How it works
BMI compares your weight with your height: weight (kg) ÷ height (m)². The WHO healthy range is 18.5–24.9, but research on Asian Indians shows higher health risks at lower BMIs, so Indian guidelines suggest 18.5–22.9 as healthy and 23–24.9 as overweight. BMI does not separate muscle from fat, so pair it with your waist measurement or body-fat percentage.
Frequently asked questions
What is a healthy BMI for Indians?
Indian consensus guidelines consider 18.5–22.9 healthy, 23–24.9 overweight and 25 or above obese — lower cut-offs than the global WHO ranges because health risks rise at lower BMIs in South Asians.
Is BMI accurate for athletes?
Not always. Muscle is heavier than fat, so muscular people can show a high BMI while being lean. Use body-fat % or waist-to-height ratio alongside BMI.
How often should I check my BMI?
Once every 2–4 weeks is enough. Weigh yourself at the same time of day, ideally in the morning.
