My best friend can eat as much chocolate as she wants and still wears a size 4. I take one bite and I gain two pounds. What gives?
That skinny broad of a best friend likely has a higher metabolic rate than you do, says Dr. Rosch. Aside from gender (men generally have higher metabolisms), there are two other factors that control how your body uses energy: Age and muscle mass. If your friend isn’t younger than you, then she likely has more muscle and therefore a higher metabolism. “When you have a lot of muscle mass, you have a higher burning furnace that requires more fuel to maintain,” says Rosch. You can beat your friend at her own game by incorporating muscle-building weight-training into your workout.
