Run to Curb Your Appetite


Diabetes Forecast, April 2009

Exercise isn’t just a good way to take your mind off eating; it may curb your appetite, too.

In a study of 11 male college students, researchers found that during a 60-minute run on a treadmill, and for up to two hours afterward, production of the appetite-stimulating hormone ghrelin dropped, while production of the appetite-suppressing hormone peptide YY increased. But when the students lifted weights for 90 minutes, ghrelin levels declined as peptide YY levels remained the same.

The results suggest that when a craving hits, weight watchers are better off going for a jog than pumping iron.

*People with diabetes should check with their doctor before beginning a new exercise plan.
