Eating one meal a day is used by many people to lose weight and improve health, this is also known as OMAD. While the composition and timing of meals will vary depending on personal preference, people following the OMAD diet often restrict calories to a single meal or a short period of time.

There are many types of intermittent fasting practices and many ways to do OMAD. Examples include eating only one meal a day and fasting during the day or eating one meal and eating a limited amount of food during the fast. This type of diet creates a calorie deficit, which can lead to weight loss. Some other health benefits associated with fasting include: the ability to reduce heart disease risk factors, lower blood sugar, and reduce inflammation.
However, when comparing this method with other fasting regimens, such as the 16/8 method, which eats only one meal per day, one of the most draconian intermittent fasting practices.
Some popular diets recommend eating one meal a day. For example, when following the Warrior Diet, a person eats a single meal a day, cycling between long periods of fasting with short periods of energy consumption.
People who follow the OMAD once-a-day diet usually only eat dinner, although others choose breakfast or lunch. Some versions of the one meal a day model allow for one or two snacks in addition to a meal.

However, this method does not appear to be more effective than any traditional method of calorie restriction, such as reducing the number of calories consumed at each meal. An analysis that applied this method to 50,660 people found that those who consumed 1 or 2 meals per day experienced a yearly decrease in body mass index (BMI) compared with those who consumed 3 meals per day. Research has also shown that overnight fasting for 18 hours or more is associated with weight loss, compared with shorter periods of fasting.

Additionally, fasting may have benefits for nervous system health. This method slows down neurodegeneration and increases lifespan, according to animal studies. However, while these potential benefits are promising, it is important to note that these benefits are associated with fasting. In fact, some studies suggest that the OMAD pattern may be more harmful to health than other less restrictive methods of fasting.
Although research has linked fasting and calorie restriction to many health benefits, some evidence suggests that restricting too much may include eating just one meal a day more often than not. profit.
Other studies have also shown that eating one meal a day can increase fasting blood sugar, slow the body's response to insulin, and increase levels of the appetite-stimulating hormone ghrelin, compared to eating three. meals every day.
Furthermore, restricting calories to only one meal a day may increase the risk of hypoglycemia or low blood sugar, especially in people with diabetes. In addition to these potential side effects, eating one meal a day can lead to symptoms including: nausea, dizziness, irritability, low energy, constipation.
