Q. how much of the 'obesity crisis' is a figment of the over-use of the (often misleading) Body Mass Index (BMI)?
Certainly a shift to look at health-related measures would seem to be a good idea, and would also move the focus towards the health issues & away from a crude focus just on weight... anyone who does any weight training (for health or vanity) will know the BMI doesn't include any allowance for muscle density!
