If you are wondering why your scale isn’t moving but your close fit different then here is your answer. Muscle is flat out denser than fat. As seen in the photo above 2lbs of muscle is less than half the size of 2lbs of fat. So if your clothes are loser but your scale is not budging it very well could be that you are gaining muscle and losing fat “Fat Muscle Exchange”. The other important fact to remember is that every pound of lean muscle your body develops you burn an extra 50 calories a day eve at rest but every pound of fat you store around 3500 calories. The fact is the more lean muscle you have the easier it is to get lean and stay there.
