Frequently Asked Questions
Is BMI an accurate measure of health?
While BMI is a useful screening tool for identifying potential weight problems, it does not directly measure body fat or distinguish between muscle and fat. Athletes or highly muscular individuals might have a high BMI without having excess body fat.
What is considered a normal BMI range?
According to the World Health Organization (WHO), a normal BMI falls between 18.5 and 24.9. Values below 18.5 are considered underweight, 25.0 to 29.9 is overweight, and 30.0 or higher indicates obesity.
