Divide your weight in pounds by that number.
Multiply that by 703.
Or you could let the National Heart, Lung and Blood Institute's website do the work for you at www.nhlbisupport.com/bmi.
Standard weight categories are based on BMI measurements:
* Underweight = BMI less than 18.5
* Normal weight = 18.5-24.9
* Overweight = 25-29.9
* Obese = 30 and above
Though the BMI provides important information, the institute strongly believes that waist circumference -- a measure of abdominal fat -- should be considered too. A high waist circumference is associated with an increased risk of diabetes, high blood pressure and cardiovascular disease, particularly in people who fall into the "overweight" category.
