How Sleep Affects Your Weight

Have you ever had a night of insomnia followed by a day when your appetite can not be satisfied?  This is an interesting phenomena that is now being studied at the New York University of Medicine.  As it turns out the production of two key hormones, Ghrelin and Leptin may be influenced by how much or how little we sleep.

Here is the scoop.  Leptin and Ghrelin work in concert to control the feeling of hunger and feeling full.  Ghrelin stimulates appetite and Leptin lets our brain know we are full.  When you are sleep deprived Leptin level become very low in the body.  Conversely, as you can probably guess Ghrelin levels rise so you feel hungry the entire day.

A step in the right direction when you are working on obtaining a healthy weight is to get a good nights sleep.  For some of us that is easier said than done.  Stay tuned for tips on getting a good nights sleep.
