Why Indian BMI cut-offs are different

Asians develop diabetes & heart disease at lower BMI due to body-fat distribution.
WHO: 18.5–24.9 normal · 25–29.9 overweight · ≥30 obese
Asian-Indian (ICMR): 18–22.9 normal · 23–24.9 overweight · ≥25 obese
Aim for the Indian range for metabolic risk, especially with family history of diabetes/PCOD.

Worked example: what does a BMI of 24 mean for an Indian adult?

A 30-year-old Indian woman, 160 cm and 62 kg, has BMI = 62 ÷ (1.60)² = 24.2 kg/m². By WHO limits that reads 'high normal', but by ICMR Asian-Indian cut-offs she is already overweight (≥23), and her doctor would flag metabolic screening if waist circumference exceeds 80 cm. Losing about 5 kg brings her to 22.3 — comfortably inside the Indian healthy band. Use the calculator above with your own height and weight in kg/cm or lb/ft-in.

Ideal weight by height and age

A quick reality check for Indian adults: the healthy-BMI weight range for 150 cm is 40.5–51.7 kg, for 165 cm it's 49–62.6 kg, and for 180 cm it's 58.3–74.1 kg (using the 18–22.9 kg/m² Indian band). Age itself doesn't change the BMI formula, but muscle mass declines with age — so older adults should pair BMI with waist size and strength checks. For a fuller target see the Ideal Weight Calculator.

How this calculator works

BMI = weight (kg) ÷ height (m)². This tool shows both the WHO international cut-offs and the ICMR/Consensus Statement for Asian-Indian ranges so Indian adults can judge metabolic risk correctly. Everything is computed in your browser — no login, no data stored. Content reviewed and updated for 2026.

Limitation: BMI can over-flag muscular individuals and miss central obesity. Combine with waist circumference (target: <90 cm men, <80 cm women).

Frequently asked questions

What is a healthy BMI for Indian adults?

For Asian Indians the healthy range is 18 to 22.9 kg/m² — lower than WHO's 18.5–24.9 — because Indians face higher metabolic risk at lower BMI. A BMI above 23 is already considered overweight in India.

Is the BMI chart different for Indian women and men?

The BMI formula and cut-offs are the same for Indian men and women, but body-fat distribution differs — women naturally carry more fat at the same BMI, and waist targets differ (<80 cm women, <90 cm men). Both sexes should use the Asian-Indian 18–22.9 healthy band.

How do I calculate BMI manually?

BMI = weight in kg ÷ (height in metres)². Example: 70 kg ÷ (1.75 m)² = 22.9. The calculator above handles kg/cm and lb/ft-in units automatically.

Is BMI accurate for everyone?

No. It underestimates fat in older or sedentary people (sarcopenic obesity) and overestimates it in heavily muscled individuals. Pair it with waist circumference & body fat percent for accuracy.

How do I lower my BMI without losing muscle?

Combine resistance training (3-4x/week) with a protein-rich diet (1.2-1.6 g/kg body weight) and a modest calorie deficit (300-500 kcal/day). Focus on fat loss, not weight loss blindly.

Is BMI different for children?

Yes — children use BMI-for-age percentile charts, not the adult cut-offs on this page. See a paediatrician for accurate assessment of a child below age 18.

What if my BMI is below 18.5?

Underweight is linked with weaker immunity, anaemia, and bone loss. Aim to add 250-500 kcal/day from whole foods (nuts, dairy, dals, chapati, paneer) and include strength training to gain weight.
