What is BMI?
Body Mass Index (BMI) is a simple measure of body fat based on height and weight. It is calculated by dividing weight in kilograms by the square of height in metres.
Why Indian Cutoffs Are Different
Research shows that Indians have higher body fat percentage at lower BMI values compared to Western populations. The Indian Council of Medical Research (ICMR) and several studies recommend lower cutoffs for Indians. Under WHO standards, someone with a BMI of 24 is "normal" — but for an Indian adult, this falls in the "overweight" range and carries increased risk for type 2 diabetes and cardiovascular disease.
BMI Classification (Indian vs WHO)
| Category | Indian Scale | WHO Scale |
|---|---|---|
| Underweight | < 18.5 | < 18.5 |
| Normal | 18.5 – 22.9 | 18.5 – 24.9 |
| Overweight | 23.0 – 24.9 | 25.0 – 29.9 |
| Obese | ≥ 25.0 | ≥ 30.0 |
Limitations of BMI
BMI does not distinguish between muscle and fat mass. Athletes and people with high muscle mass may show a high BMI despite being healthy. It is best used as a screening tool, not a definitive diagnosis. Consult a healthcare professional for personalised advice.
Frequently Asked Questions
What is normal BMI for Indians?
For Indians, a normal BMI is 18.5–22.9. This is lower than the WHO standard of 18.5–24.9 because Indians have higher body fat percentage at lower BMI values.
Why are Indian BMI cutoffs different from WHO?
Studies show that Indians develop obesity-related health risks at lower BMI thresholds compared to Western populations due to differences in body composition and fat distribution.
