Body Mass Index

[quote]Problem is the formula can be flawed if e.g. you have lots of muscle and displace much water but don't have that much fat[/quote]<br />
<br />
Hmm: not heard of it before, but that doesn't sound quite right Nick: if it's done properly, they should be getting two measurements from such an action:<br />
<br />
a) The body volume - from displaced water.<br />
<br />

<br />
Knowing muscle, bone and fat densities, it's then just (!) solving a simultaneous equation to get the answer. I can see room for a few errors, but would agree that - in theory - it should be bloody accurate, if someone knows what they're doing. -
Agreed Death - there shouldn't be a lot of room for error for most people but for seriously fat people they could be waaay off. "The Biggest Loser" show features women as high as 170kg and men as heavy as 195kg without being that tall.<br />
<br />
Also complicating this is that even obese people who can still move under their own power tend to have a fair bit of muscle, because otherwise they wouldn't be able to move at all. The muscle might be marbled like prime beef but its still there. The ultimate problem is, as with BMI, they're going off assumptions of what the [i]average[/i] humans surveyed come out at, and don't necessarily take into account the skeletal structure of a person, which under all that fat is bloody hard to measure even though the density remains the same. -
A quick update, apparently BMI has been adopted by all insurance companies because the reinsurers have adopted it.<br />
<br />
Anyway I am still discussing my case with and they are starting to look at other measures and are considering giving me a separate medical. No guarantees yet though and they are reserving the right to fall back on the BMI as grounds for rejecting me. -
Go in there and challenge any of their execs to a live scrummaging session. That'll see how fit the bastards are <img src='http://www.daimenhutchison.com/invision/public/style_emoticons/<#EMO_DIR#>/smile.png' class='bbc_emoticon' alt=':)' />

here a link for some cool things<br />

I would burn 2137.68 calories if I lay in bed all day doing nothing.<br />
<br />
I am also in the obese range. 31.something. <br />
<br />
Reckon I have a bodyfat percentage of 16.3. based on my weight and waist measurement. That mewasurement is not in the obese category, but in the fitness category. -
33.77 (Obese class 1) even with my recent weight loss <img src='http://www.daimenhutchison.com/invision/public/style_emoticons/<#EMO_DIR#>/smile.png' class='bbc_emoticon' alt=':)' /> At my absolute peak a couple of years back I was nearly 39 <img src='http://www.daimenhutchison.com/invision/public/style_emoticons/<#EMO_DIR#>/blink.png' class='bbc_emoticon' alt=':)' /><br />
<br />
If WHEN I get to my goal weight I'll be 29.83, just short of obese, and probably fitter and stronger than every bastard who designed the BMI <img src='http://www.daimenhutchison.com/invision/public/style_emoticons/<#EMO_DIR#>/laugh.png' class='bbc_emoticon' alt=':)' /> -
We should rename it the Bullshit Mass Indicator <img src='http://www.daimenhutchison.com/invision/public/style_emoticons/<#EMO_DIR#>/smile.png' class='bbc_emoticon' alt=':)' />
