You're mistaking weight for density. You can't create mass out of nowhere. If you transform fat into muscle, you still have the same amount of the same atoms,

Calories measure energy content, not mass. > If you transform fat into muscle, you still have the same amount of the same atoms No, you don't. > and thus weight the same. Yes, if you trade one pound of fat for one pound of muscle, weight is the same. But since fat has an energy content around 3500kcal/pound and muscle is, IIRC, around 750kcal/pound, that corresponds to more than a 2500kcal calorie deficit with no weight change.
