Why do people keep making this argument? It's a terrible argument. BMI and body fat are extremely strongly correlated. People with a very high BMI are all obese or morbidly obese. And people with a very low BMI are almost all underweight. BMI is a very simple, easy to calculate and useful metric. It works across countries and across time. BMI is just one metric. It doesn't tell you everything and knowing only the BMI…
> People with a very high BMI are all obese or morbidly obese. That is tautological - obesity is defined in terms of BMI. BMI over 30 is obese. Arnold Schwarzenegger is 6'2" and weighed 235lbs at contest (30.2 BMI) and 260lbs in the off season (33.4 BMI). So much for your "all" claim.
I'm far from a genetic outlier, but I go to the gym for 3-4 60-90 minute sessions a week. My program is efficient, I don't take steroids, and my nutrition is decent (but not great). I'm 5'10" and 202 pounds (29 BMI).
I find it disingenuous that people use the top performers as an excuse. There is a middle ground where a modest investment will reap significant returns.
If maintaining the healthy function of my body is skewing my BMI as to be useless, then perhaps BMI is a poor metric.
