A healthy BMI for Indians is 18.0–22.9 kg/m², according to the 2009 Indian consensus guidelines. A BMI of 23.0–24.9 counts as overweight and 25 or above as obese, which is lower than the international cut-offs of 25 and 30. These lower limits exist because Indians tend to develop diabetes and heart disease at a lower body weight than many other populations.
Key takeaways
- Indian guidelines classify BMI 18.0–22.9 as normal, 23.0–24.9 as overweight and 25 or more as obese.
- The WHO’s international ranges (normal 18.5–24.9, overweight 25–29.9, obese 30+) can underestimate risk for South Asians.
- Waist size matters too: a waist of more than 90 cm in men or 80 cm in women signals abdominal obesity in Indian guidelines.
- BMI = weight in kg ÷ (height in metres × height in metres).
- BMI is a screening tool, not a diagnosis. It does not separate muscle from fat.
What is a healthy BMI for Indians?
For Indian adults, a healthy BMI is 18.0 to 22.9. This comes from the consensus statement on obesity published by Indian experts in 2009, which lowered the overweight and obesity thresholds for Asian Indians.
The 2009 consensus statement (Misra and colleagues, Journal of the Association of Physicians of India) set out these categories for Asian Indian adults:
- Normal BMI: 18.0–22.9 kg/m²
- Overweight: 23.0–24.9 kg/m²
- Obesity: 25 kg/m² or more
- Abdominal obesity: waist circumference of more than 90 cm in men and more than 80 cm in women
The guidelines were based on evidence that Asian Indians tend to carry more body fat, especially around the abdomen, at the same BMI as white Europeans, and face higher rates of type 2 diabetes and heart disease at lower BMI values.
Why are Asian BMI cut-offs lower than the global standard?
Asian BMI cut-offs are lower because research shows that many Asian populations have a higher risk of diabetes and heart disease at BMI levels the global standard treats as normal. The same BMI can mean more body fat and more risk.
In 2004, a WHO expert consultation published in The Lancet reviewed this evidence for Asian populations. It kept the international BMI categories but recommended additional “public health action points” at BMI 23, 27.5, 32.5 and 37.5. In simple terms, a BMI of 23 or more signals increased risk and 27.5 or more signals high risk for many Asian groups. The consultation also suggested that countries could set their own national cut-offs, which India did in 2009.
The UK’s NHS uses a similar approach: it says people from South Asian, Chinese, other Asian, Middle Eastern, Black African or African-Caribbean backgrounds are at risk of health problems at a slightly lower BMI, and classes 23 to 27.4 as overweight and 27.5 or higher as obese for these groups.
What does the BMI chart for India look like?
The BMI chart for India shifts every category lower than the international chart. The table compares the two.
| Category | Indian consensus guidelines (2009) | WHO international classification |
|---|---|---|
| Underweight | Below 18.0 | Below 18.5 |
| Normal | 18.0–22.9 | 18.5–24.9 |
| Overweight | 23.0–24.9 | 25.0–29.9 |
| Obese | 25.0 and above | 30.0 and above |
| Abdominal obesity (waist) | Men more than 90 cm; women more than 80 cm | Not part of the BMI classification |
So a BMI of 24 would be “normal” on many international calculators but “overweight” by Indian guidelines. If you use an online BMI calculator, check which cut-offs it applies.
How do you calculate your BMI?
BMI is your weight in kilograms divided by your height in metres squared. You only need your weight, your height and a calculator.
The formula
BMI = weight (kg) ÷ [height (m) × height (m)]
A worked example
Take an adult who weighs 70 kg and is 168 cm tall.
- Convert height to metres: 168 cm = 1.68 m.
- Square the height: 1.68 × 1.68 = 2.82.
- Divide weight by this number: 70 ÷ 2.82 = 24.8.
This person’s BMI is about 24.8. On the international chart that is normal, just under 25. By Indian guidelines, it falls in the overweight range (23.0–24.9). To reach a BMI of 22.9 at the same height, they would weigh about 64.6 kg (22.9 × 2.82).
For the most reliable reading, weigh yourself in the morning, in light clothing, and measure height without footwear. You can also get your BMI measured at Spark3Fitness; see our page on BMI (body mass index) for details.
Why does waist circumference matter for Indians?
Waist circumference matters because fat stored around the abdomen is more closely linked to diabetes and heart disease than BMI alone. Many Indians have a “normal” BMI but a large waist, sometimes called the thin-fat pattern.
For waist circumference in India, the 2009 guidelines use 90 cm for men and 80 cm for women as the threshold for abdominal obesity. To measure yours:
- Stand straight and breathe out gently.
- Place a tape measure around your waist, roughly midway between your lowest rib and the top of your hip bone, which is often around the navel.
- Keep the tape snug but not tight, and level all the way round.
Another simple check, recommended by the NHS, is to keep your waist less than half your height. For someone 168 cm tall, that means a waist under 84 cm.
What are the limits of BMI?
BMI is a useful starting point, but it cannot tell muscle from fat, and it does not show where fat is stored. It should be read alongside waist size and other health markers.
BMI can mislead in some cases:
- Muscular people may have a high BMI with low body fat.
- Older adults may have a normal BMI but low muscle mass.
- Pregnant women should not use standard BMI charts.
- Children and teenagers need age- and sex-specific charts, not the adult cut-offs.
If your BMI or waist is above the healthy range, regular exercise and balanced eating can help. Our diet consultation service and training programmes are designed to support gradual, sustainable changes.
When should you check with a doctor first?
See a doctor if your BMI is 25 or above, your waist is above the Indian thresholds, or you have a family history of diabetes or heart disease. They may suggest blood sugar, blood pressure and cholesterol checks.
Also check with your doctor before starting a new exercise or diet plan if you are pregnant, have a medical condition, take regular medicines or have recently lost or gained a lot of weight without trying. This article is general fitness information, not medical advice.

Frequently asked questions
What is a healthy BMI for Indians?
According to the 2009 Indian consensus guidelines, a healthy BMI for Indian adults is 18.0 to 22.9. A BMI of 23.0 to 24.9 is overweight and 25 or above is obese.
Is a BMI of 24 healthy for an Indian?
By Indian guidelines, a BMI of 24 falls in the overweight range, even though international charts would call it normal. It is a sign to check your waist size and lifestyle habits.
What is the Asian BMI cut-off for obesity?
Indian guidelines use 25 or above for obesity. The 2004 WHO expert consultation suggested 27.5 as a public health action point for high risk in Asian populations.
What is a healthy waist size for Indian men and women?
Indian guidelines treat a waist of more than 90 cm in men and more than 80 cm in women as abdominal obesity. Keeping your waist below half your height is another useful check.
Is BMI accurate for everyone?
No. BMI does not separate muscle from fat, so it can be misleading for very muscular people, older adults, pregnant women and children.
