LACK OF SLEEP MAKES YOU FAT

LACK OF SLEEP MAKES YOU FAT – Have you noticed that when you get a crappy night of sleep you tend to eat more the next day? It’s not in your mind. A meta-analysis published in the European Journal of Clinical Nutrition found that when people don’t get enough sleep, they eat around 385 more calories the following day. This is called “partial sleep deprivation.” You slept, but only about 4-5 hours.

WHAT CAUSES THIS? Partial sleep deprivation results in greater activation of areas in the brain associated with reward. Disruption of the internal body clock also affects your regulation of leptin (the satiety hormone) and ghrelin (the hunger hormone). And get this, lack of sleep gives you the munchies like weed. Erin Hanlon, PhD, notes: “Sleep restriction boosts a signal that may increase the hedonic aspect of food intake. It seems to augment the endocannabinoid system, the same system targeted by the active ingredient of marijuana, to enhance the desire for food intake.”

Other studies have concluded that when healthy young men sleep 5 hours or less per night for a week, their testosterone levels take a dive. Generally that means less muscle, less energy and more body fat over time. Five hours of sleep per night decreased subjects’ T-levels by 10-15% in one study, and these guys were in their early 20’s.
