According to WILX, Scientists say the bigger your body, the more calories you're burning. That's because your metabolism has to work more in order to keep the body functioning and provide basic energy.

That's referred to as your basal, or resting metabolic rate.

I'm certainly not an expert when it comes to burning calories or whether my metabolism was working hard enough.

I used to work out at the YMCA many years ago just to stay in shape. My work out would consist of racquetball, volleyball, lifting weights, basketball, and swimming.

Have you ever tried to lose weight and the first 10 or so pounds come off much faster then the rest? That's because as you lose mass, your metabolism doesn't need to work as hard as it did 10 pounds ago.

Several other things come into play, like your body composition.

Lean mass, which includes muscle, burns more calories than fat. So the more muscle you have, the more calories you're burning.
