Idk. At one point I was at 11% body fat and still had BMI over 25. (83kg and 1.82m) I don't think I've ever been BMI < 25.

This is a meme that fails to understand the actual, in practice limitations of BMI. The problem is that it underdiagnoses obesity, not that it overdiagnoses it. The problem isn't the nonexistent horde of lean muscular people with BMI > 25, it's all the clinically obese people with BMI < 30 thinking that yeah they're overweight but it's not that bad, they're not obese.

They should account for the difference between the two to control for comorbidities.

the lancet article is hard to just read and says it is a better predictor.

I imagine there are people who think they are ok, who are not, but I can't tell if it goes the other way.
