Every time someone spouts "BMI is bullshit", I return "ok then, what measurement do you use then?" BMI isn't perfect, but it's simple and effective for most people. Yes there see exceptions, but it's probably right unless you KNOW it's wrong. I measure my body fat % with calipers. My BMI is just over 26.  I know I'm at a healthy weight because I'm under 10% fat by a measurement that's more accurate/pertinent than BMI. Hospitals should have an option - like "high BMI fee unless certified healthy body comp by a different test"
