Lack of Sleep Spurs Overeating
The appeal of a decadent breakfast following a poor night’s sleep may not stem from a lack of willpower; it could be hormonal. A study found that men who, for four days in a row, went to bed at 1 a.m. and got up at 5 a.m. had a spike in levels of ghrelin, a hunger-stimulating hormone. And sleep-starved women had a shortage of GLP-1, a hormone that promotes feelings of satisfaction after eating. So inadequate sleep led the men to be hungry and the women to be unsatisfied, which spells overeating for both sexes. The solution? A good night’s rest.
