Indian vs Western BMI Standards
The WHO Asia-Pacific Task Force set separate cutoffs for South Asians because Indians develop metabolic risk (diabetes, heart disease) at lower BMI values than Western populations.
| Category | Indian BMI | Western BMI | Metabolic Risk |
|---|---|---|---|
| Underweight | Below 18.5 | Below 18.5 | Malnutrition risk |
| Normal | 18.5–22.9 | 18.5–24.9 | Low risk |
| Overweight | 23.0–27.4 | 25.0–29.9 | Moderate risk |
| Obese | 27.5+ | 30.0+ | High risk |
Frequently Asked Questions
Standard BMI is less accurate for Indians because it was calibrated on Western populations. Indians carry more body fat at the same BMI and develop metabolic disease at lower BMIs. Use WHO Asia-Pacific cutoffs (this calculator).
18.5–22.9 is normal. 23.0–27.4 is overweight. 27.5+ is obese for Indian adult males per WHO Asia-Pacific 2004 guidelines. Women use the same cutoffs.
Six-pack abs typically appear at BMI 19–21 for Indian males (body fat 8–13%). For Indian females, BMI 18–20 (body fat 16–20%). Use our Body Fat Calculator for a more accurate estimate.
