Portions and the feeling of fullness: how does sleep schedule affect overeating and appetite regulation?

Lack of sleep or its poor quality has a powerful and destructive impact on a person's ability to control portion sizes and recognize their own body's signals. When the body is sleep-deprived, the endocrine system begins to malfunction, affecting the hormones responsible for appetite and satiety. In particular, the level of the hormone ghrelin, which stimulates hunger, increases significantly, while the level of leptin, which is responsible for appetite suppression and the feeling of fullness, drops sharply.

Under conditions of chronic sleep deprivation, a person experiences a constant craving for high-calorie, fatty, and sweet foods, as the tired brain seeks a quick source of energy to maintain alertness. At the same time, even after a hearty meal, the satiety signal may simply fail to reach the cerebral cortex. As a result, portions increase naturally, a person overeats but does not experience satisfaction from food, which creates a vicious cycle of fatigue and excess weight.

To break this connection and restore normal control over portions through quality sleep, you should follow several recommendations:

Caring for a full night's rest is a fundamental basis for normalizing hormonal balance, reducing evening binge eating, and naturally decreasing portions without a sense of deprivation.
