“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”
Here’s an online calculator

This is giving me body fat percentages that are around double what I get from other methods. Not sure what’s up, but I don’t really believe my 5’8" 150lb ass is 30% body fat
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.
How come there’s a metric button that doesn’t work?
Worked for me.
Drag tried on mobile and PC. Every time drag clicked metric, it reloaded and switched back to imperial.
Hmm, that puts me at BRI of 2.1, and BMI of 35.4
Those both seem incredibly off.
But I do have extra dense bones apparently, which tends to be mostly what screws with my BMI, and my ability to float/swim. But they seem really hard to break, not that I try very hard… but none of them have broken yet. And I’ve been in situations that seem like they should have broken.
Either way, I weigh alot more than I look like I should, not quite “Wolverine getting on a motorbike”, but a bit like that.
Kinda makes me wish those “guess your weight” carnival experts were something I could see in real life, only ever seen it on TV.
