few reasons they suspect.
reason one.Increased food intake appears to be the main mechanism,by which insufficient sleep results in weight gain.
reason two.Voluntary sleep restriction,has been shown to increase snacking.
reason three. according to Eve Van Cauter, director of the Sleep, Metabolism and Health Center at the University of Chicago.
There is no doubt that insufficient sleep promotes hunger and appetite, which can cause excessive food intake resulting in weight gain,
Studies have shown that when people don't get enough sleep they:
• Have increased levels of a hunger hormone called ghrelin and decreased levels of the satiety/fullness hormone called leptin, which could lead to overeating and weight gain.
• Consume about 300 calories a day more than when they are well-rested. Overall, most of the extra calories came from high-fat foods.
• Snack more and do less physical activity.
• Eat more than what is needed to cover the energy cost of staying awake longer, especially at night, which can lead to significant weight gain.
