Health professionals have sounded the alarm about the real effects of OMAD on the body. The name comes from “one meal a day” in English, which means “one meal a day”.
The effects of OMAD on the body
Celebrities have popularized all kinds of weird food trends over time. One of the latest trends among celebrities is called “one meal a day” (or “OMAD”).
Celebrities who have adopted OMAD include Bruce Springsteen and Coldplay frontman Chris Martin. Many proponents of this style of eating claim that it helps them manage their weight better and stay in shape.
OMAD is essentially a more extreme version of other types of intermittent fasting. Although proponents of this lifestyle say it improves many aspects of their health, there is very little evidence of the effects on the body. Very few studies of OMAD have been done, and most have been done in animals.
Only one study so far has looked at the effect of OMAD in humans. In this study, participants were given the same number of calories to eat each day for the duration of the study.
For half of the study, participants ate these calories in one meal, before switching and eating their daily calories divided into three meals a day. Each meal pattern was only followed for a period of 11 days. The only meal was taken between 17.00 and 19.00. Only 11 participants completed the study.
When participants ate just one meal a day, they saw a greater reduction in body weight and fat mass. However, participants also had greater reductions in lean mass and bone density when they ate just one meal a day.
This could lead to reduced muscle function and a higher risk of bone fractures if the diet were to be maintained for a longer period of time.
Animal studies looking at the effects of OMAD have shown conflicting results, with research showing that mice that ate just one large meal a day actually gained more weight compared to those that ate multiple meals.
Other disadvantages of OMAD
Other disadvantages of OMAD include the difficulty of meeting all nutritional requirements, particularly for protein, fiber and essential vitamins and minerals. Not getting enough of these important nutrients could lead to muscle loss and poor gut health.
A person following the OMAD will need to make sure they eat a good portion of protein and plenty of vegetables, nuts, seeds, fruits and whole grains during their single daily meal to meet these nutritional requirements.
He will also need a good portion of dairy to ensure he meets his calcium and iodine requirements – or a supplement or alternative if plant-based.
Fasting and health
Some evidence indicates that a form of intermittent fasting known as the “5:2 diet” (where a person eats normally five days a week, then 800 calories or less two days a week) can help people manage their better the weight. However, it is not better than other approaches to nutrition.
Researchers have also found that intermittent fasting can help people manage their weight better. And it has other health benefits, like lowering blood pressure.
A review study also found that many different types of fasting (including intermittent fasting and every other day fasting) can improve several aspects of metabolism.
These include improving blood sugar and cholesterol levels, reducing inflammation levels and helping people better regulate their appetite. This, in turn, can help reduce a person’s risk of obesity, type 2 diabetes, and cardiovascular disease.
