“The body mass index has long been criticized as a flawed indicator of health. A replacement has been gaining support: the body roundness index.” Article unfortunately doesn’t give the freaking formula for chrissakes; it’s “364.2 − 365.5 × √(1 − [waist circumference in centimeters / 2π]2 / [0.5 × height in centimeters]2), according to the formula developed by Thomas et al.10”
It’s not doctors that need to know. It’s the insurance companies. They wrote the policies that pay doctors based on the BMI metric. Until those policy changes happen nothing will change.
Insurance companies quietly control so much and most people don’t realize it.
