Sleep deprivation also affects the body’s other biological functions that can keep weight in check. It’s been found that lack of sleep can disrupt hormone levels and impair metabolism.

Leptin, a hormone that contributes to the perception of satiety or fullness, decreases in people who are sleep deprived while ghrelin, a hormone that , increases. This abnormality in hormone levels can trigger a person to consume more food.
