If I'm not mistaken, the concept of BMI was developed by the life insurance companies, as a justification to charge higher rates for obese people. They had to have some sort of guideline to base a higher rate on, so they developed the BMI. It sounds all very scientific, but really is just a ratio of mass to height, not unlike the old charts of "ideal body weight" for a particular height.
If you apply the math and do yor BMI, you may find out that an extremely healthy person has a high BMI, since his body mass is high. But this is misleading. a high body mass (of LEAN body tissue) is NOT the same as a high body mass compossed of a high percentage of fat tissue. You can compare two individuals, each 5'7" of the same weight. Only one person has 10% body fat and the other has 37% body fat. The BMI will be the same....both are unhealthy.
Bottom line is BMI is a worthless concept. IMHO.
