What happens to the body if you don"t eat for 16 hours?

Intermittent fasting: what happens to the body during a 16-hour break from food?

1. The body switches to "internal reserves"

After 12 hours without food, insulin levels begin to drop rapidly, and the body undergoes an amazing transformation - switching from glucose to fat stores as the primary energy source. This metabolic shift triggers active fat-burning processes, which can lead to noticeable weight loss.

2. Autophagy begins - natural cell cleansing

During a prolonged absence of food, a unique process of cellular self-restoration - autophagy - is activated in the body. This natural mechanism helps to eliminate damaged cellular components, acting as an internal cleaning system and maintaining health at the cellular level.

3. Blood sugar levels stabilize

Intermittent fasting has a powerful effect on normalizing blood glucose levels, significantly reducing the risk of developing type 2 diabetes. This effect is particularly pronounced in people with insulin resistance, opening new perspectives in the prevention of metabolic disorders.

4. The constant feeling of hunger disappears

Contrary to common fears, many who practice intermittent fasting note that the obsessive feeling of hunger subsides after just a few days of adapting to the new regimen. Leptin, the hormone responsible for the feeling of satiety, begins to function much more effectively.

5. Brain function improves

Recent scientific research shows that intermittent fasting can stimulate the production of brain-derived neurotrophic factor (BDNF) - a substance that has a beneficial effect on memory, mood, and cognitive functions, literally "rejuvenating" the brain.

Nevertheless, specialists warn: despite the many benefits, this regimen is not suitable for everyone. People with chronic diseases, pregnant women, and those taking certain medications need to consult with a doctor.
