According to an article I read ages ago even Brad Pitt is classed as "obese" according to the BMI scale. Also a lady I worked with, her 16 year old niece was told she was overweight by her school nurse who was going on BMI, the girl is only a size 10 (US 6) and is 5'6, and as a result of being told she was overweight went on a crash diet.
Apparently the whole of the England rugby squad are also obese
