I'm not one to buy into claims that a pill can suppress my appetite or a chocolate shake can keep me full from morning until dinnertime. I prefer natural remedies for feeling full -- like eating healthful foods.

There's another natural way to suppress appetite, says RealAge. It also happens to burn fat, fight disease, strengthen bones, and improve mood. Any guesses?

It's exercise.

The jury still hasn't delivered a final verdict on this one but new research suggests exercise can stall the desire to snack. It worked for a group of overweight folks in one study. After three months of aerobic workouts, participants ate less and dropped body fat too.

There may be something chemical that happens when we exercise that helps increase a blood protein known to curb appetite. The higher the protein (called brain-derived neurotrophic factor or BDNF), the fewer calories people ate and the more weight they lost.

Forget that old saying, "work up an appetite." It could be that the more you work, the less appetite you'll have.
