Do nothing and burn more calories? Seems too good to be true. But here's the way to make it so: Go to bed. A study revealed that people had significantly slower metabolisms the morning after a sleepless night.
Slow, Sleepy Metabolisms
In the study, male college students participated in two different sleep experiments. One group got a normal night's sleep -- about 8 hours -- while the other group stayed awake all night. And the morning after, researchers found that the metabolic rate of the all-nighters was about 20% lower during breakfast digestion. Not only that, but also the people who didn't get any sleep had higher blood sugar levels, higher stress hormones, and more hunger-triggering ghrelin in their systems. And, not surprisingly, they felt hungrier the morning after not sleeping.
We know from other research that subpar sleep comes with a greater risk of weight gain. But this study offers insight into some possible reasons why, highlighting the way that sleep affects our metabolic rate -- the rate at which our bodies burn calories -- as well as a whole bunch of body systems linked to energy levels and hormones that can influence our eating habits.
