So you also agree that studies point that BMI doesn't work very well in diagnostics? Because you're replying the statement with a boldened sentence agreeing with gp.
Or perhaps was the point that it's not true that "it doesn't really mean shit now" since the BMI still has some usefulness at the population level?
That's fair, though I also think it's fair to criticize the use of BMI and acknowledge all of its flaws. Perhaps mr givesofmefucks is just stating this position but with harsher wording.
