Today you learned your reading comprehension is ham-grade dogshit. It says the BMI SCALE research was funded by WW, not the BMI metric itself. The difference is that the BMI is a simple mathematical ratio of two measurements and the BMI scale is what ties those ratios to particular interpretations about health markers. There is a fucking difference and you should fucking know better. So much for shitlords being supposedly more knowledgeable and observant.
