Yeah its just too crude a measurement. I think the shorter you are and the larger weight you have, it is more likely the person is fat/obese, but for making any conclusive determination of health, nope. You need more. Even a photo would give the context to show athlete versus lots of body fat.
Its also at this point unnecessary if you want to use a couple numbers to generalize a persons health. I mean in 2023 for example, the average American woman is 5’4” and weighs 161 pounds, meaning the average American woman is overweight, so they may as well just by default start there for all women.
Plus fat takes up more volume than muscle. Think of fat as a one pound bag of feathers, and muscle as a one pound bag of stones. Two identical people, both the same height, weight, and sex. One is fatty, out of shape, over the bmi, and is bigger (larger clothes), the other is muscular, in shape, over the bmi and smaller (smaller clothes). It makes no sense. But leave it to the bureaucrats to screw everything up.
