⚠️ Health Disclaimer

BMI is a screening tool, not a diagnostic measure. It does not account for muscle mass, bone density, overall body composition, age, gender, or ethnicity. Athletes and individuals with high muscle mass may have a higher BMI that doesn't reflect their actual health status. Always consult with a healthcare provider for a comprehensive health assessment and personalized advice.

Understanding BMI

Body Mass Index (BMI) is a measure of body fat based on height and weight. It's calculated by dividing weight in kilograms by the square of height in meters (kg/m²). BMI provides a simple numeric measure of a person's thickness or thinness, allowing health professionals to discuss weight problems more objectively with their patients.

While BMI is a useful screening tool, it has limitations. It doesn't directly measure body fat and doesn't account for muscle mass, bone density, or distribution of fat. For most people, however, BMI provides a reasonable indicator of body fatness and is used to screen for weight categories that may lead to health problems.
