Will Lack of Sleep Increase Your Weight?

Scientists have long known that lack of sleep is associated with weight gain. One study found that after a night of abbreviated sleep, subjects consumed more than 500 extra calories.

Another study also found that subjects ate significantly more snacks and carbohydrates after a night of only five and a half hours of sleep.

According to the New York Times:

“Some studies pin the blame on hormones, arguing that decreased sleep creates a spike in ghrelin, a hormone that stimulates appetite, and a reduction in leptin, which signals satiety.”
