Researchers found that a critical component to weight control is avoiding sleep deprivation.
"There is no doubt that insufficient sleep promotes hunger and appetite, which can cause excessive food intake resulting in weight gain," Eve Van Cauter, director of the Sleep, Metabolism and Health Center at the University of Chicago, told USA Today. "Our body is not wired for sleep deprivation. The human is the only mammal that does this."
Van Cauter, who has spent 15 years studying the topic, added that sleep deprivation may affect every process in the body.
