Sounds like an infomercial gimmick, right?

But medical evidence suggests that there are links between sleep and weight. Researchers say that how much you sleep and quite possibility the quality of your sleep may orchestrate hormonal activity tied to your appetite.

According to an article I read on webmd, "Leptin and ghrelin work in a kind of "checks and balances" system to control feelings of hunger and fullness, explains Michael Breus, PhD, a faculty member of the Atlanta School of Sleep Medicine and director of The Sleep Disorders Centers of Southeastern Lung Care in Atlanta. Ghrelin, which is produced in the gastrointestinal tract, stimulates appetite, while leptin, produced in fat cells, sends a signal to the brain when you are full. "

"When you don't get enough sleep, it drives leptin levels down, which means you don't feel as satisfied after you eat. Lack of sleep also causes ghrelin levels to rise, which means your appetite is stimulated, so you want more food," Breus tells WebMD. "

What?!? Makes sense, huh? Think about it. I know for myself, when I am tired I eat more and I don't care about what I am eating either. I just don't feel full and keep eating.

So, maybe that will help motivate you to try to get to bed a little earlier at night. Or at least you may recognize that you might be overeating on days after you have not had good sleep the night before.

I wish I could take a nap right now...
