Hitting the hay late and cutting sleep short could pack on pounds, says a study in the journal Sleep, which found that non-obese adults who slept from 4–8 a.m. for five straight nights gained more weight than those who slept from 10 p.m. to 8 a.m. (10 hours— nice), and were likelier to crave higher-fat snacks (we’re looking at you, potato chips).
“Sleep deprivation may lead to changes in hormones like ghrelin, which signals hunger,” says study author Andrea Spaeth. Something to keep in mind the next time you’re tempted by 2 a.m. Raymond reruns.
