Celebrities have popularized all kinds of outlandish eating regimen traits through the years. One of many newest traits amongst celebrities is the “one meal a day” eating regimen (or “Omad”).

Followers of Omad embody Bruce Springsteen and Coldplay frontman Chris Martin. Many proponents of Omad declare it helps them higher handle their weight and hold match.

Omad is actually a extra excessive model of different sorts of fasting diets, equivalent to intermittent fasting and time-restricted consuming. The primary distinction is that as a substitute of solely fasting sure days or solely consuming your meals throughout a particular time window, individuals following Omad eat all their day’s energy in a single single, giant meal.

However whereas supporters of Omad say that following the eating regimen improves many features of well being, we truly know little or no about what impact consuming only one meal a day has on the physique—not to mention if it is secure.

Fasting and well being

Proof supporting using Omad is proscribed. Only a few research have truly checked out Omad itself—and most of those who have had been performed in animals.

As such, a lot of the claims that Omad works are anecdotal. Or they’re primarily based on the idea that if different types of fasting can profit well being, then Omad will too.

Analysis into fasting diets continues to be rising. Some proof signifies that one type of intermittent fasting referred to as the “5:2 eating regimen” (the place an individual eats usually 5 days per week, then 800 energy or much less two days per week) could assist individuals higher handle their weight. Nevertheless, it is no higher than different eating regimen approaches.

Analysis has additionally discovered that time-restricted consuming (the place you eat all of your day’s energy inside a particular window of time) can assist individuals higher handle their weight. And it has different well being advantages equivalent to reducing blood stress.

One assessment examine additionally discovered that many various kinds of fasting (together with intermittent fasting and fasting each different day) can enhance a number of features of metabolism. These embody bettering blood sugar and levels of cholesterol, lowering irritation ranges and serving to individuals higher regulate their urge for food. This, in flip, could assist cut back an individual’s danger of weight problems, kind 2 diabetes and heart problems.

Only one meal

One examine to this point has appeared on the impact of Omad in people. On this examine, individuals got the identical variety of energy to eat every day for the examine’s period. For half of the examine, individuals ate these energy in a single meal, earlier than switching and consuming their day by day energy cut up into three meals per day.

Every meal sample was solely adopted for an 11-day interval—not very lengthy in any respect. The one meal was taken between 5pm and 7pm. Solely 11 individuals accomplished the examine.

When individuals ate only one meal per day, they noticed a better discount of their physique weight and fats mass. Nevertheless, individuals additionally had better reductions in lean mass and bone density when consuming only one meal a day. This might result in decreased muscle perform and better danger of bone fractures if the eating regimen was to be adopted for an extended interval.

Animal research trying on the results of Omad have proven conflicting outcomes, with analysis exhibiting mice who ate one giant meal a day truly gained extra weight in comparison with those that ate a number of meals.

Whereas these outcomes could point out that Omad may have advantages for some features of well being, there’s nonetheless loads we do not find out about it. Will probably be vital for future research to analyze the impact of Omad in a bigger variety of individuals and in different teams of individuals (as this examine solely included lean, younger adults). It would even be vital for research to have a look at the impact of Omad over an extended time period, and to conduct these trials in a real-life setting.

It would even be attention-grabbing to know whether or not the timing of the meal can additional enhance the outcomes and if the dietary profile of the meal makes a distinction.

Different downsides

If somebody is simply having one meal a day then it is going to be fairly troublesome for them to fulfill all their dietary necessities, particularly for vitality, protein, fiber and the important thing nutritional vitamins and minerals. Not getting sufficient of those vital vitamins may result in loss of muscle mass, danger of constipation and poor intestine well being.

Somebody following Omad might want to guarantee they get a very good serving of protein and loads of greens, nuts, seeds and a few fruit and wholegrains throughout their single day by day meal to fulfill these dietary necessities. They may even want a very good serving of dairy to guarantee that they meet their calcium and iodine necessities—or a complement or various in the event that they’re plant-based.

This isn’t a eating regimen that we’d advocate for kids, anybody who’s pregnant, hoping to change into pregnant or breastfeeding and undoubtedly not for an individual who could also be vulnerable to an consuming dysfunction.

It is also vital to notice that whereas this eating regimen may work for celebrities, in addition they have entry to nutritionists, high-quality diets and dietary supplements the place wanted. For many of us, this type of eating regimen might be unsustainable—and doubtlessly dangerous in the long term.
