“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”
I bike and rock climb, I walk long walks and overall in a good shape, not great, not terrible. When the doctors see my bmi without other metrics, they immediately tell me to lose weight and don’t take anything else seriously. I missed very serious illness because of that, every symptom I had was thrown into a pile of “your bmi is bad, lose weight”, until one doctor was smart enough to check on me for real.
BMI is incredibly oversimplified and gives lazy or overworked doctors easy way out of doing their jobs, which kills people.
