* "The B.M.I. is a mathematical calculation of a person's weight in kilograms divided by his or her height in meters squared. Since most Americans have no clue what their height is in meters (remember the failed attempt to go metric circa 1976?), it's easiest to determine an index rating by visiting a Web site like that of the National Heart Lung and Blood Institute (www.nhlbisupport.com/bmi), where one can determine their index rating by entering their height in feet and weight in pounds."
* "In 1998, two branches of the National Institutes of Health created new guidelines which divided people into categories: You were "normal" if your index rating was between 18.5 and 24.9; "overweight'' if it was 25 to 29.9; and "obese" if it was 30 or higher."
* "The index also didn't distinguish between body fat and muscle mass, so athletes and bodybuilders like Arnold Schwarzenegger, whose rating was 33 when he was Mr. Universe, were technically obese."
