Sleep is brain’s nutrition. Most people need between 7 and 9 hours each night. Insufficient sleep impacts your hunger and fullness hormones, including two called ghrelin and leptin.
Ghrelin signals your brain that it is time to eat. When you’re sleep-deprived, your body makes more ghrelin.
Leptin, on the other hand, cues your brain to put the fork down. When you are not getting enough sleep, leptin levels plummet, signaling your brain to eat more food.
Put the two together, and it is no wonder that sleep deprivation leads to overeating and extra pounds.
Then there’s the cortisol spike that comes from too little sleep. This stress hormone signals your body to conserve energy to fuel your waking hours that means you are more apt to hang on to fat.
Sleep deprivation makes you ‘metabolically groggy’ that means – your body’s ability to process insulin – a hormone needed to change sugar, starches, and other food into energy – goes awry. When your body doesn’t respond properly to insulin, your body has trouble processing fats from your bloodstream, so it ends up storing them as fat.
So it’s not so much that if you sleep, you’ll lose weight, but that too little sleep hampers your metabolism and contributes to weight gain.
