BMI

Body Mass Index

Body Mass Index (BMI) is a simple calculation using height and weight (kg/m²) to categorize body size. While widely used by doctors, BMI has serious limitations—it doesn't distinguish between muscle and fat, ignores body composition, and can misclassify metabolic health. A person can have 'normal' BMI but be metabolically unhealthy, or have high BMI while being metabolically fit. Waist circumference and metabolic markers like insulin sensitivity are often better indicators of health.
