BMI

Junky said:

Can anyone help me regarding the above (Body Mass Index).
Firstly, what is the formula to work this out?
Secondly, what is a good BMI? Like what should we be aiming for?

Thanks

BMI as a measure of fitness is next to useless.There are lots of BMI
calculators on the net. All you need is your height and weight. BMI says
for a given height you should be a given weight. Which would be great
if all humans were produced through cloning, useless given the diversity
of humans in the world. Body Fat % is more useful, but with
non-professional devices such as body fat scales, cheaper calipers etc,
is useful only as a trending measurement.

Yeah, I agree. I'm BMI 'very obese' and then when the folks doing the
measuring see that on the chart, they laugh and say it doesn't apply to
me. However, AFAIK, the life insurance folks still use it and won't
cover me if I were to apply.

One size never fits all and one measure doesn't either.

BMI is not a reliable indicator of health for someone who has added
muscle from lifting weights. If that's not you, then Google is your
friend and you'll find lots of information on the Internet. Plug in
something like "ideal BMI" and read away.

Weight to height cubed, metric units.

Depends. Good for what ? A good BMI for an endurance cyclist or track athlete
is not a good BMI for a shotputter, hammer thrower or olympic lifter.

If your goal is to look like a bodybuilder, 28-30 should do (assuming you
keep your body fat below 15%).

If your goal is to be competitive as a cyclist or runner, 22-24 (this range
is optimal for power to weight ratio, which is a critical success factor in
these sports).

If you want to be a fashion model, 16-19 (for females...not sure about
males).

If your goal is to reduce your risk of dying, a study of one million
participants was published in the New England Journal of Medicine in
October, '99 (http://content.nejm.org/cgi/content/full/341/15/1097 ). They
found that "the nadir of the curve for body-mass index and mortality was
found at a body-mass index of 23.5 to 24.9 in men and 22.0 to 23.4 in women"
(meaning, BMI's in these ranges had the lowest rates of death in their
study).
