Sleep Deprivation Feeds Hunger

 New research suggests that a poor night’s sleep will likely make you fatter. The review, by King’s College London, found that those who are sleep deprived consume an average of 385 calories more per day than those who sleep for longer. Researchers said that disruption to the body clock appears to affect the hormone ghrelin which controls hunger and the hormone leptin which disctates feeling of fullness. Other studies have found that sleep deprivation can also result in greater activation of areas in the brain associated with reward when people are exposed to food. The research also found that there was a small shift in what sleep deprived people ate: they had proportionately higher fat and lower protein intakes. Senior study authot Dr. Gerda pot, of King’s College London, said, “The main cause of obesity is an imbalance between calorie intake and expenditure and this study adds to accumulating evidence that sleep deprivation could contribute to this imbalance. So there may be some truth in saying ‘early to bed, early to rise, makes a man healthy and wise.'” (Telegraph)
