Let's just get something straight here: a kilo of muscle weighs the same as a kilo of fat. It bugs me when people say that muscle "weighs more" than fat. Muscle is a bit denser than fat (1.06 kg/litre versus 0.92 kg/litre), but the difference is 15 - 20%. The main reason muscle looks better is because it doesn't sag or wobble.
