OMAD and appetite regulation -

Because OMAD is a form of intermittent fasting, the theory is that it comes with many of the same benefits, just with a smaller eating window. These are some of the potential benefits of eating only one meal a day:. One of the biggest benefits of the OMAD diet is simplicity.

The only thing you have to really think about is when to break your fast and then stick to that same schedule on the days you incorporate OMAD. While you can lose weight with any type of calorie restriction, one research review compared intermittent fasting to regular, daily calorie restriction to see the effects on body composition 2.

They found that while types of calorie restriction can lead to weight loss, intermittent fasting may help promote a greater amount of fat loss, while also helping retain lean body mass or lean muscle.

Another small, controlled study with 32 participants found that even when overall calories weren't restricted, eating all calories in one daily meal 3 resulted in greater loss of body fat. In one small study, researchers had pre-diabetic men follow different intermittent fasting schedules 4 , but gave them enough food to maintain their current body weight.

After 5 weeks, the men had better insulin levels, improved insulin sensitivity, and better beta cell response. They also saw improvements in their blood pressure and had decreased oxidative stress levels.

Another small study followed 10 obese men with type 2 diabetes who were currently taking metformin, one of the most popular diabetic medications. After two weeks of fasting, the men had better blood sugar control 5 than when they first started the study.

One study showed that prolonged fasting can increase availability of serotonin 6 —a mood-boosting neurotransmitter—in the brain. It may also boost natural opioid and endocannabinoid production.

Although a large amount of the research on intermittent fasting and longevity has used animals as subjects, the results are promising. As one review points out, research on animals and humans indicates that reducing your food intake through fasting can significantly slow or reverse aging.

In fact, one of the longest-running animal studies focused on prolonged fasting 7 found that rats could increase their lifespan by as much as 80 percent.

However, the effects of fasting also depends on sex, age, overall diet, and genetic factors. If you have Type 1 diabetes, OMAD may not provide enough nutrients to keep your blood sugar levels steady through the day, especially in the initial phase when your body is adjusting to it.

As always, consult with your doctor to determine the right plan for you. And keep in mind that it's meant for adults, not children or young adults. Even though there are no strict rules about when to eat your meal on the OMAD diet, research shows that you may be better off getting all your calories in before the evening.

According to one study, eating calories after 5 p. Instead of jumping right into OMAD, Taz Bhatia, M. The goal is to find a plan that works for you by gradually increasing the duration and frequency of your fasting over the course of several weeks to a month to give your body time to adjust.

Focus on lean proteins, healthy fats, and lots of different types of veggies. This helps balance blood sugar levels and your hunger hormones, which can make it easier to stick to a fasting schedule. While the idea is to eat within an hour and fast for the other 23, your plan can look a little different than that.

The major goal is to stick to one nutritionally-balanced meal per day and eat around the same time daily. The OMAD diet is a more intense form of intermittent fasting that requires you to abstain from eating for 23 hours and get all your calories in a one-hour feeding window.

It appears to offer many of the same health benefits as other forms of intermittent fasting , like weight loss, improved mood, better metabolism, and balanced blood sugar levels.

This can lead to nutrient deficiencies , which can negatively affect your health and can lead to serious risks. Lastly, some people following the OMAD dietary pattern will binge on highly processed, calorie-dense foods, like fast food, pizza, doughnuts, and ice cream, during their one meal.

While these foods can fit into a balanced lifestyle, exclusively eating foods high in added sugar and other unhealthful ingredients will negatively affect your health in the long run. Overall, although there are benefits related to fasting and calorie restriction, research has shown that consuming 2 or 3 meals per day is likely a better option for overall health than eating one meal a day 5.

No matter the type of dietary pattern you choose, your intake should mostly consist of whole, nutrient-dense foods. These foods offer little nutritional value, and eating them too often can lead to weight gain and increased disease risk In the strict OMAD diet, this means complete restriction of calories.

You can still enjoy water and other noncaloric beverages in fasting periods. Again, most healthcare providers do not recommend eating just one meal a day, as it can be detrimental to overall health.

Eating one meal a day is unlikely to give you the calories and nutrients your body needs to thrive unless carefully planned. Choosing to eat within a longer time period may help you increase your nutrient intake. If eating one meal a day, try to make meals as nutrient-dense as possible.

These meals should deliver at least 1, calories, which can be difficult for some to ingest over a normal meal window. If you struggle to take in enough calories in one meal, consider increasing your eating window by an hour or so and splitting your meal into two smaller meals.

This can help you get enough nutrients and calories without becoming overly full. Here are some nutritionally complete meal ideas that are likely to exceed 1, calories, as long as portion sizes are large enough:.

In a day, eating 1, calories is a general minimum. Most adults need much more than that to maintain their weight. Keep in mind that this way of eating is much more difficult for those following specific dietary patterns, like vegan diets or low fat diets , due to the number of calories that must fit into a single meal.

Overall, trying to cram all of your calorie needs into one meal is not necessary no matter what your health goal is.

This dietary pattern is also not sustainable or practical for most people. Although fasting in general — including prolonged fasting — may benefit health in a number of ways, people can reach the same health benefits using much more sustainable methods.
