I hate the BMI. Here's why - the more fit you become, the higher your BMI. There is no link between a high BMI and long term health risks. None. Yet lazy doctors and insurance companies go strictly by the BMI - it's ridiculous.
The Cooper Institute (the folks that brought you the 10,000 step studies and more) insist that it's the lack of fitness, not fatness that leads to long term health risks. But who listens?
Julie Deardorff from the Chicago Tribune writes this article stating that the BMI is "seriously flawed". Make a copy of it and bring it with you the next time you see your doctor. Maybe he or she will learn something.
