Frequently Asked Questions

How is BMI calculated?

BMI = weight (kg) ÷ height (meters) squared. For example, for 70 kg and a height of 1.75 m, BMI = 70 ÷ (1.75 × 1.75) = 22.9.

What is the difference between the Asian and WHO standards?

In the Asian population, health risks increase even at a lower BMI, so Indian guidelines consider overweight starting at 23 and obese starting at 25.

Is BMI always accurate?

No. Athletes or people with more muscle mass may have a higher BMI even with low body fat. Children, pregnant women, and the elderly have different guidelines.
