What is BMI?

Body Mass Index (BMI) is a widely used tool that estimates body fat based on your height and weight. It’s a quick way to screen for potential weight-related health risks  such as heart disease, diabetes, and more.

However, BMI doesn’t account for muscle mass, age, or body composition. For a comprehensive health evaluation, consult a medical professional. Learn more from theCDC’s BMI Guidelines.
