Frequently Asked Questions

What are the standard WHO BMI categories?

Underweight is < 18.5; Normal weight is 18.5 – 24.9; Overweight is 25.0 – 29.9; Obese is 30.0 and above.

Does BMI distinguish between muscle mass and fat?

BMI is a general screening metric based purely on weight and height. It does not measure body fat percentage directly, so muscular athletes may have a high BMI without excess fat.
