Understanding your BMI
Body Mass Index is a screening tool that helps gauge whether your weight is in a healthy range for your height. It correlates strongly with health outcomes across large populations, but it's not a direct measure of body fat — and it can mislabel athletes, the elderly, and growing teenagers.
