Body Mass Index (BMI)

BMI uses a mathematical formula that takes into account both a person's height and weight. BMI equals a person's weight in kilograms divided by height in meters squared. (BMI=kg/m2).

Risk of Associated Disease According to BMI and Waist Size
BMI   Waist less than or equal to
40 in. (men) or
35 in. (women)
Waist greater than
40 in. (men) or
35 in. (women)
18.5 or less Underweight -- N/A
18.5 - 24.9 Normal -- N/A
25.0 - 29.9 Overweight Increased High
30.0 - 34.9 Obese High Very High
35.0 - 39.9 Obese Very High Very High
40 or greater Extremely Obese Extremely High Extremely High

One variable BMI fails to consider is lean body mass. It is possible for a healthy, muscular individual with very low body fat to be classified obese using the BMI formula..
