Are you having trouble losing weight? Maybe you should get sleep more. Many recent studies have shown a link between lack of sleep and obesity. Poor sleep habits interfere with hormones that control appetite and promote nighttime eating. The hormones leptin and ghrelin are
important appetite regulators. Lack of sleep decreases leptin and increases ghrelin, which boosts appetite and promotes overeating. Also, every extra hour you're awake is another hour you can eat.
University of Michigan researchers speculated that most people eat an extra 118 calories for every hour they remain awake. This adds up to gaining nearly a pound every month. See your doctor if you have problems sleeping; it might help you control your weight.
