The One Meal A Day Diet (OMAD Diet) – How It Works, Health Benefits, And Safety

Eating one meal a day is a habit that many individuals swear by to lower weight and enhance overall health. The one-meal-per-day diet is also related to OMAD.

Although the things and timing of the meal will change based on individual choice, people following an OMAD diet generally restrict their calorie eating to one meal or a short window of time. The potential health benefits of OMAD are linked to fasting containing calorie consumption during the set period and calorie restriction in general.

The One-Meal-a-Day diet is an excellent version of time-restricted eating. However, unlike periodic fasting which normally allows a 4-8 hour consuming window, the OMAD diet has a one-hour consumption window. Therefore, you fast for the other 23 hours of the day.

Although a various type of intermittent fasting is an effective way to lose weight, the OMAD diet is not recommended by nutrients and can even be harmful to people with specific health problems.

There are different kinds of intermittent fasting practices and various ways to complete OMAD. Examples include having only one meal and doing fast for rest of the day or eating limited food during fast. This kind of diet produces a calorie deficit, which can cause weight loss.

Other health benefits linked to fasting include the possibility to lower heart disease risk factors, lower blood sugar, and lower inflammation.

However, compared to another fasting plan, such as the 16/8 method, which involves 8-hours consuming windows and 16-hour fasting windows, eating only one meal is one of the most extreme methods of intermittent fasting every day. Some popular diets improve eating one meal per day.

For example, when following the warrior diet, a person eats a single meal every day, cycling between a long time of fasting with a short time of energy consumption.

Most people following OMAD choose to only eat dinner, even others choose breakfast or lunch as their one meal.

However, some OMAD enthusiasts do not eat anything consisting of calories during their fasting window and only eat calories during their chosen food, which commonly lasts an hour or so.

You must produce an energy deficit to lose weight. You can do this by increasing the calories to burn or lower calorie expenditure. Calorie limitation, no matter how you get it, will lead to fat loss.

Individuals using the OMAD method are prone to lose weight simply because they are consuming fewer calories than they usually would during a normal eating pattern.

For example, a study about healthy adults found that moderate calorie consumption to 4 hours in the evening leads to especially higher body fat than when eating 3-separate meals in the day.

Research has also shown that periodic fasting, like more fasting like OMAD, is likely to weight loss.

However, it does not seem to be more potent than the old way of calorie restriction like lowering calorie consumption like reducing calorie eating at each meal.

A study that combines 50,660 individual revealed that those who eat 1-2 meals every day has a yearly reduction in the body mass index related to those who eat 3-meals every day. The study also showed that an overnight fast of 18 or more hours was combined with decreased bodyweight, related to shorter fasting time.

However, these weight loss benefits are linked with intermittent fasting in common and not just the OMAD. Additionally, extreme methods of fasting like OMAD may cause side effects that people need to consider like raised hunger and metabolic changes.

Nature has predicted mechanisms for meal scarcity. Because it is much more in the interest of nature that we can then go and search for food to survive, the body raises specific hormone secretion, which also promotes metabolism.

Fasting triggers autophagy, a natural cleansing method that restores broken cell components with new and drains toxins from the body. Accordingly, autophagy is one of the health benefits of fasting.

Since fasting helps to detox, it also prevents diabetes, cancer, liver, and autoimmune diseases. Furthermore, it helps to slow down the again process and better for longevity than the normal 16/8 intermittent fasting.

Scientists have shown that more time fasting promotes the basal metabolic rate a long time back. Hence, that fasting slows down metabolism is a myth. As already given, the body increases hormones like adrenaline and the growth of human hormones during periods of fasting.

Therefore, your body stimulates metabolism to be able to search for food for a longer time. And this raises the ability for fat burning for energy.

Because of the flawed definition of a healthy and western diet, insulin resistance is affecting almost pandemic proportions. Since particularly refined carbohydrates and sugars activate the storage hormone insulin production, astronomically high insulin levels are the result.

The body saves itself from hormonal threat by lowering the insulin sensitivity of the cells. However, insulin resistance refers to that the body requires to secrete even more insulin for induing vital functions. As a result, the risk of chronic ailment dramatically increase like

Alzheimer’s

Parkinson

Diabetes and cancer

Cardiovascular diseases

Metabolic syndrome and obesity

OMAD Benefits to Build Muscle

Opposite to what most people think, fasting does not atrophy the muscles.

An essential reason why our body goes under ketosis is to save muscle mass. Many of the metabolic pathways focus on saving muscle at all costs. The misconception that fasting lower muscle mass increase because if we fast for more time, protein is broken down and changed into glucose. However, this not muscle protein.

However, this is not the protein of muscle. In opposite, the body focuses on defective proteins of the intestinal mucosa, and skin, which need to replace.

Hence, to save lean mass, your body releases the counter-regulatory hormones.

One of this human growth hormones or somatropin. During fasting, the release of the growth hormone reaches peak levels to make sure that you do not lose muscle. Therefore, OMAD saves not only lean mass but also bone mass.

Accordingly, fasting is one of the efficient natural growth hormone activators. In short, fasting is anabolic biohacking. Therefore, exercise, fasting, and fish or meat are effective combinations for building muscles.

They provide the following things to build muscle mass:

Growth hormone

Proteins

Creatine

Healthy fats

In your 23 hours OMAD fasting time, growth hormone is high and the body can stimulate muscle protein more specifically.

Like autophagy, this renewal process builds muscles more robust than before.

 

Improve Memory and Cognition

Fasting is a sign to the body that no food is perceived. Counter to popular thought, your body does not shut down as a result.

For example, it turns on the turbo boost. As a result, the body excites the sensitive nervous system, loosens adrenaline, growth hormone, and cortisol.

In short, the body pushes as much energy as possible into your bloodstream to fuel running food. Hence, adrenaline, cortisol, and growth hormone make us seek food.

Therefore, several individuals report more cognition and focus during fasting.

Accordingly, one research discovered no decrease in activity and cognition in subjects, although they are almost nothing for 2-days.

Furthermore, the primary reason for the productivity drop in the afternoon is the breaking of the fast. Because eating makes the body unwind, the sharpened focus sinks.

Additionally, fasting raises the brain-derived neurotrophic factor, even enhance cognitive function.

Since BDNF is a neural growth hormone, it is responsible for the formation of the neuron in the brain. Therefore, high BDNF levels are linked with more intelligence, memory, and mood. When you release BDNF, your brain can create new nerve connections. For this reason, fasting can increase memory and prevent Parkinson’s and Alzheimer’s disease.
