Lack of sleep linked to weight gain
People who don’t get enough sleep tend to eat more and gain weight. There’s already a lot of evidence linking insufficient sleep to obesity and a new study focuses on how repeated nights of insufficient sleep affect energy balance.
The researchers report volunteers who slept only five hours a night during a working week gained nearly two pounds, when they had unlimited access to food.
They also ate smaller breakfasts when sleep was restricted but they ate more snacks to the extent that the total calories consumed from snacks was more than the calories in one meal.
