|Does BMI Work for Every Body Type? A doctor answers.|
by Kevin Hwang, M.D.
Q. Is it true that the BMI chart works for most body types?
A. A high body-mass index indicates you’re overweight. However, it doesn’t determine whether that weight is due to fat or muscle—or where any extra fat is. Given these limitations, the BMI is still a good indicator for most people.
For people with a BMI between 25 and 35 (overweight to obese), a larger waist (more than 40 inches for men or 35 for women) adds additional risk on top of that associated with the BMI alone. Unfortunately, carrying the extra fat in the hip area doesn't reduce risk; it just doesn’t raise it.

You're correct. The BMI doesn't work as well for height extremes. Why not ask a health care provider or health club to check your body fat with calipers? This is a simple test that bypasses BMI.
People with stomach fat have higher risks of heart disease than those with hip fat. (Apple shape vs. pear). It is thought the fat is of a different nature.
Thanks for your comments.

why does waist play such an issue, at 6'7", 255 I am considered overweight though I question the calculations past 6'2" on the tables. I use to be taped in the military at the neck, chest and waist why not use that method, it seems to be more mathmatically correct. Also the BMI needs to be reworked for those on the extreme outsides of the standard deviation.
bmi is nonsense for most people.

Im 5ft 8 and 11st 11 meaning my BMI is 25.1
This is just in the overweight range, but i have a clear set of abs
My friend is 6ft 2 and 13st 5, meaning he is in the normal weight range, yet he has a beer gut and moobs (sorry m8 :P)
So yeah, it is different for people, but im happy with mine, because it doesnt mean anything, it doesnt go on your CV or stop anything.
BMI is just an indicator
Everyone has some weight they could lose, but that doesnt make us all fat
BMI is wrong!

My BMI says I am overweight. I am a professional bodybuilder and fitness training with six pack abs and striated gluts. My BMI read 27% BF. Way wrong!

Thanks for the comment. You are right that genetics plays a role and that weight loss products don't work long-term.
However, regular exercise and a healthy diet do work. If you regularly exercise for around an hour 5 days a week and include some resistance training, along with eating a healthy diet filled with fruits and vegetables (cutting out junk food), then you will lose weight and become healthier with less risk for medical problems (heart, knee and hip arthritis, diabetes, hight blood pressure) down the road.
BMI is just a general measure, however it does take into account height. Measuring body-fat is better.
