A Cape Gazette news report notes that a lack of sleep can be a factor in weight gain during the holiday season.

However, when you get enough sleep, the body releases another hormone called leptin that makes you feel full and tells the body to stop eating. When you feel full, the body is not in crisis mode and you have the ability to be more selective with your food choices, making it easier to eat healthy. This may very well give you the control you need to eat the seasonal treats in moderation and not gorge yourself into an extra waist size or two.
