I don’t apologize for using BMI as a measure of “fatness”, either.
Most people are not Jay Cutler. I realize there is a subset of people, maybe about 0.01% percent of the population, to whom BMI is not a good measure of fatness.
That does not mean it is something to be ignored for the rest of us, though. For the lot of people out there who are not professional athletes or Mr. Olympia level body builders, BMI is an accurate and viable tool.
