Frequently Asked Questions
Common questions about BMI and healthy weight in India.
What is BMI? +
BMI (Body Mass Index) is a number calculated from your height and weight. It helps estimate whether your weight falls in a healthy range for your height and is widely used as a first screening tool for weight-related health risks.
What is a healthy BMI for Indians? +
For Indian adults, WHO Asia-Pacific guidelines recommend a normal BMI of 18.5 to 22.9. A BMI of 23 or above is considered overweight, and 25 or above is obese — with lower thresholds than Western standards due to higher metabolic risk in South Asians.
How often should I check my BMI? +
Most adults should check BMI once a month. Avoid daily checks because weight fluctuates naturally. Track trends over weeks and months rather than day-to-day changes for meaningful wellness decisions.
Is BMI accurate? +
BMI is a useful population-level screening tool but does not directly measure body fat, muscle mass or fat distribution. It works well for most adults but should be combined with waist circumference and clinical assessment for a complete picture.
Can athletes have misleading BMI results? +
Yes. Athletes and people with high muscle mass may have a high BMI despite low body fat. In such cases, body fat percentage, waist-to-hip ratio or a DEXA scan gives a more accurate assessment than BMI alone.
How can I improve my BMI? +
Improve BMI through balanced nutrition, regular physical activity (30+ minutes daily), adequate sleep, stress management and consistent habits. Consult a doctor or nutritionist for a personalised plan, especially if BMI is outside the healthy range.
