> people rally to annonuce that it’s too conservative That’s a bit of a surprise to me. The most common conplaint I heard was “it’s wrong, but we need to keep it around otherwise there’s no way to compare cross-studies”. We have decades and decades of BMI based classification, and publishing a paper today that needs results from past studies will automatically bind it to BMI. Same on public policies, defining obesity threshold a completely different way would require more politics than most groups are able to tackle. It’s like coming up today with a different way to count nutrients from calories, technical merit won’t make it prevail over the whole world that has been built around calories.
