I don’t know where people got this notion that bmi doesn’t work or is completely wrong. From some research I had to replicate it’s about 87% (using ARC) accurate on its own to predict metabolic disorders, likelihood of hospitalization, and premature death. But that accuracy goes up when you add measures like waist circumference for women and neck circumference for men.

There are different bmi measures that should be used for different racial groups or sex, but those bmi scales are LOWER not higher.

So, a marathon runner, waterpilo player and shot petter should all strive toward the same BMI? Good to know. Or are the latter two bound to live shorter?

I think you’re being purposely obtuse about this. But bmi norms have ranges that can be 20 to 50lbs depending on your height. For athletes they may fall into the overweight category because of dense muscles. But their doctor would use bmi in conjunction with circumference of the neck/waist or body fat tests. That’s where the other 13% accuracy comes from.

Oh, 100% combined predictive accuracy? I see Nobel somewhere here

Don't be ridiculous. Then again, having worked with physicians and being acquaintances with their typical skills in experiment design, statistics and data reduction, I am not surprised.

If you look at the physique of many shotputters, they are absolutely statistically likely to live shorter.

You conclude that "by looking at their physique", or by looking at actual data?
