Telling people being obese isn't unhealthy--not productive

37. because bmi *isn't* "crap". If you are doing a study about weight, BMI is what you use. It's

what most studies since the 80s have used. BMI was then the 'new thing,' supposedly better than height-weight charts.

The alternatives (like immersion tanks to measure body fat %) are very expensive, time-consuming (thus expensive), and the additional info they give doesn't justify the cost. Large scale studies would be prohibitive.

"Obesity" is defined as BMI over 30 and adequately matches what most people would consider normal, overweight, obese for most subjects. Some subjects fall outside that bell curve -- as expected, & as is the case for most things.

BMI is a red herring. People are criticizing the use of BMI because they don't like the results. They didn't criticize it in studies that had different results.

You'd probably be shocked if you knew the details of the studies on which nutrient requirements are based.
