Body water percentage

Post by pdellorto » Fri Apr 10, 2009 2:24 pm

Someone I know just used a scale that tells him his body water percentage. And his BMI.

This was the first I'd heard of such a thing, I'd only seen the body fat scales. I know the BMI number is basically useless...but neither he or I know what the body water percentage is good for.

He came up as 62.9%; human male average is 60%. Does this number tell us anything important? Is it useful for monitoring body composition in any way? Or will it always float around 60%, so long as he's normally hydrated, and not reflect any changes in fat/muscle/bone rations?

I'm curious. I'm mostly expecting the answer to be "both the BMI and TBW numbers tell you nothing useful" but you never know.

I have a scale that also gives you a water %. Just checked, 64%. Typically I'm between 62-65%. Usually stays very consistent.

I guess, there would be some concern if the number took a big swing. I've never seen it below 60, and if I did I would probably grab a glass of water. I don't pay too much attention to it, and it's the last reading on my scale, after weight, bf%, bone density, then water%. I usually step off before I even get a reading.

My post isn't really any help, but I would also like to learn more about this #.

Some guy came to our TKD school years ago, and used an electronic technique to measure body fat, and his machine also gave a percent body water. I don't remember what my number was, but he was quite concerned that mine was low. I guess that I was just in the habit of not drinking enough. I think it's probably no big deal, except that it might show you that you don't stay as well-hydrated as you should.

Hmm I wasn't aware such a thing existed. http://www.google.com/products?q=%22bod ... p&resnum=1 tons of brands and I've never heard of any of them - anybody ever used one of those?

Interesting article basically claiming they're not useful. Hmm.
