The One Meal A Day (OMAD) method, as the name suggests, is a diet based on taking daily calories in a single meal. Although this method has become popular in recent years, its origin dates back to much older times. In ancient times, hunter-gatherer societies would fast throughout the day until they found food, and when they finally hunted or found food, they would eat a large meal. This lifestyle has caused the human genome to adapt to specific hunger cycles.

Genetic and Evolutionary Basis of the OMAD Method

Humans are genetically adapted to fasting at regular intervals followed by a single large meal. Our hunter-gatherer ancestors often faced starvation and this has been passed down through generations. This means that our bodies have the ability to adapt to situations where food is not available. This explains why diets such as OMAD can be tolerated by modern humans.

The body has learnt to survive by using its energy reserves during periods of extended meal intervals. Therefore, a diet such as the OMAD method actually works in accordance with the body's natural metabolism.

Health Effects of the OMAD Method

The OMAD method aids weight loss because it greatly limits the daily calorie intake. When you only eat one meal, the body uses its fat stores to maintain energy balance. However, losing weight with OMAD depends on the way you apply the method. If high-calorie, non-nutritious foods are preferred, the weight loss process will be negatively affected.

Whether OMAD is healthy or not is a controversial issue. This method may not be suitable for everyone. For some people, prolonged fasting can lead to side effects such as low energy, headaches and concentration problems. It can also be difficult to get all the nutrients the body needs in a single meal.

OMAD and Today's Lifestyle

Nowadays, eating habits are quite different from those of ancient times. Modern life encourages a pattern in which food is constantly available and frequent small meals are consumed. However, the OMAD method can be an effective method for individuals who are genetically adapted to hunger cycles. However, the sustainability of this dietary pattern and its long-term effects on overall health are still unknown.
