One of our clients wanted me to write an article on why using BMI is a waste of time. To be honest, I thought BMI had gone the way of blood letting and leeches ( cue Steve Martin SNL skit for those over 45) but, apparently not. Our client is a well built, strong man in his sixties who is being told by his doctor that he is overweight. The article below, although the title references female bodies, does an excellent job of poking holes in the BMI idea.
