About BMI

Body Mass Index (BMI) is calculated as weight (kg) ÷ height² (m²). It's used as a population-level screening tool to identify potential weight-related health risks.

Limitations

BMI doesn't distinguish between fat and muscle, so athletes may register as "overweight" despite being healthy. It also doesn't account for where fat is distributed in the body. Always discuss weight and health with your doctor.
