I admit most of my weight lost last week was water, although I did lose some fat. I will have to get my body fat measured again to be completely sure. I don't think I lost any muscle - I certainly didn't lose any strength.
As long as I keep lifting hard, I am not going to lose too much muscle mass. I'm only 1 week in.
