It’s 3 p.m. on a Tuesday and you’d do anything for a donut… with chocolate filling… and those rainbow sprinkles on top. Are you hungry? Bored? You may just have a case of the “sleep munchies.” According to a recent study published in the journal SLEEP, a lack of zzz’s stokes your appetite just like marijuana might. Seriously! When you don’t get enough shut-eye, your brain lights up with the same chemicals that cause stoners to giggle over Funyuns and chomp on Twinkies.
While sleep deprivation has long been linked to overeating and weight gain, researchers at the University of Chicago were able to link it to endocannabinoids, our bodies’ version of THC, marijuana’s active component. Like THC, this chemical can make you want to eat “super-palatable foods” that are high in fat, sugar and salt, says lead author Erin C. Hanlon, Ph.D., Assistant Professor of Endocrinology at the university’s Sleep, Metabolism and Health Center. In fact, getting just 4.5 hours of sleep could mean 33 percent more endocannabinoids than are present after a restful eight-and-a-half hours of sleep. In the study, that resulted in eating double the amount of fat and 46 percent more calories (despite eating a dinner that met 90 percent of their daily caloric requirements only two hours before the snacking session commenced).
And if you have just one sleepless night, it could influence your food choices the next day. In a Mayo Clinic study, people who cut 80 minutes from their regular sleep schedule ended up eating an extra 549 calories the next day. “If we had enrolled participants that usually slept six to six and a half hours a night, we may have seen different effects,” Hanlon says.
