What is Body Mass Index?

Body Mass Index (BMI) is an approximate measure of whether someone is overweight or underweight. BMI of a person is calculated by dividing the weight of the person in kilograms by the square of their height in metres. BMI attempts to categorize a person as Normal, Underweight, Overweight or Obese based on the value obtained by attempting to quantify the amount of tissue mass (muscle, fat, and bone) in the individual.

Classification Principal cut-off points Cut-off points for Asians
Normal Range 18.5-24.9 18.5-22.9
Pre-Obese (Overweight) 25.0-29.9 23.0-27.4
Obese Class I 30.0-34.9 27.5-32.4
Obese Class II 35.0-39.9 32.5-37.4
