What is a normal BMI for Indians?+
For Indians and South Asians, the WHO recommends lower BMI thresholds: Normal: 18.5–22.9, Overweight: 23–24.9, Obese Class I: 25–29.9, Obese Class II: 30+. Indians tend to have higher body fat percentage at lower BMI compared to Caucasians, so 23 is considered the overweight threshold for Indians vs 25 for Western populations.
How is BMI calculated?+
BMI = Weight (kg) ÷ Height² (m²). Example: Weight = 70 kg, Height = 170 cm (1.70 m). BMI = 70 ÷ (1.70 × 1.70) = 70 ÷ 2.89 = 24.2 (Normal weight). For imperial units: BMI = 703 × Weight (lbs) ÷ Height² (inches²).
Is BMI an accurate measure of health?+
BMI is a useful screening tool but has limitations: It doesn't distinguish between muscle and fat (athletes may have high BMI but low fat), doesn't account for fat distribution (abdominal fat is more dangerous), and may not be accurate for elderly people who lose muscle mass. For better assessment, use BMI along with waist circumference and body fat percentage.
What is the ideal BMI for a woman in India?+
For Indian women, the ideal BMI range is 18.5–22.9. A BMI between 23–24.9 indicates overweight. However, BMI doesn't account for muscle mass or pregnancy. Pregnant women should not use BMI as a health indicator. Consult a doctor for personalized assessment.
What is morbid obesity BMI?+
Morbid obesity (Class III obesity) is defined as BMI ≥ 40. It significantly increases risk of type 2 diabetes, heart disease, sleep apnea, joint problems, and certain cancers. For Indians, some experts consider BMI ≥ 37.5 as morbid obesity. Bariatric surgery is typically considered for BMI ≥ 40 or BMI ≥ 35 with serious comorbidities.
What BMI is considered underweight?+
BMI below 18.5 is classified as underweight. Being underweight increases risks of malnutrition, weakened immune system, osteoporosis, and fertility issues. In India, underweight is a significant public health concern, particularly among women of reproductive age. Consult a nutritionist if your BMI is below 18.5.
