About BMI
BMI is a simple index of weight-for-height that is often used to classify underweight, overweight and obesity in adults.
A quick read, not a diagnosis
BMI compares your weight to your height and drops the result into a band — underweight, healthy, overweight or obese. At a glance it's a handy gut-check, which is exactly what it was designed for. What it can't do is tell muscle from fat or notice where you carry weight, both of which matter for actual health. A fit, muscular person can read as "overweight" purely because muscle is dense.
Use the number sensibly
Treat your BMI as the first line of a report rather than the verdict. Pair it with simpler real-world signals — your waist measurement, how your clothes fit, your energy, your routine bloodwork — and you'll get a far truer picture than any single figure provides. We go deeper into reading your result in What Your BMI Does and Doesn't Tell You.
Frequently Asked Questions
Is BMI accurate for everyone?
BMI has limitations. It does not distinguish between muscle mass and fat mass, so athletes and bodybuilders may have a high BMI despite low body fat. It also does not account for age, sex, or where fat is distributed on the body. Always consult a doctor for a comprehensive health assessment.
What is a healthy BMI for Indians?
The standard WHO normal BMI range is 18.5–24.9. However, for South Asians including Indians, some health organisations recommend a target BMI of 18.5–22.9 as the normal range, since metabolic risks appear at lower BMI values compared to Western populations.
How can I reduce my BMI?
BMI can be reduced through a combination of a calorie-controlled healthy diet and regular physical activity. Even a 5–10% reduction in body weight can significantly reduce health risks. Always consult a qualified nutritionist or doctor before starting any weight loss programme.
