I must agree with the criticism of BMI as a diagnostic index. It is easy to tell if a person is - ahem - wide and not very high with a single glance. These elementary parameters can easily be deduced from an image of said person. However, it does not convey that essential ratio of muscle to - ahem - adipose tissue that is the stated reason for its prominence. I suggest an older, but more valid, index that was used in the identification of witches. Simply tie the person's hands behind their back and throw him or her into the deep end of the pool. Time to drowning is the response variable and I am certain that those now chastised for their adipose tissue will vastly prefer it.
