Ok, so here's a question... the scales that claim to know body fat, water %, etc...how accurate are they? how can this thing on my floor really know what y body fat and water level is just by me standing on it?
Can someone please tell me HOW it works, IF it works, or if it is just a load of crap....

Thank you!!!

    I have one that claims to know all that stuff. I went and got my BF% done and it was off by 17%! LOL! Luckily I have lower body fat than my scale said or I would have passed out!

    This website offers a pretty good explanation.

    more of a guide than anything else, and I believe they use a very small electric current to measure resistance between point to point, hence the bare feet on individual plates....though I am completely willing to bow to somebody with actual knowledge rather than my own guess :)

    my apparently sends a tiny electric signal through the body - the speed it returns, depends on the amount of fat & water percentage. I had to enter my age, hight, sex & something else to my profile, so I guess that's taken into account.

    Yes, I had to program all that in as well, I just keep wondering how accurate it is.....

    Thanks :)
