BMI isn’t a good metric, this has been known for a long time.
For example, I’m 45yo/178cm/93kg and am obese by BMI measurement. However, my body fat is 20% (Dexa), VO2 of 50 (lab) & have the aerobic fitness to run a half marathon after work and not care.
I’m not surprised that you need other metrics like hip/waist ratio, measured body fat, visceral fat, etc to better understand the composition of someone’s body and how it might relate to health outcomes like heart disease.
