“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

      It’s incorrect, it claims my body fat is 19% when I know for an absolute fact it’s 22%.

          I think interestingly enough it’s inaccurate in the other direction. While BMI is will call people unhealthy if they have a lot of muscles, this will call people healthy if they are like me severely underweight.

          My roundness index claims it’s in the healthy zone while in reality my weight is unhealthy.

              I’m currently receiving treatment for onset osteoporosis caused by malnutrition. Also it’s kinda obvious your weight is probably not healthy when your ribs are sticking out.

                looking it up, BRI ranges from 1 to 16, but somehow there isn’t an accepted definition of underweight
