Please note that "body mass index" is not terribly useful for
anyone
aside from sedentary populations. Just because it says you're
'overweight' doesn't mean you are, and just because it says
you're
NOT
overweight isn't an automatic reason to relax.

Nonsense. If you fall within the recommended ranges, you know
you're
better off (statistically) than those who don't.

The heavier you are, the more it hurts when you fall and the harder
it
is
to
get up.

My stupidity being said, body mass calculator is often not usefull
only
because of innacuracy.
For instance, I have large bones and have a better than normal
muscle
mass.
When I use the "calculator", I am "fat"
When I use the water displacement, impedance measurement or
professional
pinch test, I am very lean.

BMI is based on what's true for most people, but will overestimate
body
fat in a few (probably less than 2%.) It will even underestimate
body
fat in a few, mainly the elderly. So yes, constitutional
differences
(even those related to ethnicity) can be a factor. A friend whose
BMI
is over 30 is more fat than muscle, even though he exercises. He's
an
example of the average person for whom BMI is a useful tool because
it
tells him how he is doing.



BMI is a general term. I agree with what you say. My point was that
BMI
can be estimated or presented in several different ways, often wrong.

I don't agree it's often wrong, unless you mean it can't attribute the
same percentage of body fat to any two people with the same BMI.

My point is SOLELY how so called BMI is determined. There can be as much
as
30% difference based on how it was determined.

Gotcha. I'm just saying it's a useful tool for *most* people
(including me, with a BMI of 24.7)

Water displacement is the only one that works for all people.

An aqueous solution if there ever was one. ;)


Is that another of those homeopathy cures??

For those who don't want or don't need a fancy system, pinch the stomach and
/ or the side between the thumb and forefinger. If either is over 1" a
problem exists.
