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.


It's as simple as
that.
