🧮 What Is the Body Mass Indicator (BMI)?
BMI is a simple, yet powerful metric that compares your weight to your height. It helps determine whether you’re underweight, within a healthy range, overweight, or obese. While it doesn’t measure body fat directly, it is widely used by health professionals as a general indicator of health risk.
