Is BMI the same for men and women?

The BMI formula is the same for both men and women. However, women naturally tend to have a higher body fat percentage than men at the same BMI score.

Why is the Asian BMI scale different?

Research shows that South and East Asian populations have a higher risk of type 2 diabetes and heart disease at lower BMI levels. Therefore, many health authorities use 23.0 as the overweight threshold for Asians.

What is BMI?

Body Mass Index (BMI) is a numerical value calculated from a person's weight and height. It was developed by Belgian mathematician Adolphe Quetelet in the 19th century and is now used worldwide by doctors, nutritionists, and health organisations including the World Health Organization (WHO).

BMI does not directly measure body fat, but it is a quick and inexpensive screening method to categorise weight status.

BMI Formula — Metric (kg and cm)

BMI = weight (kg) ÷ height (m)²

Height must be converted from centimeters to meters first: divide cm by 100.

BMI Categories (WHO Standard)

BMI Range	Category	Health Risk
Below 18.5	Underweight	Nutritional deficiency, osteoporosis
18.5 – 24.9	Normal weight	Lowest risk
25.0 – 29.9	Overweight	Increased risk of chronic disease
30.0 and above	Obese	High risk
