NOW! What if I wanted the muscle to weigh the same as the fat. I don't care if they remain the same size. I just want them to weigh the same. Since the piece of fat weighs one pound, we will have to remove 1/4 pound from the muscle so that it, too, will weigh one pound.
BOTTOM LINE
Muscle is good
Fat is bad....let's move on
