Understanding Your BMI
Body Mass Index (BMI) is a measure of body fat based on your weight in relation to your height. It provides a general indicator of whether you're at a healthy weight for your height. However, BMI doesn't account for muscle mass, bone density, overall body composition, and racial and sex differences.

Understanding Your BMI
Body Mass Index (BMI) is a simple calculation using a person's height and weight to screen for weight categories that may lead to health problems.
While BMI doesn't directly measure body fat, it correlates with more direct measures of body fat and provides an inexpensive screening method.
BMI Limitations
- Doesn't account for muscle mass (athletes may have high BMI)
- Doesn't consider bone density

- May not be accurate for elderly, children, or pregnant women
- Doesn't differentiate between genders or ethnicities
