Understanding BMI

What the numbers mean for your health.

What is BMI?

Body Mass Index (BMI) is a screening tool that estimates body fat based on height and weight. It applies to adult men and women.

Limitations

BMI does not distinguish between muscle and fat. Athletes may have a high BMI but low body fat. Use it as a guide, not a diagnosis.

Healthy Range

A BMI between 18.5 and 24.9 is considered healthy. Staying in this range reduces the risk of heart disease and diabetes.
