The term BMI is often used when discussing the obesity epidemic, but what is BMI?

BMI stands for Body Mass Index. It is a number that shows body weight adjusted for height. BMI can be calculated with simple math using inches and pounds, or meters and kilograms. For adults aged 20 years or older, BMI falls into one of these categories: underweight, normal, overweight, or obese.

Note: BMI for Children and Teens based on gender and age specific charts.
