How to DO NOTHING and LOSE WEIGHT - Dr Alan Mandell, DC
Even with the very best diet and fitness routine, if sleep is off, you're wrecked. Between living your life, working, and exercising, you're forgetting to sleep enough. Or maybe, more importantly, you don't realize that sleep is the key to being rewarded for your diet and fitness efforts.
Many people believe that hunger is related to willpower and learning to control the call of your stomach, but that's incorrect. Hunger is controlled by two hormones: leptin and ghrelin. Leptin is a hormone that is produced in your fat cells. The less leptin you produce, the more your stomach feels empty. The more ghrelin you produce, the more you stimulate hunger while also reducing the number of calories you burn (your metabolism) and increasing the amount of fat you store. In other words, you need to control leptin and ghrelin to successfully lose weight, but sleep deprivation makes that nearly impossible. Research published in the Journal of Clinical Endocrinology and Metabolism found that sleeping less than six hours triggers the area of your brain that increases your need for food while also depressing leptin and stimulating ghrelin.
