BMI Calculator

BMI or Body Mass Index is a globally acknowledged, scientific method of measuring obesity. Recommended by the WHO (World Health Organization), it is a simple index of weight- for- height, which is used to classify underweight, normal, overweight and obese adults along with their level of associated health risks. It is calculated by dividing the weight in kilograms by the square of an individual’s height in meters. The classification of Underweight, Normal Overweight and Obese according to BMI is given in the table below (Ref: Misra A. Body Composition and the metabolic syndrome in Asian Indians: A saga of multiple adversities. Natl Medical J India 2003;16(1):3-7 )

Classification of adults according to BMI

Though globally a BMI of 25 is accepted as normal, for Asian Indians this value is considered higher because at lower BMI they tend to accumulate higher fat percentage which is the actual cause behind developing various other medical disorders and diseases.

A normal BMI should ideally fall between 18.5 and 22.9. A BMI between 23 and 29.9 is considered overweight and anything above that qualifies as obese.

While an individual may have a normal BMI, he/she may still be at a risk of developing health problems due to excessive abdominal fat deposits around the waist. This condition is quite common amongst Indian citizens. A waist circumference of greater than 80 cm (31.5 inches)in women and greater than 90 cm (35.4 inches)in men indicates a higher waist circumference than the normal limit. Waist Circumference serves as a crucial measure of abdominal or central obesity, which is associated with an increased risk of developing Type II Diabetes, Dyslipidemia, Hypertension and Cardiovascular diseases.

Overweight 23 – 24.9
Pre-obese Overweight 25 – 29.9 Increased
Obese Class I Obese 30.0 – 34.9 Moderate
