If there are any fitness geeks in this forum, I've got a question for you.

I have one of those Tanita scales that estimates your body fat percentage as well as telling your weight. As I consider the body fat issue, I wonder what the normal range of 'lean mass' (non-fat weight) is for me.

My calculations suggest that I've got roughly 100 lbs. of non-fat weight (and more fat weight than I'd like on top of that of course). For a woman of medium build, about 5'4", is that 100 lbs. in the ballpark of normal, or am I light on lean mass?

(One reason I ask this is that probably like a lot of people here, I've done a lot of dieting in the past and heard plenty about how that can catabolize lean tissue too.)

Going for a protein shake now...
