HowdyTexas, thanks so much for the compliment. I love my green menu and my new body!
My center is like everyone else's I bet, in that all the counselors work on commission and in my opinion, want to do the least amount of work possible to earn that commission. They are supposed to do a body comp and your measurements on sign-up, two weeks later, and then each month after that. Every single month I have to remind them/ask them to do it. Sometimes they'll at least do the body comp when I remind them, but rarely my measurements - they will almost always tell me they'll write it in my chart to be done next time I come in (hoping I suppose, that another counselor will have to do it), even when I'm the only client there.
I bet what the scale calculates is how much water you're carrying, your bodyfat %, and then the difference of all that and your total weight would be your lean body mass. That would include your muscle, organs, and skeleton. Since your organs and skeleton won't change, then seeing differences in your lean body mass number would indicate changes in muscle.
Anyway, they told me that a typical 50 lb weight loss would see anywhere from 5 to 10 lbs of muscle loss. On their plan they claim you'll only see a 1 to 2 lb muscle loss at the most. And I can personally attest to the validity of their claims - I have lost 50 lbs dieting on my own in the past and could not fit into the same size clothes at the same weights, so my body composition is definitely different.
