BMI Calculator (Asian-Indian)
Indians develop type-2 diabetes and heart disease at lower BMIs than Caucasians. This calculator uses the IDF / ICMR Asian-Indian thresholds — where overweight starts at BMI 23, not 25 — so you see your real risk.
Elevated risk — most Indians have visceral fat at this BMI.
Asian-Indian vs WHO bands
| Band | WHO BMI | Asian-Indian BMI |
|---|---|---|
| Underweight | < 18.5 | < 18.5 |
| Normal | 18.5–24.9 | 18.5–22.9 |
| Overweight | 25.0–29.9 | 23.0–24.9 |
| Obese (class I) | 30.0–34.9 | 25.0–29.9 |
| Obese (class II) | ≥ 35 | ≥ 30 |
Why Indians need different BMI cut-offs
South Asians have higher body-fat percentage and more central (visceral) fat at the same BMI as Caucasians. Studies consistently show that an Indian with BMI 24 has roughly the same diabetes and cardiovascular risk as a Caucasian with BMI 28-29. Going by WHO thresholds gives Indians a false sense of safety in the “normal” and “overweight” bands.
The Indian Diabetes Federation and ICMR officially recommend the Asia-Pacific BMI bands: ≥ 23 = overweight, ≥ 25 = obese, ≥ 30 = obese class II. Most Indian doctors now use these.
Waist circumference matters more than BMI
Two people can have the same BMI but very different metabolic risk depending on where the fat sits. Indians tend to carry visceral fat around the abdomen. The IDF cut-offs for “central obesity” are ≥ 90 cm waist for men, ≥ 80 cm for women. Above these, diabetes and heart disease risk rises sharply regardless of BMI.
What to do if your BMI is in the overweight band
- Aim to lose 5-10% of your body weight over 6-12 months.
- Cut 200-400 kcal/day from your diet — the easiest swaps are sugar in tea/coffee, biscuits with chai, and one extra chapati per meal.
- Add 150 minutes/week of brisk walking or equivalent.
- Pair carb-counting with the Indian Food Carb Counter — most Indian breakfasts are surprisingly high-carb.
