About BMI
Body Mass Index (BMI) is a person's weight in kilograms divided by the square of height in meters. BMI screens for weight categories that may lead to health problems, but it doesn't diagnose body fatness or health.
BMI Limitations
- May overestimate body fat in athletes and others with muscular builds
- May underestimate body fat in older persons and others who have lost muscle
- Doesn't account for differences in body composition or fat distribution
