When people are sleep-deprived, they eat almost 300 calories a day more than when they are well-rested. And ice cream is one of their favorite foods to eat when they're tired, a new study shows. Scientists have known for years that too little shut-eye can lead to weight gain and obesity. So researchers at Columbia University decided to find out whether people actually consume more when they are sleep-deprived vs. well-rested. Findings, reported Wednesday at an American Heart Association meeting in Atlanta:
•Participants consumed an average of 296 calories more when they were sleep-deprived compared with when they were well-rested.
•When women were sleep-deprived they ate an average 329 more calories a day vs. when they were well-rested; men ate 263 more calories.
•Overall, most of the extra calories came from high-fat foods such as ice cream and fast foods.
•When women were sleep-deprived, they ate an average of about 31 more fat grams a day. Men's fat intake didn't climb that much.
