Too Little Sleep, Too Much Snacking?


WebMD Health News reports a small study in which researchers have found that people who don’t get enough sleep often indulge in excessive snacking.

Results showed that when bedtimes were restricted to five-and-a-half hours, participants consumed an average of 1,087 calories a day from snacks alone. In contrast, they consumed 866 in calories from snacking when given eight-and-a-half hours to sleep.

My Take?

Readers of this blog, and my book SuperSized Kids: How to protect your child from the obesity threat, know that too little sleep (for infants, children, teens, or adults) is strongly associated with obesity.

Too little sleep increases a hormone that increases appetite, and decreases a hormone that decreases appetite.

To lose weight, one needs not just to exercise more and eat better, but to get more sleep.

That’s one prescription my patients actually enjoy getting.
