Frequently asked questions

How is BMI calculated?

BMI = weight in kilograms / (height in metres)². For imperial, BMI = 703 × weight in pounds / (height in inches)². The result is compared against category ranges.

What are the BMI categories?

WHO ranges are underweight below 18.5, normal 18.5–24.9, overweight 25–29.9 and obese 30 or above. Asian-Indian cut-offs flag risk at lower BMI values.

What are the limitations of BMI?

BMI does not distinguish muscle from fat or account for body composition, so athletes may read high. Treat it as a rough screening tool, not a diagnosis.
