Jeannie is absolutely right, of course. A pound of muscle is exactly the same as a pound of fat. But where the belief that muscle is heavier than fat came from is based on volume. At equal volumes, muscle is heavier. So if you have a cup (yeah, I know, you can't but body components in cups!) of muscle, it will weigh more than a cup of fat...
