Having trouble losing weight? It could have something to do with your bedtime.

New research from the University of Chicago Medical Center finds people who get adequate sleep lose more fat.

The study in the Annals of Internal Medicine was small, with only 10 participants ages 35 to 49. Those dieting adults who slept about 8 and a half hours lost an average of around 3 pounds.

But those who slept only about 5 and a half hours only lost about a pound and a couple ounces.

Levels of a hormone that triggers hunger spiked as the dieters got less sleep, possibly making them more hungry.

Researchers say sleep is something all dieters should keep in mind when trying to do away with extra fat.
