So one pound of muscle weighs more than one pound of fat?
Or is it “muscle is denser than fat”?
No, it means when someone is laying around, they are losing muscle more than the fat they need to lose.
The goal of losing weight is wrong. The goal should be to lose as much fat as possible. If you exercise, you gain the heavy muscle and some people get upset that no matter how much they exercise, they can’t lose weight because they are gaining muscle.
Don’t worry about what the scale reads. Look at what you look like in the mirror. You might gain weight but your size may decrease.
