What is BMI?
Body Mass Index (BMI) is a person's weight in kilograms divided by the square of height in meters. BMI is an inexpensive and easy screening method for weight category—underweight, healthy weight, overweight, and obesity.
BMI does not measure body fat directly, but research has shown that BMI is moderately correlated with more direct measures of body fat. Furthermore, BMI appears to be as strongly correlated with various metabolic and disease outcomes as are these more direct measures of body fatness.
Note: BMI is a screening tool, not a diagnostic of body fatness or health. Consult healthcare professionals for comprehensive health assessment.
