Frequently Asked Questions

What is BMI?

Body Mass Index (BMI) is a measure of body fat based on your weight relative to your height. It applies to adult men and women. BMI = weight (kg) / height (m)².

What are the BMI categories?

Underweight: BMI below 18.5. Normal weight: 18.5 to 24.9. Overweight: 25.0 to 29.9. Obese: 30.0 and above.

Is BMI accurate?

BMI is a useful screening tool but does not directly measure body fat. It may overestimate body fat in athletes and underestimate it in older adults. Consult a healthcare provider for a complete health assessment.
