It noted that study participants who slept only four hours each, for two nights, had an 18% decrease in leptin, and a 28% increase in ghrelin. Leptin is a hormone that plays a key role in regulating energy intake and energy expenditure. It tells the brain when you've had enough to eat. Ghrelin is the first circulating hormone and its function is to trigger hunger. Lack of sleep produces ghrelin, which stimulates appetite, and also creates less leptin, whose job it is to suppress appetite.
Interestingly, this particular study consisted of healthy, young men, who when sleep deprived, reported a 24% increase in appetite, along with a strong desire for sweets, salty foods, and starchy foods.
Did you know? In the past 40 years, adult Americans have reduced the amount of time they sleep by two hours each night. As sleep time decreased, average weights increased. In 1960, only one in nine adults were obese compared to 2007, when the statistics jumped to nearly one in three!
Could this be the obstacle to your success? If so, let’s try to get more sleep because our wellness journey depends on it.
