“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”
Height selection on metric side has jumps of up to 3 centimeters lmao. Makes me doubtful about the accuracy since I’ve never before seen that
I’m also pretty skinny and it says my BMI and body fat is great but that I’m too round. I don’t even have belly and it is showing me as quite rotund lol. I think there’s something fucky going on with my measurements or about inputting metric into the calculator.
E: Tried it again and now I’m out of healthy zone for being too lean. Hmm. I’m not sure if I measured wrong or they’re saying I should have a bit of a belly. Which is the sort of medical advice I actually want lol
Too lazy to look, but given 1 inch = 2.54 cm, my guess is the tool is written in inches, and just rounds those values to the nearest whole cm, thus alternating between 2 & 3 cm increments.
