You already know that sleep deprivation contributes to hunger, cravings and weight gain, but new research shows why. It has to do with 2 hormones that regulate appetite: Grehlin, which stimulates hunger and Leptin, which suppresses appetite. I bet you can guess what researchers found. People who slept fewer than 5 hours per night had more ghrelin and less leptin than people who had 8 hours sleep or more.
This makes sleep one of the most important (and painless!) parts of your weight loss efforts.
Sweet dreams!
