In my opinion, comparing a single person's BMI to an index is nearly wrong. For one, if you are an active person who lifts weights, you are NOT AVERAGE... so what is the use of comparing you to AVERAGE people?
BMI really is a silly metric, IMO. BUT, the obesity researchers want it both ways now. They've used BMI for a CENTURY now to track obesity. THEN, on learning that obesity really isn't killing us ... they begin to turn on the metric they've used for a CENTURY now to track obesity.
