Some days, eating healthy all the way from your morning smoothie to your dinner quinoa bowl comes naturally—it’s like your body craves veggies and whole foods. Other days? Well, you just want a big brownie. What gives? According to a new study, it could be linked to your sleep habits.
In a new study published in the European Journal of Clinical Nutrition, researchers found that test subjects who slept poorly ate an average of 385 extra calories the next day—and no, those calories weren’t from healthy fats and protein.
Why does your body kick you when your down (you know, metaphorically)? The researchers suggest that not getting enough sleep makes the body seek out a reward—hey, making it to that a.m. meeting on time when you’re exhausted is definitely worth noting—and food is a pretty accessible treat. Plus, other studies suggest that sleep deprivation messes with your hormones—which controls your appetite, the New York Times reports.
The takeaway here is that if you routinely find yourself noshing on food you don’t even really want, it might be worth it to head to bed a little bit earlier. And hey, shopping splurges are a reward too, right?
