The BMI standard has a lot of deficiencies, it's not hard to find things wrong with it and its accuracy and propriety can be debated until the cows come home. Nonetheless, it's the standard my Internist, Orthopedic Surgeon(s) and Cardiologist use and on the subject of my health, I do listen to those guys. I don't always like what they have to say, but they're the pros with the educations and the many years of experience.
