What is BMI?
Body Mass Index (BMI) is a simple calculation using a person's height and weight. The formula is BMI = kg/m², where kg is a person's weight in kilograms and m² is their height in metres squared.
While BMI doesn't measure body fat directly, it correlates moderately with more direct measures of body fat. It's a useful screening tool to identify potential weight problems in adults.
Important Limitations
BMI is a general screening tool and does not account for muscle mass, bone density, age, sex, or ethnicity. It should not be used as the sole indicator of health. Always consult a healthcare professional for a comprehensive assessment.
