Fitness BootcampBMI Calculator

Your BMI, read the way it should be read for Indian bodies.

Most calculators use the global cutoffs. For people of South Asian origin, health risk starts at a lower BMI, so we show you both and explain the difference.

Your numbers

Sex, height and weight are all you need. Waist is optional, and it makes the result far more useful.

    BMI is a screening number, not a diagnosis. It cannot tell muscle from fat and it does not see where fat is stored. Cutoffs follow the 2009 Indian consensus guidelines and the WHO classification. This is educational, not medical advice.

    Why the Indian cutoffs matter

    Studies across India and the wider South Asian population show that type 2 diabetes, high blood pressure and heart disease begin to rise at a lower BMI than in European populations, partly because more fat is stored around the abdomen at the same weight. That is why Indian guidelines set overweight at 23 and obesity at 25, rather than the WHO's 25 and 30.

    If your BMI is 23 or 24 and a global calculator has told you that you are "normal", it is worth reading it again with the Indian cutoffs, and measuring your waist.

    What BMI cannot tell you

    • MuscleA trained 80 kg person and an untrained 80 kg person get the same BMI. Only body composition separates them.
    • Where fat sitsFat around the organs carries far more risk than fat under the skin. Waist measures this, BMI does not.
    • TrendOne reading is a snapshot. What matters is the direction over months, alongside blood markers.

    Common questions

    What is a healthy BMI for an Indian adult?

    Indian guidelines put the healthy range at 18.0 to 22.9. From 23.0 you are considered overweight and from 25.0 obese. The WHO ranges used by most calculators are 18.5 to 24.9, 25 to 29.9 and 30 and above.

    Why does waist matter more than BMI?

    Waist circumference is a direct measure of abdominal fat, which is the type most linked to metabolic disease. A waist that is more than half your height is a sign of raised risk at any BMI. Indian guidelines also flag a waist above 90 cm for men and 80 cm for women.

    Can BMI be wrong for me?

    Yes, especially if you carry a lot of muscle, are very tall or short, are older, or are pregnant. Treat it as a first screen. Body fat percentage and blood markers tell a more complete story.

    How much weight should I lose per week?

    Around 0.5 to 1 percent of body weight per week is a pace that keeps muscle and is sustainable. Faster loss usually means water and muscle are going too, and it tends to reverse.

    A number is a start. A plan is what changes it.

    At Fitness Bootcamp we measure body composition with BIA and DEXA scans and independent blood panels before and after your stay, so BMI is only the beginning of the picture. You live in for four weeks with structured training, cooked vegetarian meals, recovery and a coach beside you. The result is on paper, and your own doctor can verify it.
