About BMI.
Body Mass Index (BMI) is a simple calculation using height and weight. While it doesn't measure body fat directly, it's a useful screening tool for weight categories. Normal BMI ranges vary slightly by age and sex — your ideal BMI may differ based on muscle mass, bone density, and overall body composition.
