Question 1

Is BMI accurate for Indians?

Accepted Answer

Standard BMI categories (developed for Western populations) underestimate health risks for Indians. South Asians tend to have higher body fat percentage, more visceral fat, and greater insulin resistance at the same BMI. That's why the WHO Asia-Pacific guidelines use lower cutoffs: normal is 18.5–22.9 (not 24.9) and overweight starts at 23 (not 25). This calculator uses these Asian standards.

Question 2

What is a healthy BMI for Indian women?

Accepted Answer

For Indian women, a healthy BMI is 18.5–22.9 using Asian standards. A BMI of 23–24 (considered 'normal' by Western standards) already puts Indian women in the overweight category with increased metabolic risk. However, BMI doesn't account for muscle mass or body fat distribution — waist circumference is a better predictor of health risk.

Question 3

Why is Asian BMI different from Western BMI?

Accepted Answer

Research shows that South Asians develop type 2 diabetes, cardiovascular disease, and metabolic syndrome at lower BMI values than Caucasians. At a BMI of 25, an Indian person typically has the same health risk as a Caucasian person at BMI 30. The WHO Asia-Pacific guidelines account for this by lowering the overweight threshold from 25 to 23.

Question 4

What should I do if my BMI is high?

Accepted Answer

If your BMI is above 23 (Asian standard), focus on gradual changes: reduce portion sizes (one less roti per meal), increase protein intake, add 30 minutes of daily walking, and reduce oil/ghee in cooking. A calorie deficit of 500 kcal/day leads to ~0.5 kg weight loss per week. Use our Calorie Calculator to find your target.

Question 5

Can BMI be wrong for muscular people?

Accepted Answer

Yes. BMI doesn't distinguish between muscle and fat. A muscular person (e.g., someone who strength trains regularly) may have a high BMI but low body fat. If you exercise regularly and have visible muscle definition, your BMI may overestimate your health risk. In this case, body fat percentage or waist-to-hip ratio are better indicators.

Question 6

What is the ideal weight for my height?

Accepted Answer

Using Asian BMI standards (18.5–22.9), the ideal weight range depends on your height. For example: 160 cm → 47–59 kg, 165 cm → 50–62 kg, 170 cm → 53–66 kg, 175 cm → 57–70 kg. This calculator shows your personalised ideal weight range based on your height.

Question 7

How often should I check my BMI?

Accepted Answer

Check your BMI once a month if you're actively trying to lose or gain weight. Otherwise, every 3–6 months is sufficient. More important than the number itself is the trend — a gradually decreasing BMI over months indicates sustainable progress.

Question 8

Is BMI relevant for children?

Accepted Answer

BMI for children and teens (ages 2–19) uses age-and-sex-specific percentiles rather than fixed cutoffs. A child's BMI is compared to other children of the same age and sex using WHO growth charts. This calculator is designed for adults (15+). For children, consult a paediatrician.
