Why BMI Is Misleading, and What to Measure Instead

In this video, board-certified nephrologist and obesity medicine specialist Dr. Sean Hashmi explains where BMI came from, why it still gets used, where it misleads across ethnicity, athletes, and older adults, and which measures give a clearer picture of your health.
