BMI calculator, read the Indian way.
Your height and your weight, scored against the ICMR cut-offs used for Indian adults rather than the international ones. The difference is not academic — it moves the healthy line down by two whole points.
What BMI actually measures
Body mass index is your weight divided by the square of your height. That is the entire calculation — it was devised in the 1830s by a Belgian statistician studying populations, not patients, and it has never known anything about your body beyond those two numbers.
It survives because it is cheap, repeatable and correlates well with health outcomes across large groups. It fails when it is used as a verdict on one person, which is exactly how most people encounter it.
Why we do not use the WHO numbers
The familiar 25 and 30 thresholds were fitted to European and North American populations. South Asians, at the same BMI, carry more fat and less muscle, and store more of that fat viscerally — around the liver and pancreas rather than under the skin. The result is that type 2 diabetes and heart disease arrive at BMI values the international scale calls normal.
Shipping the WHO bands to a Pune audience would tell people at real risk that they are fine. On a site that runs diabetes reversal and PCOD programmes, that is not a rounding error — it is telling the exact person who needs to hear something that there is nothing to hear.
Questions people ask
Why are the Indian BMI ranges different?
+
Indians carry more body fat, and more of it around the organs, at any given BMI than European populations — and develop insulin resistance and cardiometabolic disease at lower BMI values. Indian guidance therefore treats 23 as the top of the healthy range and 25 as obesity, where the international scale uses 25 and 30. A BMI of 24 is 'healthy' on the WHO scale and 'overweight' here. For a Pune audience the lower cut-off is the honest one.
What is a healthy BMI for an Indian adult?
+
18.5 to 22.9. Below 18.5 is underweight, 23 to 24.9 is overweight, and 25 and above is treated as obese. These come from the WHO Expert Consultation on Asian populations (Lancet, 2004) and the Indian consensus statement on obesity, and are what ICMR uses.
Is BMI reliable?
+
For a population, yes. For an individual, only roughly. BMI cannot tell muscle from fat, so a lifter can read 'overweight' with very little body fat, and someone sedentary can read 'healthy' while carrying a lot. It also says nothing about where fat sits, and belly fat is the kind that matters most for metabolic risk. Use it as a first screen, then measure your waist or your body fat.
What should I measure instead?
+
Waist circumference is the single most useful addition, because it picks up the visceral fat BMI misses. Indian guidance flags 90 cm for men and 80 cm for women. Body fat percentage from a tape measure is the next step up.
Does BMI work for children or during pregnancy?
+
No. Children need age-and-sex percentile charts rather than adult cut-offs, and BMI is not interpretable during pregnancy. This calculator is for non-pregnant adults aged 18 and over.
