BMI is indexed to a world-wide average. You are being compared to a Somali as well as a German.

If half of Americans are "overweight" then basic statistic al evaluations dictate that you must re-evaluate your sample base to get rid of bias.

Americans should be compared to their peers i.e. North Americans or first world samples because 98% of the world is overweight compared to Somalis.

V = Pi * r^2 * h

Volume of a cylinder? What does that have to do with BMI?

Ideally it shouldn't be "average" - it should be "healthy". If everyone is a fat ass that doesn't make it healthy. Now, how do you match height to weight without considering body type or body fat percentage? Can't do it.

On the other hand, my doctor could do the scene from Airplane where Johnny says "And Leon's getting larger" for my diagnosis rather than the BMI.

I suspect once tbe progressive democratic communist party of America takes over the government again it will be used to deny medical services to anyone with a higher bmi than the charts indicate it sould be.

Depends upon the location of said “dyed hair”.

I went to a BMI calculator. I am 5’11”. I entered my height and actual weight of 175 pounds. The calculator says my weight is normal. I entered 195 pounds the calculator said that is normal. I entered 145 pounds the calculator said that is normal. When I entered 200 pounds I finally got an abnormal (over weight) reading. The results are all over the place,

I would have to lose about 40 pounds to not be “obese.”

My doctor doesn’t concur with that based on my structure. He thinks I should lose about 35.

He has me confused. So, I just stopped trying.

(I am kidding. I could lose 45 pounds.)

Right, the BMI is a simple metric for tracking body composition trends in populations over time. When used in that way—as a statistical tool—it works just fine. When it’s applied to individuals it just causes confusion.

I suspect you do not need to lose 100 pounds. It’s well known that exercise and diet do not always result in significant weight loss. Your body will fight losing weight. As you diet, your metabolism will decrease making exercise difficult. About the only way diet and exercise will result in significant weight loss is if you’re on a draconian program like in a POW camp.

I’ve had weight loss surgery and it’s been wonderful. I’m down 80 pounds, blood pressure is down forty points (no longer taking 2 bp pills a day), resting heart rate is under 50.

As a lot of medical measures are these days, its a back of the envelope screener. If you are a big person, muscular and wide...they can do caliper tests or even still do the immersion/displacement test.

But, for the most part the key readings are done in total, and a profile is done.

My doc goes though my weight, blood pressure, blood enzymes, blood glucose, and cholesterol and comes up with some sort of index.

My weight and blood pressure haven’t changed much in 40 years—and my blood pressure was always low—so low it hindered me from jobs like flying because they were afraid I would pass out.

It was a curse as a youth—but now at 60 I feel blessed.

Well stated. It’s a telescope, not a magnifying glass, so to speak.

Test: Stand naked in front of a full length mirror.

You will get your answer on whether you are fat/obese or not.

...nearly 3 million people dye yearly worldwide...

I think the last time I dyed anything I was 4 or 5 years old and it involved Easter eggs.
