How is appetite affected by our sleep quality ? | Peter Attia, M.D. & Matthew Walker, Ph.D.

Well SupportedSleep deprivation decreases the satiety signal (leptin) and increases the hunger signal (ghrelin), resulting in increased caloric intake.

Partially SupportedHuman beings are unique in deliberately depriving themselves of sleep for no apparent reason, unlike other species.

Well SupportedSleep deprivation contributes to obesity by increasing hunger, reducing satiety, decreasing motivation for exercise, and burning fewer calories.

Well SupportedSleep deprivation signals starvation to the brain, triggering hormonal changes that increase appetite and reduce satiety.
