Frequently Asked Questions
Body Mass Index (BMI) is a measure of body fat based on height and weight. It is calculated by dividing weight in kilograms by the square of height in meters.
BMI categories: Underweight (<18.5), Normal weight (18.5–24.9), Overweight (25–29.9), Obese (≥30). These ranges may vary slightly for different populations.
BMI is a general screening tool and may not accurately reflect body fat for athletes, elderly, or pregnant women. Consult a healthcare provider for a full assessment.
