    Hey guys here's a question for the likes of diverscience or msubionerd. What relevance does age have for these electro-impedence devices. I have one that I use with my clients and got to discussing this with another co-worker.
    If I have 2 clients that are physically similar: (ht, wt, gender,)
    but one is about 10 years older than the other, and is in way better shape; why does it score the older person as higher in bodyfat based on age? I know it's factored into the algorythm but why does age matter? Isn't fat, fat regardless of age? Thanks for any clarification on this.
    Mike

    Have you tried entering an arbitrary age and measuring both of your clients? In theory the fat% should be the same, or at least have a smaller gap between the two.

    I think the algorithm makes certain assumptions regarding muscle mass, bone density, and water retention at X age range.

    I've done that with myself. If I put in my age I am about 11% if I put in my same stats at 25 I drop to less than 9%. I'm just curious if there is supposedly more visceral fat as you age or if it's more designed for the masses who tend to be heavier. But thanks for the reply.
