New research is bolstering how important sleep is for a healthy weight. When you're awake between 10 p.m. and 4 a.m., you're more likely to take in extra calories, says a study from the University of Pennsylvania. People ate an average of 553 more calories when they were kept awake until the early morning. But a lack of sleep affects more than just late-night eating. Next time you're tempted to burn the midnight oil, resist the urge. Here's why:
1. You chow down in the morning.
When you're groggy in the morning, you're more likely to eat more. Sleep-deprived participants reported being hungrier in the morning and ate larger portions at breakfast and for snacks the next day compared to participants who slept 8 hours. Researchers think that just one night of total sleep deprivation prompts you to eat more by boosting ghrelin, a hormone that stimulates your appetite.
