Sleep is very important to health, however did you know a recent study showed that it also important for your weight. Researchers have found that a sleepless night can impair your decision making relative to the food you eat the next day. Test subjects who were sleep deprived craved unhealthy foods like pizza and doughnuts over better foods such as strawberries, apples and carrots. MRI images of their brains also showed impairments in the regions that governed complex decision making and increased activity in regions that governed rewards. Sleep tight!
