what weighs more fat or muscle
5 lbs. of fat is much bulkier than the 5 lbs. of muscle, but five pounds is still five pounds. Muscle does not weigh more than fat. Fat is bulky and lumpy so if you carry an extra five pounds of fat, you'll be lumpier than with five pounds more muscle. A five pound pile of fat will take up more space (volume) than a five pound pile of muscle; but five pounds is still five pounds.
