What you re really losing is water, glycogen, and muscle. This brings us to the scale s sneakiest attribute. It doesn t just weigh fat. It weighs muscle, bone, water, internal organs and all. Losing muscle is nothing to celebrate.
Muscle is a metabolically active tissue.
The more muscle you have the more calories your body burns, even when you re just sitting around. That s one reason why a fit, active person is able to eat considerably more food than the dieter who is unwittingly destroying muscle tissue. One pound of fat is like a big fluffy, lumpy bunch of feathers, and one pound of muscle is small and valuable like a piece of gold. Obviously, you want to lose the dumpy, bulky feathers and keep the sleek beautiful gold. The problem with the scale is that it doesn t differentiate between the two.
