(Newser) – You better be sleeping enough or you'll plump up, say scientists: Tiredness and sleep-deprivation may lead to snacking. A new study by the Mayo Clinic found that people who got less sleep than a normal night consumed hundreds more calories the next day compared to people who get a full night's rest, and the fatigued did not appear to burn off the extra calories, reports the Daily Mail.

Researchers split 17 healthy young people into two groups. For eight nights, half of the subjects slept normally and the other half snoozed for an hour and 20 minutes less. The tired group ate an average of 549 additional calories per day. "Sleep deprivation is a growing problem, with 28% of adults now reporting that they get six or fewer hours of sleep per night," says one investigator.
