“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”
my main beef is that “too fat” is a wildly varying scale from person to person because everyone stores and processes fat differently. and if you’re “too fat” that may not in fact be your most relevant health concern. my experience with health providers that focus on BMI during intake is that if you’re “overweight” many other health problems will be seen through that lens even if they’re unrelated… in my case, lots of dieting advice, being told to exercise more come to find out decades later I had an undiagnosed nervous/muscular condition. now that it’s treated somewhat, my weight stays pretty much in “normal” BMI with the same or lower activity. I’m kinda pissed it took this long to get treatment for an underlying condition because the ruler said “too fat.”
