For example, when a person goes on a low carbohydrate diet they will lose
weight very quickly, there will be fat
loss and water
loss. If you look at the word carbohydrate...the word hydrate is attached to the word. So our scale weights are intimately tied to our carbohydrate consumption. When someone loses 7 lbs in 7 days, it is physiologically impossible for that to be all fat. So how much of that is water, fat, muscle etc..
