Metabolism describes the amount of calories the body needs while resting.
While you and I say "fast metabolism," scientists use the phrase high "basal metabolic rate," or the amount of calories the body needs while resting. The misconception is that thin people always have a high basal metabolic rate.
It is true that muscle requires more calories than fat. In fact, a pound of fat burns about 10 calories and a pound of muscle burns nearly 30, said Catherine Kotz, who studies how the brain regulates energy balance at the Veterans Affairs Medical Center and the University of Minnesota in Minneapolis.
