“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”
Look at it this way, BMI is a cross section of weight and height. I was considered “overweight” for ages because I just had tree trunk thighs from hiking and weightlifting. Like, less than 16% body fat but told I’m ‘overweight’ every time I got weighed.
The ruler was fucking wrong.
Nowadays, I’m much more of a fat fuck so the ruler is right now but only just so… I’m still under 25% when using hydrostatic!
