However, there are important caveats to these conclusions. The authors point out that there are no large, randomized controlled trials that look at how IF patterns affect cardiovascular disease.

Moskovitz advises that you do not need to fast to garner these types of health benefits. If you are going to start OMAD, she recommends having a blood test taken before starting and then again three months later, which will provide a personalized picture of how your body is responding.

If done correctly, you may lose weight on OMAD. As noted, individuals who are pregnant or nursing, under 18, take insulin to manage diabetes, have a past eating disorder , or take food-dependent medication should not follow OMAD.

What is the OMAD diet? Is one meal a day actually good for weight loss? And is it safe? What do British Prime Minister Rishi Sunak and singer Bruce Springsteen have in common?

They're among an ever-growing group of public figures touting the benefits of eating just one meal a day. As a result, the one meal a day OMAD diet is the latest attention-grabbing weight loss trend.

Advocates claim it leads to fast, long-term weight loss and better health, including delaying the ageing process. Like most weight loss programs, the OMAD diet makes big and bold promises. Here's what you need to know about eating one meal a day and what it means for weight loss.

Essentially, the OMAD diet is a type of intermittent fasting, where you fast for 23 hours and consume all your daily calories in one meal eaten within one hour.

The OMAD diet rules are presented as simple and easy to follow:. You can eat whatever you want, provided it fits on a standard dinner plate, with no calorie restrictions or nutritional guidelines to follow. You can drink calorie-free drinks throughout the day water, black tea and coffee.

You must follow a consistent meal schedule, eating your one meal around the same time each day. Along with creating a calorie deficit, resulting in weight loss, advocates believe the OMAD diet's extended fasting period leads to physiological changes in the body that promote better health, including boosting your metabolism by triggering a process called ketosis, where your body burns stored fat for energy instead of glucose.

Unfortunately, research into the OMAD diet is limited. Most studies have examined its impact on animals , and the primary study with humans involved 11 lean, young people following the OMAD diet for a mere 11 days.

Claims about the OMAD diet typically rely on research into intermittent fasting, rather than on the OMAD diet itself. There is evidence backing the efficacy of intermittent fasting to achieve weight loss.

However, most studies have focused on short-term results only, typically considering the results achieved across 12 weeks or less. Eat Stop Eat is a form of intermittent fasting that involves one or two hour fasting periods each week. During the fasting period, no food is consumed, but non-caloric beverages like water, tea, and black coffee are allowed.

While eating one meal a day can be an effective approach to weight loss and has been associated with improvements in certain health markers, it also raises significant concerns about nutritional balance and long-term sustainability.

The decision to follow this diet should be made carefully, considering personal health circumstances and ideally under the guidance of a healthcare professional. The results of intermittent fasting vary by goal: Improvements in gut health can be seen in a few days.

Weight loss and metabolic benefits may take about a month, and enhancing longevity and overall health generally requires long-term commitment. The length of intermittent fasting depends on the method used. OMAD consists of daily hour fasts with a one-hour eating window. Overnight Fasting typically ranges from 12 to 16 hours daily, often overnight, and Eat Stop Eat features one or two hour fasts per week with normal eating on other days.

Intermittent fasting can vary but the general consensus is to stick to calorie-free drinks like water, black coffee, and herbal teas. Zero-calorie beverages are also an option, but artificial sweeteners are best avoided.

Small amounts of bone broth and diluted apple cider vinegar can be consumed, mainly to manage hunger pangs and provide electrolytes.

: OMAD and weight maintenance

Is Eating One Meal a Day a Safe and Effective Way to Lose Weight?	Any eating pattern that promotes a cycle of food restriction followed by extra food consumption can trigger disordered eating behavior in susceptible people. So if you have a history of an eating disorder, you should probably avoid OMAD. Creating an environment in which you naturally reduce caloric intake is one of the clinical benefits of OMAD. The other side of that coin is that it can be difficult to obtain adequate calories if eating OMAD long-term, without interruption. OMAD can then start to look a lot like chronic caloric restriction. Although chronic caloric restriction helps with initial weight loss, it poses long-term concerns because it tends to lower resting metabolic rate, which makes weight loss very difficult to maintain. Since protein helps you feel full and satisfied, it can be difficult to eat your entire daily requirement in one sitting. If you can eat a oz ribeye plus a couple of fried eggs in one sitting, then it may not be a concern. But if that sounds like a lot to you, then your protein intake may be too low with daily OMAD. If you are trying to consistently remain in ketosis, we recommend restricting net carb intake to less than 20 grams per day. But in general, we also advise that you spread out your carb intake so each meal has no more than 10 grams. With OMAD, you eat only one meal, so you could theoretically eat all 20 grams of carbs in one sitting. While that is still compatible with a keto diet, those who are highly insulin resistant may respond to a gram carb load with a rise in glucose and insulin levels ultimately leading to a decrease in ketone levels. Some find the consistent cycle of no food followed by a large amount of food causes abdominal discomfort and even diarrhea. For those who need to take prescription medications with food more than once per day, OMAD presents a significant hurdle. If this is the case for you, discuss with your healthcare provider if other options exist. If not, then OMAD is likely not safe for you. Some people find it difficult to exercise while fasting. If you are active, this would make following an OMAD pattern challenging. However, we encourage you to at least try fasted exercise. Others are more susceptible to side effects. Feeling a little hungry and a little low in energy are expected. But feeling unwell, extremely fatigued, dizzy, nauseated, or having other severe side effects are abnormal responses to intermittent fasting and OMAD. If you experience any of these severe side effects, OMAD is likely not the best choice for you. You can work with your doctor to determine if any changes like shorter fasting regimens or greater adaptation to fat burning through reduction of dietary carbohydrates could make it an option in the future. The body of literature regarding intermittent fasting and time-restricted eating is growing, seemingly on a weekly basis. The problem is that different studies investigate different protocols. For instance, one study showed that a time-restricted eating pattern can promote weight loss and metabolic health. If is helpful, is better? It might be. If lowering insulin levels and mobilizing fat stores for 14 hours is beneficial, it makes sense that doing it for 23 hours could be even more so. Other studies suggest longer fasting windows have a net benefit, although none capture OMAD eating perfectly. For instance, a pilot study showed that, in obese patients with diabetes, two weeks of eating within a 7-hour window 17 hours of fasting reduced fasting and postprandial blood glucose when compared with eating within the baseline hour window 12 hrs of fasting. While the authors warned about the higher LDL, looking further we see that the total cholesterol-to-HDL ratio remained about the same 3. Because of this uncertainty and the lack of long-term data, we are hesitant to recommend daily OMAD. This is where alternate-day fasting becomes an attractive option. One short-term study compared ADF to daily caloric restriction and found it delivered similar benefits for weight loss and body composition with less of a reduction in adjusted resting metabolic rate. A longer one year study in patients with type 2 diabetes showed that one day of consuming calories followed by two days of normal eating produced HbA1c improvements similar to those observed during chronic caloric restriction. While neither of these studies proves that long-term alternate day fasting is healthy and sustainable, the data are suggestive that OMAD can be incorporated into a healthy, sustainable eating protocol. OMAD appears to be a powerful tool to help with weight loss and metabolic health. That said, we caution against chronic daily use of OMAD for all the reasons outlined above. Instead, for those who may benefit from more pronounced time-restricted eating, using OMAD one to three times per week, on non-consecutive days, could be an effective tool. This is not a science-based protocol with plenty of high-quality evidence, but is instead based on the existing evidence plus clinical experience. Just remember, OMAD is not a license to eat whatever you want. What you eat for your one meal still matters. In a chart review of medical-facility patients, it was found that limited, water-only fasts did not result in any long-term medical complications. However, the studies noted here reference general intermittent fasting or days of water-only fasting. There are not many studies specifically on the risks or benefits of OMAD. The answer is different for everyone. Whether or not OMAD is the right fasting diet is something you should discuss with your primary care provider. When I decided to try OMAD a few months ago I was already doing intermittent fasting, and the idea of losing weight while eating whatever I wanted was appealing. Plus, I liked the idea of challenging myself and pushing through uncomfortable hunger pangs. This is not a diet that can be sustained for a long period of time, therefore, as a Registered Dietitian, I do not endorse this weight loss diet approach. When it comes to dieting, as a rule of thumb, people should be wary of methods and fads that presents itself as an easy fix to a complicated problem. The OMAD diet can be extremely dangerous for children or young adults, people with diabetes or hypoglycemia, obesity, or metabolic rate issues, and it may increase the risk for binge eating. Personally, I would not recommend it as a long-term way of eating for weeks or months at a time. However, one study links eating one or two meals a day to a reduction in BMI , and some people have great results turning OMAD into a lifelong commitment. Besides Herschel Walker mentioned above , another example is Blake Horton, the ripped YouTuber who regularly posts videos of massive meals like chicken taco pizza or a 7-lb burrito of Fruity Pebbles. Like most people, OMAD was a little too difficult for me to do every day. If you want to try fasting but are intimidated by OMAD, you could consider something more manageable for your daily meal plan, like the Diet or the Warrior Diet.

OMAD Diet: Safety, Health Benefits, Risks, and More | Everyday Health	Yes, absolutely. But what I've learned from doing intermittent fasting is that it's a remarkably effective tool for further weight loss. My goal for the next 12 months is to see how far I can take this weight loss and to get really serious about it. In my early 20s, at what I call my "peak condition", it seemed effortless to sustain a healthy weight and athletic physique. I weighed around lbs, which is going to be my target weight, but I'm setting a realistic timeframe. I plan to get there by losing a further 15 to 20lbs of fat in the next days through my OMAD approach and keeping it off. To achieve this, I will adopt a stricter approach to fasting this time, particularly in terms of consistency, to achieve greater results. I fasted for over a year, but there were some cheat days with shorter fasts. For example, I had breakfast on about 10 days. I generally adhered well to the fasting regimen. But, moving forward, I plan to really focus on the quality of what I eat during my eating window, ensuring that my calories are from quality sources, primarily whole foods and protein. That's how I had started. I initially focused on whole food sources and a high-protein diet, which led to my most significant success. Therefore, I plan to continue with this approach.
