It undoubtedly contributes to a better life, but is it true that good sleep aids in weight loss?
Several studies have found that sleep is an excellent ally for building a fit physique and maintaining a diet. There is a close relationship between sleep and the production of hormones that regulate hunger and satiety.
Poor sleep, less than 7–8 hours per night, reduces the production of leptin, the satiety hormone, leading to sudden hunger cravings and, consequently, the accumulation of excess weight.
But there’s more.
Sleep also plays a crucial role in regulating metabolism, the mechanism that transforms ingested food into energy and burns calories.

Why and How Good Sleep Aids in Weight Loss
Helps Reduce Hunger
Those who sleep few hours produce higher levels of cortisol, the stress hormone. It stimulates hunger and promotes spikes in blood sugar levels. If not converted into energy, these sugars transform into fat.
Decreases Appetite
Sleep duration has been linked to the regulation of ghrelin, often referred to as the “hunger hormone.” Ghrelin is released by the stomach and signals hunger to the brain.
Studies have shown that individuals who consistently sleep less tend to have higher levels of ghrelin, leading to increased feelings of hunger.

Quality sleep helps reduce sugar intake and promotes a healthier diet.
This was revealed by a British study conducted by King’s College London and published in the American Journal of Clinical Nutrition.
