Body mass index (BMI) is measure of body fat based on height and weight that applies to both adult men and women. Enter your weight and height and hit the 'Calculate BMI' button.
BMI Categories:
Underweight = Less than 18.5
Normal weight = 18.5 - 24.9
Overweight = 25 - 29.9
Obesity = 30 or greater
Note: BMI is a reliable indicator of total body fat, which is related to the risk of disease and death. The score is valid for both men and women but it does have some limits:
It may overestimate body fat in athletes and others who have a muscular build.
It may underestimate body fat in older persons and others who have lost muscle mass.
