Does Muscle Burn More Calories Than Fat?

Short answer: Hell yes it does.

1 pound of muscle burns about 6 calories per hour at rest. 1 pound of fat burns about 2 calories an hour at rest. On average, 1 pound of muscle will burn 144 calories in a 24 hour period. So, the moral of the story is replace that fat with lean muscle and you'll be on your way to building a calorie burning machine!
