Frequently Asked Questions
What is Body Mass Index (BMI)?
Body Mass Index (BMI) is a simple measurement of a person's weight relative to their height. It is calculated by dividing weight in kilograms by the square of height in meters. It serves as a general screening tool to identify possible weight problems for adults.
What are the standard BMI categories?
For adults 20 years and older, BMI is categorized as follows: Underweight: BMI is less than 18.5 | Normal Weight: BMI is 18.5 to 24.9 | Overweight: BMI is 25.0 to 29.9 | Obese: BMI is 30.0 or higher.
Is BMI a perfect measure of body fat?
No, BMI is an indirect estimate and does not measure body fat directly. It cannot distinguish between fat and muscle mass. For example, athletes or bodybuilders with high muscle mass might have a high 'Overweight' or 'Obese' BMI despite having low body fat.
