There are many celebrity anecdotes surrounding OMAD and from an evolutionary point of view, it can seem reasonable to suggest that human biology is better suited to less frequent meals. This theory is based on our ancestors often experiencing cycles of feasting and fasting rather than the relatively modern construct of three meals a day.<\/p>\n
But while fasting itself isn\u2019t new, the research on its health impacts is still in its infancy and there are very few studies on OMAD and the evidence supporting other more periodic types of fasting<\/a> can\u2019t necessarily be extrapolated into extreme fasting.<\/p>\n One trial exists on OMAD, where participants ate only one meal a day, or three meals per day, with their calorie intakes tailored to theoretically maintain their current weight.<\/p>\n When on one meal per day they reduced body weight and fat levels<\/a>, and displayed features of \u201cmetabolic flexibility\u201d (changes in measures of how fats and carbohydrates are metabolised). But participants also experienced a loss of muscle and bone mass. This highlights that a focus on weight loss alone can miss the potential downsides of this kind of diet.<\/p>\n Importantly, the results of this study can\u2019t be applied to everyone. Only relatively healthy people were included and no one with obesity, cardiovascular disease, diabetes, mental disorders, eating disorders or other metabolic conditions was allowed to participate.<\/p>\n Furthermore, the trial was small and short, with just 11 participants following the diet for 11 days.<\/p>\n Read more:<\/strong><\/p>\n One of the claims made by supporters of OMAD and other fasting diets is that you can eat whatever you want for the one meal you are eating each day. But if all nutrients for good health are to be obtained in just one meal, it needs to be nutrient dense and balanced to ensure you get a sufficient intake of fibre, protein, vitamins and minerals.<\/p>\n Supplements may help avoid nutritional deficits but they lack the complexity of foods, which means other healthy essentials, such as bioactive compounds, may be missed. This means there may be longer-term consequences for bone, digestive<\/a> and other elements of your health, despite the easy-to-measure and instantly gratifying weight loss.<\/p>\n Indeed, when meal frequency has been studied in larger groups (over 24,000 people) for longer periods (about 15 years), eating just one meal a day was linked to a higher risk of death<\/a> from any cause, and from cardiovascular diseases.<\/p>\n Observational studies like this can\u2019t show the cause of the relationship, but the results were found even when factors like age, gender, race, ethnicity, education, income, smoking, alcohol intake, physical activity, energy intake, food insecurity, snacking habits and health at the start of the study were taken into account.<\/p>\n It\u2019s also important to consider the other roles that food plays in our lives. Food is more than just calories and nutrition. It\u2019s part of our culture, society, celebrations and enjoyment of life.<\/p>\n The social and emotional consequences of OMAD have not been documented but there is data showing that restrictive diets can have significant psychological consequences<\/a>.<\/p>\n Reporting on celebrity trends is part of how pseudoscience and fake news spread in the health and beauty industry<\/a>. There may be limited resources to fully fact-check the articles and few details mentioned of how stringently celebrities are truly following these diets. Plus, their true health, beyond their appearance, isn\u2019t known.<\/p>\n Remember: any information is being shared selectively and facts can be omitted for the sake of the story. As long as stories on celebrity diets remain a good source of \u2018clicks\u2019, they\u2019ll be fraught with clickbait \u2013 and extremes like OMAD give us just that.<\/p>\n The average person considering OMAD, or any other celebrity diet, does not have the same luxuries and supports that celebrities do: the nutritionists, the nannies and the other assorted assistants, for example.<\/p>\n So, we don\u2019t all have the same capacity to deal with the potential side effects that come with extreme fasting, which can include nausea, dizziness, low energy<\/a>, irritability and constipation. Celebrity lifestyles are enticing but this is precisely because they\u2019re so unlike our own.<\/p>\n Celebrities give us many great things, like films, music, art and sports, but they\u2019re not the most reliable source of nutrition information<\/a>. Instead, official dietary guidelines, based on the complete body of nutrition science knowledge should be used for general advice, and qualified health professionals like dietitians should be consulted for your individual needs.<\/p>\n Read more:<\/strong><\/p>\n Is restricting yourself to just one meal a day the secret to staying trim or is it just restrictive eating? <\/p>\n","protected":false},"author":24,"featured_media":27507,"template":"","categories":[54],"acf":{"readingTimeMinutes":"5"},"uagb_featured_image_src":{"full":["https:\/\/c01.purpledshub.com\/uploads\/sites\/42\/2023\/05\/the-great-one-meal-a-day-myth-why-the-celebrity-omad-diet-is-no-weight-loss-miracle.jpg",1200,511,false],"thumbnail":["https:\/\/c01.purpledshub.com\/uploads\/sites\/42\/2023\/05\/the-great-one-meal-a-day-myth-why-the-celebrity-omad-diet-is-no-weight-loss-miracle-150x150.jpg",150,150,true],"medium":["https:\/\/c01.purpledshub.com\/uploads\/sites\/42\/2023\/05\/the-great-one-meal-a-day-myth-why-the-celebrity-omad-diet-is-no-weight-loss-miracle-300x128.jpg",300,128,true],"medium_large":["https:\/\/c01.purpledshub.com\/uploads\/sites\/42\/2023\/05\/the-great-one-meal-a-day-myth-why-the-celebrity-omad-diet-is-no-weight-loss-miracle-768x327.jpg",768,327,true],"large":["https:\/\/c01.purpledshub.com\/uploads\/sites\/42\/2023\/05\/the-great-one-meal-a-day-myth-why-the-celebrity-omad-diet-is-no-weight-loss-miracle-1024x436.jpg",800,341,true],"1536x1536":["https:\/\/c01.purpledshub.com\/uploads\/sites\/42\/2023\/05\/the-great-one-meal-a-day-myth-why-the-celebrity-omad-diet-is-no-weight-loss-miracle.jpg",1200,511,false],"2048x2048":["https:\/\/c01.purpledshub.com\/uploads\/sites\/42\/2023\/05\/the-great-one-meal-a-day-myth-why-the-celebrity-omad-diet-is-no-weight-loss-miracle.jpg",1200,511,false]},"uagb_author_info":{"display_name":"importmanagerhub@sprylab.com","author_link":"https:\/\/c01.purpledshub.com\/bbcsciencefocus\/author\/importmanagerhubsprylab-com\/"},"uagb_comment_info":0,"uagb_excerpt":"Is restricting yourself to just one meal a day the secret to staying trim or is it just restrictive eating?","_links":{"self":[{"href":"https:\/\/c01.purpledshub.com\/bbcsciencefocus\/wp-json\/wp\/v2\/rss_feed\/27506"}],"collection":[{"href":"https:\/\/c01.purpledshub.com\/bbcsciencefocus\/wp-json\/wp\/v2\/rss_feed"}],"about":[{"href":"https:\/\/c01.purpledshub.com\/bbcsciencefocus\/wp-json\/wp\/v2\/types\/rss_feed"}],"author":[{"embeddable":true,"href":"https:\/\/c01.purpledshub.com\/bbcsciencefocus\/wp-json\/wp\/v2\/users\/24"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/c01.purpledshub.com\/bbcsciencefocus\/wp-json\/wp\/v2\/media\/27507"}],"wp:attachment":[{"href":"https:\/\/c01.purpledshub.com\/bbcsciencefocus\/wp-json\/wp\/v2\/media?parent=27506"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/c01.purpledshub.com\/bbcsciencefocus\/wp-json\/wp\/v2\/categories?post=27506"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}What are the risks associated with the OMAD diet?<\/h2>\n
