According to a sleep study done at the University of Colorado Boulder, scientists found that sleep-deprived people eat more than those who sleep for 8 hours.
Natural hormones produced by the body keep body weight balanced. When those hormones are unbalanced weight gain is the result. Leptin and ghrelin control feelings of hunger and fullness. Leptin tells the body to stop eating while ghrelin stimulates the appetite. Sleep deprivation causes cells to resist insulin. Insulin promotes the release of leptin, so less sleep causes more cravings leading to weight gain.
Sleep is necessary for the body to replenish cortisol which is released during physical or emotional stress and also regulates appetite.
