rid:crossref.org&rfr_dat=cr_pub%20%200pubmed">gut</a>. While there’s a lot of <a href="https://www.sciencedirect.com/science/article/pii/S0149763402000040?via%3Dihub#aep-section-id23">variation between individuals</a>, regularly eating sugary and high-carb foods can lead to <a href="https://pubmed.ncbi.nlm.nih.gov/30951762/">rapid spikes and crashes</a> in blood sugar levels. When your blood sugar drops, your body can respond by craving quick sources of energy, often in the form of sugar and carbs because these deliver the fastest, most easily accessible form of energy. <h2>2. Drops in dopamine and serotonin</h2> Certain neurotransmitters, such as <a href="https://pubmed.ncbi.nlm.nih.gov/30595479/">dopamine</a>, are involved in the reward and pleasure centres of the brain. Eating sugary and carb-rich foods can trigger the release of dopamine, creating a pleasurable experience and reinforcing the craving. Serotonin, the feel-good hormone, suppresses <a href="https://www.sciencedirect.com/science/article/pii/S1569733910700886">appetite</a>. Natural changes in serotonin can influence daily fluctuations in mood, energy levels and attention. It’s also associated with eating more <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5829131/">carb-rich snacks in the afternoon</a>. <a href="https://pubmed.ncbi.nlm.nih.gov/21985780/">Low carb diets</a> may reduce serotonin and lower mood. However, a recent systematic review suggests little association between these diets and risk for <a href="https://www.sciencedirect.com/science/article/pii/S0165032722013933?via%3Dihub">anxiety and depression</a>. Compared to men, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4189179/">women tend to crave more carb rich foods</a>. Feeling irritable, tired, depressed or experiencing carb cravings are part of premenstrual <a href="https://pubmed.ncbi.nlm.nih.gov/29218451/">symptoms</a> and could be <a href="https://www.ncbi.nlm.nih.gov/books/NBK560698/">linked to</a> reduced <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9928757/">serotonin levels</a>. <h2>3. Loss of fluids and drops in blood sugar and salt</h2> Sometimes our bodies crave the things they’re missing, such as hydration or even salt. A low-carb diet, for example, <a href="https://www.ncbi.nlm.nih.gov/books/NBK537084/">depletes</a> insulin levels, decreasing sodium and water retention. <a href="https://www.sciencedirect.com/science/article/pii/S1933287419302673">Very low-carb diets</a>, like ketogenic diets, induce “ketosis”, a metabolic state where the body switches to using fat as its primary energy source, moving away from the usual dependence on carbohydrates. Ketosis is often associated with increased urine production, further contributing to potential fluid loss, electrolyte imbalances and salt cravings. <h2>4. High levels of stress or emotional turmoil</h2> <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4214609/">Stress</a>, boredom and emotional turmoil can lead to cravings for comfort foods. This is because stress-related hormones can impact our appetite, satiety (feeling full) and food preferences. The stress hormone <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3425607/">cortisol</a>, in particular, can drive cravings for <a href="https://www.sciencedirect.com/science/article/abs/pii/S0306453000000354">sweet comfort foods</a>. A <a href="https://www.sciencedirect.com/science/article/abs/pii/S0306453000000354">2001 study</a> of 59 premenopausal women subjected to stress revealed that the stress led to higher calorie consumption. <a href="https://pubmed.ncbi.nlm.nih.gov/37295418/">A more recent study</a> found chronic stress, when paired with high-calorie diet, increases food intake and a preference for sweet foods. This shows the importance of a healthy diet during stress to prevent weight gain. <h2>What can you do about cravings?</h2> Here are four tips to curb cravings: 1) don’t cut out whole food groups. Aim for a well-balanced diet and make sure you include: <ul> <li> sufficient protein in your meals to help you feel full and reduce the urge to snack on sugary and carb-rich foods. Older adults should aim for 20–40g protein per meal with a particular focus on <a href="https://onlinelibrary.wiley.com/doi/epdf/10.1111/jhn.12838">breakfast and lunch</a> and an overall daily protein intake of at least <a href="https://apps.who.int/iris/handle/10665/43411">0.8g</a> per kg of body weight for <a href="https://pubmed.ncbi.nlm.nih.gov/35187864/">muscle health</a> </li> <li> fibre-rich foods, such as vegetables and whole grains. These make you feel full and <a href="https://pubmed.ncbi.nlm.nih.gov/32142510/">stabilise your blood sugar</a> levels. Examples include broccoli, quinoa, brown rice, oats, beans, lentils and bran cereals. Substitute refined carbs high in sugar like processed snack bars, soft drink or baked goods for more complex ones like whole grain bread or wholewheat muffins, or nut and seed bars or energy bites made with chia seeds and oats </li> </ul> 2) manage your stress levels. Practise stress-reduction techniques like meditation, deep breathing, or yoga to manage emotional triggers for cravings. Practising <a href="https://pubmed.ncbi.nlm.nih.gov/30570305/">mindful eating</a>, by eating slowly and tuning into bodily sensations, can also reduce daily calorie intake and curb cravings and stress-driven eating 3) get enough sleep. Aim for <a href="https://pubmed.ncbi.nlm.nih.gov/33054337/">seven to eight</a> hours of quality sleep per night, with a minimum of seven hours. <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9031614/">Lack of sleep</a> can disrupt hormones that regulate hunger and cravings 4) control your portions. If you decide to indulge in a treat, control your portion size to avoid overindulging. Overcoming cravings for sugar, salt and carbs when trying to eat healthily or lose weight is undoubtedly a formidable challenge. Remember, it’s a journey, and setbacks may occur. Be patient with yourself – your success is not defined by occasional cravings but by your ability to manage and overcome them.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/212114/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/hayley-oneill-1458016">Hayley O'Neill</a>, Assistant Professor, Faculty of Health Sciences and Medicine, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Mothers’ dieting habits and self-talk have profound impact on daughters − 2 psychologists explain how to cultivate healthy behaviors and body image

<a href="https://theconversation.com/profiles/janet-j-boseovski-451496">Janet J. Boseovski</a>, <a href="https://theconversation.com/institutions/university-of-north-carolina-greensboro-2069">University of North Carolina – Greensboro</a> and <a href="https://theconversation.com/profiles/ashleigh-gallagher-1505989">Ashleigh Gallagher</a>, <a href="https://theconversation.com/institutions/university-of-north-carolina-greensboro-2069">University of North Carolina – Greensboro</a> Weight loss is one of the most common health and appearance-related goals. Women and <a href="https://www.cdc.gov/nchs/products/databriefs/db340.htm">teen girls</a> are <a href="https://www.cdc.gov/nchs/products/databriefs/db313.htm">especially likely to pursue dieting</a> to achieve weight loss goals even though a great deal of research shows that <a href="https://theconversation.com/what-thin-people-dont-understand-about-dieting-86604">dieting doesn’t work over the long term</a>. We are a <a href="https://www.duck-lab.com/people">developmental psychologist</a> and a <a href="https://psy.uncg.edu/directory/ashleigh-gallagher/">social psychologist</a> who together wrote a forthcoming book, “Beyond Body Positive: A Mother’s Evidence-Based Guide for Helping Girls Build a Healthy Body Image.” In the book, we address topics such as the effects of maternal dieting behaviors on daughters’ health and well-being. We provide information on how to build a foundation for healthy body image beginning in girlhood. <h2>Culturally defined body ideals</h2> Given the strong influence of social media and other cultural influences on body ideals, it’s understandable that so many people pursue diets aimed at weight loss. <a href="https://communityhealth.mayoclinic.org/featured-stories/tiktok-diets">TikTok</a>, YouTube, Instagram and celebrity websites feature slim influencers and “how-tos” for achieving those same results in no time. For example, women and teens are engaging in rigid and extreme forms of exercise such as 54D, a program to <a href="https://54d.com/">achieve body transformation in 54 days</a>, or the <a href="https://health.clevelandclinic.org/75-hard-challenge-and-rules">75 Hard Challenge</a>, which is to follow five strict rules for 75 days. For teens, these pursuits are likely fueled by trendy body preoccupations such as the desire for “<a href="https://www.nytimes.com/2024/02/06/well/move/tiktok-legging-legs-eating-disorders.html">legging legs</a>.” Women and teens have also been been inundated with recent messaging around <a href="https://theconversation.com/drugs-that-melt-away-pounds-still-present-more-questions-than-answers-but-ozempic-wegovy-and-mounjaro-could-be-key-tools-in-reducing-the-obesity-epidemic-205549">quick-fix weight loss drugs</a>, which come with a lot of caveats. Dieting and weight loss goals are highly individual, and when people are intensely self-focused, it is <a href="https://doi.org/10.1521/jscp.2000.19.1.70">possible to lose sight of the bigger picture</a>. Although women might wonder what the harm is in trying the latest diet, science shows that dieting behavior doesn’t just affect the dieter. In particular, for women who are mothers or who have other girls in their lives, these behaviors affect girls’ emerging body image and their health and well-being. <h2>The profound effect of maternal role models</h2> Research shows that mothers and maternal figures <a href="https://doi.org/10.1016/j.brat.2017.11.001">have a profound influence on their daughters’ body image</a>. The opportunity to influence girls’ body image comes far earlier than adolescence. In fact, research shows that these influences on body image <a href="https://www.teenvogue.com/story/how-toxic-diet-culture-is-passed-from-moms-to-daughters">begin very early in life</a> – <a href="https://doi.org/10.1016/bs.acdb.2016.10.006">during the preschool years</a>. Mothers may feel that they are being discreet about their dieting behavior, but little girls are watching and listening, and they are far more observant of us than many might think. For example, one study revealed that compared with daughters of nondieting women, 5-year-old girls whose mothers dieted <a href="https://doi.org/10.1016/S0002-8223(00)00339-4">were aware of the connection between dieting and thinness</a>. Mothers’ eating behavior does not just affect girls’ ideas about dieting, but also their daughters’ eating behavior. The amount of food that mothers eat <a href="https://doi.org/10.1016/j.appet.2018.04.018">predicts how much their daughters will eat</a>. In addition, daughters whose mothers are dieters are <a href="https://doi.org/10.1016/j.appet.2018.04.018">more likely to become dieters themselves</a> and are also <a href="https://doi.org/10.1016/j.eatbeh.2007.03.001">more likely to have a negative body image</a>. Negative body image is <a href="https://theconversation.com/mounting-research-documents-the-harmful-effects-of-social-media-use-on-mental-health-including-body-image-and-development-of-eating-disorders-206170">not a trivial matter</a>. It affects girls’ and women’s mental and physical well-being in a <a href="https://doi.org/10.1177/1359105317710815">host of ways</a> and <a href="https://doi.org/10.1016/j.brat.2011.06.009">can predict the emergence of eating disorders</a>. <h2>Avoiding ‘fat talk’</h2> What can moms do, then, to serve their daughters’ and their own health? They can focus on small steps. And although it is best to begin these efforts early in life – in girlhood – it is never too late to do so. For example, mothers can consider how they think about and talk about themselves around their daughters. Engaging in “fat talk” may inadvertently send their daughters the message that larger bodies are bad, <a href="https://doi.org/10.1016/j.bodyim.2020.07.004">contributing to weight bias</a> and negative self-image. Mothers’ fat talk also <a href="https://doi.org/10.1080/15267431.2021.1908294">predicts later body dissatisfaction in daughters</a>. And negative self-talk isn’t good for mothers, either; it is associated with <a href="https://doi.org/10.1177/1359105318781943">lower motivation and unhealthful eating</a>. Mothers can instead practice and model self-compassion, which involves treating oneself the way <a href="https://doi.org/10.1016/j.bodyim.2016.03.003">a loving friend might treat you</a>. In discussions about food and eating behavior, it is important to avoid moralizing certain kinds of food by labeling them as “good” or “bad,” as girls may extend these labels to their personal worth. For example, a young girl may feel that she is being “bad” if she eats dessert, if that is what she has learned from observing the women around her. In contrast, she may feel that she has to eat a salad to be “good.” Moms and other female role models can make sure that the dinner plate sends a healthy message to their daughters by showing instead that all foods can fit into a balanced diet when the time is right. Intuitive eating, which emphasizes paying attention to hunger and satiety and allows flexibility in eating behavior, is associated with <a href="https://doi.org/10.1007/s40519-020-00852-4">better physical and mental health in adolescence</a>. Another way that women and especially moms can buffer girls’ body image is by helping their daughters <a href="https://doi.org/10.1016/j.bodyim.2021.12.009">to develop media literacy</a> and to think critically about the nature and purpose of media. For example, moms can discuss the misrepresentation and distortion of bodies, such as the use of filters to enhance physical appearance, on social media. <h2>Focusing on healthful behaviors</h2> One way to begin to focus on health behaviors rather than dieting behaviors is to develop respect for the body and to <a href="https://theconversation.com/body-neutrality-what-it-is-and-how-it-can-help-lead-to-more-positive-body-image-191799">consider body neutrality</a>. In other words, prize body function rather than appearance and spend less time thinking about your body’s appearance. Accept that there are times when you may not feel great about your body, and that this is OK. To feel and look their best, mothers can aim to stick to a <a href="https://theconversation.com/whats-the-best-diet-for-healthy-sleep-a-nutritional-epidemiologist-explains-what-food-choices-will-help-you-get-more-restful-zs-219955">healthy sleep schedule</a>, manage their stress levels, <a href="https://theconversation.com/fiber-is-your-bodys-natural-guide-to-weight-management-rather-than-cutting-carbs-out-of-your-diet-eat-them-in-their-original-fiber-packaging-instead-205159">eat a varied diet</a> that includes all of the foods that they enjoy, and <a href="https://theconversation.com/the-runners-high-may-result-from-molecules-called-cannabinoids-the-bodys-own-version-of-thc-and-cbd-170796">move and exercise their bodies regularly</a> as lifelong practices, rather than engaging in quick-fix trends. Although many of these tips sound familiar, and perhaps even simple, they become effective when we recognize their importance and begin acting on them. Mothers can work toward modeling these behaviors and tailor each of them to their daughter’s developmental level. It’s never too early to start. <h2>Promoting healthy body image</h2> Science shows that several personal characteristics are associated with body image concerns among women. For example, research shows that women who are <a href="https://doi.org/10.1016/j.bodyim.2020.02.001">higher in neuroticism</a> <a href="https://doi.org/10.1186/2050-2974-1-2">and perfectionism</a>, <a href="https://doi.org/10.3389/fpsyg.2022.983534">lower in self-compassion</a> or <a href="https://doi.org/10.1016/j.bodyim.2013.08.001">lower in self-efficacy</a> are all more likely to struggle with negative body image. Personality is frequently defined as a person’s characteristic pattern of thoughts, feelings and behaviors. But if they wish, <a href="https://doi.org/10.1002/per.1945">mothers can change personality characteristics</a> that they feel aren’t serving them well. For example, perfectionist tendencies – such as setting unrealistic, inflexible goals – can be examined, challenged and replaced with more rational thoughts and behaviors. A woman who believes she must work out every day can practice being more flexible in her thinking. One who thinks of dessert as “cheating” can practice resisting moral judgments about food. Changing habitual ways of thinking, feeling and behaving certainly takes effort and time, but it is far more likely than diet trends to bring about sustainable, long-term change. And taking the first steps to modify even a few of these habits can positively affect daughters. In spite of all the noise from media and other cultural influences, mothers can feel empowered knowing that they have a significant influence on their daughters’ feelings about, and treatment of, their bodies. In this way, mothers’ modeling of healthier attitudes and behaviors is a sound investment – for both their own body image and that of the girls they love.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/221968/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/janet-j-boseovski-451496">Janet J.

Eating leafy greens could be better for oral health than using mouthwash

Typical treatments include <a href="https://www.nature.com/articles/s41598-020-61912-4">mouthwash</a> and in severe cases, <a href="https://www.magonlinelibrary.com/doi/abs/10.12968/vetn.2017.8.10.542">antibiotics</a>. These treatments have side effects, such as dry mouth, the development of <a href="https://pubmed.ncbi.nlm.nih.gov/30967854/">antimicrobial resistance</a> and increased <a href="https://www.nature.com/articles/s41598-020-61912-4">blood pressure</a>. But research has indicated that a molecule called <a href="https://www.nature.com/articles/s41598-020-69931-x">nitrate</a>, which is found in leafy green vegetables, has fewer side effects and offers greater benefits for oral health.

Inadequate brushing and flossing leads to the build up of <a href="https://www.nature.com/articles/s41598-020-69931-x">dental plaque</a>, a sticky layer of bacteria, on the surface of teeth and gums. Plaque causes tooth decay and gum disease. Sugary and acidic foods, dry mouth, and smoking can also contribute to bad breath, tooth decay, and gum infections. The two main types of gum disease are gingivitis and periodontitis. <a href="https://www.spandidos-publications.com/10.3892/etm.2019.8381">Gingivitis</a> causes redness, swelling and bleeding of the gums. <a href="https://www.spandidos-publications.com/10.3892/etm.2019.8381">Periodontitis</a> is a more advanced form of gum disease, causing damage to the soft tissues and bones supporting the teeth. Periodontal disease can therefore, lead to tooth loss and, when bacteria from the mouth enter the bloodstream, can also contribute to the development of <a href="https://www.nature.com/articles/bdjteam2015163">systemic disorders</a> such as cardiovascular disease, dementia, diabetes and rheumatoid arthritis. <h2>Leafy greens may be the secret</h2> Leafy greens and root vegetables are bursting with <a href="https://www.sciencedirect.com/science/article/pii/S2666149723000312">vitamins, minerals, and antioxidants</a> – and it’s no secret that a diet consisting of these vegetables is crucial for maintaining a healthy weight, boosting the immune system, and preventing <a href="https://journals.sagepub.com/doi/10.1177/2048004016661435">heart disease, cancer and diabetes.</a> The multiple health benefits of leafy greens are partly because spinach, lettuce and beetroots are brimming with <a href="https://www.nature.com/articles/s41598-020-69931-x">nitrate</a>, which can be reduced to nitric oxide by nitrate-reducing bacteria inside the mouth. <figure><iframe src="https://www.youtube.com/embed/7zrRlMGeBes?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption>Popeye knew a thing or two about the health benefits of eating leafy greens.

However, in the mouth, it helps to prevent the overgrowth of bad bacteria and reduces <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0243755#:%7E:text=Nitrate%2Drich%20beetroot%20juice%20offsets,healthy%20male%20runners%20%7C%20PLOS%20ONE">oral acidity</a>, both of which can cause gum disease and tooth decay. As part of our research on nitrate and oral health, <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0243755#:%7E:text=Nitrate%2Drich%20beetroot%20juice%20offsets,healthy%20male%20runners%20%7C%20PLOS%20ONE">we studied competitive athletes</a>. <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9839431/">Athletes are prone to gum disease</a> due to high intake of carbohydrates – which can cause inflammation of the gum tissues – stress, and dry mouth from breathing hard during training. Our study showed that beetroot juice (containing approximately 12 <a href="https://www.nursingtimes.net/students/an-easy-guide-to-mmols-09-02-2012/">millimole</a> of nitrate) protected their teeth from acidic sports drinks and carbohydrate gels during exercise – suggesting that nitrate could be used as a prebiotic by athletes to reduce the risk of tooth decay. Nitrate offers a lot of promise as an oral health <a href="https://www.nature.com/articles/s41598-020-69931-x">prebiotic</a>. Good oral hygiene and a nitrate rich diet could be the key to a healthier body, a vibrant smile and disease-free gums. This is good news for those most at risk of oral health deterioration such as <a href="https://www.news-medical.net/health/Periodontitis-and-Pregnancy.aspx">pregnant women</a>, and <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8771712/">the elderly</a>. In the UK, antiseptic mouthwashes containing <a href="https://www.nature.com/articles/s41598-020-61912-4">chlorhexidine</a> are commonly used to treat dental plaque and gum disease. Unfortunately, these mouthwashes are a blunderbuss approach to oral health, as they indiscriminately remove both good and bad bacteria and increase oral acidity, which can cause disease. Worryingly, early research also indicates that chlorhexidine may contribute to <a href="https://pubmed.ncbi.nlm.nih.gov/30967854/">antimicrobial resistance</a>. Resistance occurs when bacteria and fungi survive the effects of one or more <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4768623/">antimicrobial drugs</a> due to repeated exposure to these treatments. Antimicrobial resistance is a <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(21)02724-0/fulltext">global health concern</a>, predicted to cause 10 million deaths yearly by the year 2050. In contrast, dietary nitrate is more targeted. Nitrate eliminates disease-associated bacteria, reduces oral acidity and creates a balanced <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2944498/">oral microbiome</a>. The oral microbiome refers to all the microorganisms in the mouth. Nitrate offers exciting potential as an <a href="https://www.nature.com/articles/s41598-020-69931-x">oral health prebiotic</a>, which can be used to prevent disease onset or limit disease progression. <h2>How many leafy greens for pearly whites?</h2> So how much should we consume daily? As a rule of thumb, a generous helping of spinach, kale or beetroot at mealtimes contains about 6-10 mmol of nitrate and offers immediate health benefits. Work we have done with our collaborators has shown that treating <a href="https://www.nature.com/articles/s41598-020-69931-x">plaque samples</a> from periodontal disease patients with 6.5 mmol of nitrate increased healthy bacteria levels and reduced acidity. For example, consuming <a href="https://aap.onlinelibrary.wiley.com/doi/full/10.1002/JPER.20-0778">lettuce juice</a> for two weeks reduced gum inflammation and increased healthy bacteria levels in patients with gum disease. Growing evidence suggests that nitrate is a cornerstone of oral health. Crunching on a portion of vegetables at mealtimes can help to prevent or treat oral disease and keeps the mouth fresh and healthy.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/221181/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/mia-cousins-burleigh-1201153">Mia Cousins Burleigh</a>, Lecturer, School of Health and Life Sciences, <a href="https://theconversation.com/institutions/university-of-the-west-of-scotland-1385">University of the West of Scotland</a> and <a href="https://theconversation.com/profiles/siobhan-paula-moran-1506183">Siobhan Paula Moran</a>, PhD candidate, School of Health and Life Sciences, <a href="https://theconversation.com/institutions/university-of-the-west-of-scotland-1385">University of the West of Scotland</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

How dieting, weight suppression and even misuse of drugs like Ozempic can contribute to eating disorders

<a href="https://theconversation.com/profiles/samantha-withnell-1504436">Samantha Withnell</a>, <a href="https://theconversation.com/institutions/western-university-882">Western University</a> and <a href="https://theconversation.com/profiles/lindsay-bodell-1504260">Lindsay Bodell</a>, <a href="https://theconversation.com/institutions/western-university-882">Western University</a> Up to 72 per cent of women and 61 per cent of men are dissatisfied with their weight or <a href="https://doi.org/10.1016/j.eatbeh.2014.04.010">body image</a>, according to a U.S. study. Globally, millions of people <a href="https://doi.org/10.1111%2Fobr.12466">attempt to lose weight</a> every year with the hope that weight loss will have positive effects on their body image, health and quality of life. However, these motivated individuals often struggle to maintain new diets or exercise regimens. The rise of medications such as semaglutides, like <a href="https://dhpp.hpfb-dgpsa.ca/dhpp/resource/101298">Ozempic</a> or <a href="https://dhpp.hpfb-dgpsa.ca/dhpp/resource/101765">Wegovy</a>, <a href="https://www.cbc.ca/news/health/ozempic-weight-loss-1.6772021">might be viewed as an appealing “quick fix”</a> alternative to meet weight loss goals. Research led by our team and others suggests that such attempts to lose weight often do more harm than good, and even increase the risk of <a href="https://osf.io/9stq2">developing an eating disorder</a>. <h2>Weight loss and eating disorders</h2> Eating disorders are <a href="https://doi.org/10.1002/eat.20589">serious mental health conditions</a> primarily characterized by extreme patterns of under- or over-eating, concerns about one’s shape or body weight or other behaviours intended to influence body shape or weight such as exercising excessively or self-inducing vomiting. Although once thought to only affect young, white adolescent girls, eating disorders do not discriminate; eating disorders can develop in people of <a href="https://doi.org/10.1002/erv.2553">any age, sex, gender or racial/ethnic background</a>, with an estimated <a href="https://nedic.ca/general-information/">one million Canadians</a> suffering from an eating disorder at any given time. Feb. 1 to 7 is <a href="https://nedic.ca/edaw/">National Eating Disorders Awareness Week</a>. As a clinical psychologist and clinical psychology graduate student, our research has focused on how eating disorders develop and what keeps them going. Pertinent to society’s focus on weight-related goals, our research has examined associations between weight loss and eating disorder symptoms. <h2>Eating disorders and ‘weight suppression’</h2> In eating disorders research, the state of maintaining weight loss is referred to as “weight suppression.” Weight suppression is typically defined as the difference between a person’s current weight and their highest lifetime weight (excluding pregnancy). Despite the belief that weight loss will improve body satisfaction, we found that in a sample of over 600 men and women, weight loss had no impact on women’s negative body image and was associated with increased body dissatisfaction in <a href="https://doi.org/10.1016/j.bodyim.2023.01.011">men</a>. Importantly, being more weight suppressed has been associated with the <a href="https://doi.org/10.1093/ajcn/nqaa146">onset of eating disorders</a>, including anorexia nervosa and bulimia nervosa. <a href="https://doi.org/10.1007/s11920-018-0955-2">One proposed explanation</a> for the relationship between weight suppression and eating disorders is that maintaining weight loss becomes increasingly difficult as body systems that <a href="https://doi.org/10.3945/ajcn.110.010025">reduce metabolic rate and energy expenditure, and increase appetite</a>, are activated to promote weight gain. There is growing awareness that <a href="https://doi.org/10.1136/bmj.g2646">weight regain is highly likely following conventional diet programs</a>. This might lead people to engage in more and more extreme behaviours to control their weight, or they might shift between extreme restriction of food intake and episodes of overeating or binge eating, the characteristic symptoms of bulimia nervosa. <h2>Ozempic and other semaglutide drugs</h2> Semaglutide drugs like Ozempic and Wegovy are part of a class of drug called <a href="https://pdf.hres.ca/dpd_pm/00067924.PDF">glucagon-like peptide-1 agonists (GLP-1As)</a>. These drugs work by mimicking the hormone GLP-1 to interact with neural pathways that signal satiety (fullness) and slow stomach emptying, leading to reduced food intake. Although GLP-1As are indicated to treat Type 2 diabetes, <a href="https://www.cbc.ca/news/canada/london/ozempic-off-label-1.6884141">they are increasingly prescribed off-label</a> or being <a href="https://www.bbc.com/news/health-67414203">illegally purchased</a> without a prescription because of their observed effectiveness at inducing weight loss. Although medications like Ozempic do often lead to weight loss, the rate of weight loss may <a href="https://doi.org/10.1001/jama.2021.3224">slow down or stop over time</a>. Research by Lindsay Bodell, one of the authors of this story, and her colleagues on weight suppression may help explain why effects of semaglutides diminish over time, as <a href="https://doi.org/10.1016/j.physbeh.2019.112565">weight suppression is associated with reduced GLP-1 response</a>. This means those suppressing their weight could become less responsive to the satiety signals activated by GLP-1As. Additionally, weight loss effects are only seen for as long as the medication is taken, meaning those who take these drugs to achieve some weight loss goal are <a href="https://doi.org/10.1111/dom.14725">likely to regain most, if not all, weight lost</a> when they stop taking the medication. <h2>Risks of dieting and weight-loss drugs</h2> The growing market for off-label weight loss drugs is concerning, because of the exacerbation of <a href="https://theconversation.com/ozempic-the-miracle-drug-and-the-harmful-idea-of-a-future-without-fat-211661">weight stigma</a> and the serious <a href="https://doi.org/10.1016/j.jand.2022.01.004">health risks</a> associated with unsupervised weight loss, including developing eating disorders. Researchers and health professionals are already raising the alarm about the use of GLP-1As in children and adolescents, due to concerns about their possible <a href="https://doi.org/10.1017/cts.2023.612">impact on growth and development</a>. Moreover, popular weight-loss methods, whether they involve pills or “crash diets,” often mimic symptoms of eating disorders. For example, intermittent fasting diets that involve long periods of fasting followed by short periods of food consumption may mimic and <a href="https://doi.org/10.1016/j.eatbeh.2022.101681">increase the risk of developing binge eating problems</a>. The use of diet pills or laxatives to lose weight has been found to increase the risk of <a href="https://doi.org/10.2105/AJPH.2019.305390">being diagnosed with an eating disorder in the next one to three years</a>. Drugs like Ozempic may also be <a href="https://doi.org/10.1002/eat.24109">misused by individuals already struggling with an eating disorder</a> to suppress their appetite, compensate for binge eating episodes or manage fear of weight gain. Individuals who are already showing signs of an eating disorder, such as limiting their food intake and intense concerns about their weight, may be most at risk of spiralling from a weight loss diet or medication into an eating disorder, <a href="https://doi.org/10.1002/eat.24116">even if they only lose a moderate amount of weight</a>. People who are dissatisfied with their weight or have made multiple attempts to lose weight often feel pressured to try increasingly drastic methods. However, any diet, exercise program or weight-loss medication promising a quick fix for weight loss should be treated with extreme caution. At best, you may gain the weight back; at worst, you put yourself at risk for much more serious eating disorders and other health problems.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/221514/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/samantha-withnell-1504436">Samantha Withnell</a>, PhD Candidate, Clinical Psychology, <a href="https://theconversation.com/institutions/western-university-882">Western University</a> and <a href="https://theconversation.com/profiles/lindsay-bodell-1504260">Lindsay Bodell</a>, Assistant Professor of Psychology, <a href="https://theconversation.com/institutions/western-university-882">Western University</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

I’m trying to lose weight and eat healthily. Why do I feel so hungry all the time? What can I do about it?

<a href="https://theconversation.com/profiles/nick-fuller-219993">Nick Fuller</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> Benjamin Franklin, one of the founding fathers of the United States, famously said nothing is certain except death and taxes. But I think we can include “you’ll feel hungry when you’re trying to lose weight” as another certainty. The reason is basic biology. So how does this work – and what can you do about it? <h2>Hormones control our feelings of hunger</h2> Several hormones play an essential role in regulating our feelings of hunger and fullness. The most important are ghrelin – often called the hunger hormone – and leptin. When we’re hungry, <a href="https://pubmed.ncbi.nlm.nih.gov/11739476/">ghrelin</a> is released by our stomach, lighting up a part of our brain called the hypothalamus to tell us to eat. When it’s time to stop eating, hormones, including <a href="https://pubmed.ncbi.nlm.nih.gov/8717038/">leptin</a>, are released from different organs, such as our gut and fat tissue, to signal to the brain that we’re full. <h2>Dieting disrupts the process</h2> But when we change our diet and start losing weight, we disrupt how these <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4766925/">appetite hormones function</a>. This triggers a process that stems from our hunter-gatherer ancestors. Their bodies developed this mechanism as a survival response to adapt to periods of deprivation and protect against starvation. The levels of hormones <a href="https://pubmed.ncbi.nlm.nih.gov/23126426/">managing our hunger increase</a>, making us feel hungrier to tell us to eat more, while the ones responsible for signalling we’re full decrease their levels, intensifying our feelings of hunger. We end up increasing our calorie consumption so we eat more to regain the weight we lost. But worse, even after the kilos creep back on, <a href="https://pubmed.ncbi.nlm.nih.gov/22029981/">our appetite hormones don’t restore</a> to their normal levels – they keep telling us to eat more so we put on a little extra fat. This is our body’s way of preparing for the next bout of starvation we will impose through dieting. Fortunately, there are things we can do to manage our appetite, including: <h2>1. Eating a large, healthy breakfast every day</h2> One of the easiest ways to manage our feelings of hunger throughout the day is to eat most of our food earlier in the day and taper our meal sizes so dinner is the smallest meal. <a href="https://pubmed.ncbi.nlm.nih.gov/32073608/">Research</a> shows a low-calorie or small breakfast leads to increased feelings of hunger, specifically appetite for sweets, across the course of the day. <a href="https://www.cell.com/cell-metabolism/fulltext/S1550-4131(22)00344-8">Another study</a> found the same effect. Participants went on a calorie-controlled diet for two months, where they ate 45% of their calories for breakfast, 35% at lunch and 20% at dinner for the first month, before switching to eat their largest meal in the evening and their smallest in the morning. Eating the largest meal at breakfast resulted in decreased hunger throughout the day. <a href="https://pubmed.ncbi.nlm.nih.gov/32073608/">Research</a> also shows we burn the calories from a meal 2.5-times more efficiently in the morning than the evening. So emphasising breakfast over dinner is good not just for hunger control, but also weight management. <h2>2. Prioritising protein</h2> Protein helps contain feelings of hunger. This is because protein-rich foods such as lean meats, tofu and beans suppress the appetite-stimulating ghrelin and stimulate another hormone called <a href="https://www.sciencedirect.com/science/article/pii/S1550413106002713">peptide YY</a> that makes you feel full. And just as eating a breakfast is vital to managing our hunger, what we eat is important too, with <a href="https://pubmed.ncbi.nlm.nih.gov/24703415/">research</a> confirming a breakfast containing protein-rich foods, such as eggs, will leave us feeling fuller for longer. But this doesn’t mean just eating foods with protein. Meals need to be balanced and include a source of protein, wholegrain carb and healthy fat to meet our dietary needs. For example, eggs on wholegrain toast with avocado. <h2>3. Filling up with nuts and foods high in good fats and fibre</h2> Nuts often get a bad rap – thanks to the misconception they cause weight gain – but nuts can help us manage our hunger and weight. The filling fibre and good fats found in nuts take longer to digest, meaning our hunger is satisfied for longer. <a href="https://pubmed.ncbi.nlm.nih.gov/12791613/">Studies</a> suggest you can include up to 68 grams per day of nuts without affecting your weight. Avocados are also high in fibre and heart-healthy monounsaturated fats, making them another excellent food for managing feelings of fullness. This is backed by a <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6567160/">study</a> confirming participants who ate a breakfast incorporating avocado felt more satisfied and less hungry than participants who ate a meal containing the same calories but with lower fat and fibre content. Similarly, eating foods that are high in soluble fibre – such as <a href="https://pubmed.ncbi.nlm.nih.gov/24820437/">beans</a> and vegetables – make us feel fuller. This type of fibre attracts water from our gut, forming a gel that slows digestion. <h2>4. Eating mindfully</h2> When we take time to really be aware of and enjoy the food we’re eating, we slow down and eat far less. A <a href="https://pubmed.ncbi.nlm.nih.gov/28718396/">review</a> of 68 studies found eating mindfully helps us better recognise feelings of fullness. Mindful eating provides our brain enough time to recognise and adapt to the signals from our stomach telling us we’re full. Slow down your food consumption by sitting at the dinner table and use smaller utensils to reduce the volume of food you eat with each mouthful. <h2>5. Getting enough sleep</h2> Sleep deprivation disturbs our <a href="https://www.sciencedirect.com/science/article/abs/pii/S1389945708700133">appetite hormones</a>, increasing our feelings of hunger and <a href="https://www.nature.com/articles/ncomms3259">triggering cravings</a>. So aim to get at least seven hours of uninterrupted sleep a night. Try switching off your devices <a href="https://journals.sagepub.com/doi/full/10.1177/1477153515584979">two hours before bed</a> to boost your body’s secretion of sleep-inducing hormones like melatonin. <h2>6. Managing stress</h2> Stress increases our <a href="https://pubmed.ncbi.nlm.nih.gov/18568078/">body’s production of cortisol</a> and triggers food cravings. So take time out when you need it and set aside time for stress-relieving activities. This can be as simple as getting outdoors. A <a href="https://www.frontiersin.org/articles/10.3389/fpsyg.2019.00722/full">2019 study</a> found sitting or walking outdoors at least three times a week could reduce cortisol levels by 21%. <h2>7. Avoiding depriving ourselves</h2> When we change our diet to lose weight or eat healthier, we typically restrict certain foods or food groups. However, this <a href="https://pubmed.ncbi.nlm.nih.gov/18568078/">heightens activity</a> in our mesocorticolimbic circuit – the reward system part of the brain – often resulting in us craving the foods we’re trying to avoid. Foods that give us pleasure release feel-good chemicals called endorphins and learning chemicals called dopamine, which enable us to remember – and give in to – that feel-good response. When we change our diet, activity in our hypothalamus – the clever part of the brain that regulates emotions and food intake – <a href="https://pubmed.ncbi.nlm.nih.gov/18568078/">also reduces</a>, decreasing our control and judgement. It often triggers a psychological response dubbed the “what-the-hell effect”, when we indulge in something we think we shouldn’t feel guilty about and then go back for even more. Don’t completely cut out your favourite foods when you go on a diet or deprive yourself if you’re hungry. It will take the pleasure out of eating and eventually you’ll give into your cravings. At the Boden Group, Charles Perkins Centre, we are studying the science of obesity and running clinical trials for weight loss.

When it comes to weight, your ‘diet’ is much more than what you eat

Atkins, keto, palaeo, gluten-free, low-carb, low-fat, high-fat, raw, vegan, vego, pescatarian – phew, that’s a lot of different diets! <div class="copy"> And it’s by no means an exhaustive list. The old adage ‘you are what you eat’ has come to be a mantra for good diet and health. It was originally coined by 19th-century German philosopher Ludwig Feuerbach, himself drawing on commentary by an earlier French gourmand Anthelme Brillat-Savarin. Increasingly, science is finding new connections between diet and our overall picture of health. You may have heard how our gut microbiome acts as a second brain, or that avoiding unprocessed foods can lead to all-cause mortality. But when it comes to many fad diets that promise quick weight loss or improved health, the science can sometimes be skimp. This can change over time as researchers test the influence of diet on general health, weight management and as a medical treatment. The <a href="https://cosmosmagazine.com/health/mediterranean-diet-heart-dementia/">Mediterranean diet</a> is probably closest to the mark as a lifestyle of choice, in terms of overall health, nutrition, and diet science. It emphasises <a href="https://cosmosmagazine.com/health/nutrition/plant-based-diets-could-prevent-type-2-diabetes/">fruit and vegetable</a> consumption, with some wholegrain breads and cereals, legumes, nuts, seeds and fish, with olive oil as a primary fat source. This diet is either explicitly endorsed by many health authorities around the world such as the <a href="https://www.heart.org/en/healthy-living/healthy-eating/eat-smart/nutrition-basics/mediterranean-diet" target="_blank" rel="noreferrer noopener">American Heart Association</a>, the <a href="https://www.racgp.org.au/clinical-resources/clinical-guidelines/handi/handi-interventions/nutrition/mediterranean-diet-for-reducing-cardiovascular-dis" target="_blank" rel="noreferrer noopener">Royal Australian College of General Practitioners</a> as a diet for lowering cardiovascular disease risk, or used as a basis for other recommendations. The World Health Organization also <a href="https://www.who.int/europe/news/item/07-05-2018-fostering-healthier-and-more-sustainable-diets-learning-from-the-mediterranean-and-new-nordic-experience" target="_blank" rel="noreferrer noopener">advises</a> on ways for the Mediterranean and similar New Nordic diets to be implemented as <a href="https://iris.who.int/bitstream/handle/10665/326264/9789289053013-eng.pdf?sequence=3" target="_blank" rel="noreferrer noopener">health policy</a>. But diet might be better considered about more than what goes in one’s mouth. Dr Evangeline Mantzioris, Program Director of the Nutrition and Food Sciences Degree at the University of South Australia, says a truer interpretation of the world extends beyond merely food and drink. “The word diet actually derives from the Greek word diaita, which means the way you choose to live your life,” Mantzioris told the <a href="https://cosmosmagazine.com/tag/debunks/" target="_blank" rel="noreferrer noopener">Debunks podcast.</a> “So it’s not just about the food, it’s about the exercise, it’s about the social interaction, it’s about the rest. It’s about the sleep. It’s all of that.” The WHO’s 2019 Health Evidence Network Synthesis Report also acknowledges both social and sleep components of the lifestyle, noting shared eating practices, post-meal siestas and lengthy meal times all contribute to positive health effects. In terms of the nutritional component, Mantzioris notes that adherence to the diet requires not just an uptake of olive oil, but cutting down on less beneficial foods and an active lifestyle. “It’s not just the olive oil, it’s dropping down the meat, it’s mainly a plant food diet, it’s purposeful exercise,” she says. “I’m always a little bit nervous when people just talk about the diet and the food without considering the rest of it. “In the 60s, when the health benefits of the Mediterranean diet were seen […] they were out there harvesting, growing their food, preparing their food, doing all that sort of purposeful exercise in the outdoor environment, often in quite steep terrain. So that is just as important. “The Mediterranean diet continues to be shown to be quite healthy and beneficial in terms of improving chronic disease risk, even without weight loss.” Mantzioris says that the diet has also been shown to improve cognitive and mental health outcomes. Diet is the focus of the latest episode of Debunks from Cosmos and 9Podcasts, where we dive not simply into what makes a good diet, but the principles that dieticians and nutritionists look for when recommending one for a patient to consider. <iframe title="Weight: Do diets actually work?" src="https://omny.fm/shows/debunks/weight-do-diets-actually-work/embed?style=Artwork" width="100%" height="180" frameborder="0"></iframe>  <img id="cosmos-post-tracker" style="opacity: 0; height: 1px!important; width: 1px!important; border: 0!important; position: absolute!important; z-index: -1!important;" src="https://syndication.cosmosmagazine.com/?id=287991&title=When+it+comes+to+weight%2C+your+%E2%80%98diet%E2%80%99+is+much+more+than+what+you+eat" width="1" height="1" loading="lazy" aria-label="Syndication Tracker" data-spai-target="src" data-spai-orig="" data-spai-exclude="nocdn" /></div> <div class="copy"> </div> <div>Image credits: Shutterstock</div> <div> </div> <div><a href="https://cosmosmagazine.com/health/body-and-mind/diet-is-much-more-than-what-you-eat/">This article</a> was originally published on <a href="https://cosmosmagazine.com">Cosmos Magazine</a> and was written by <a href="https://cosmosmagazine.com/contributor/matthew-agius/">Matthew Ward Agius</a>. </div>
