BMI is a quick screening tool that compares a person’s weight and height to estimate whether they fall within a healthy weight range.
Why it’s used:
- Helps identify potential health risks like obesity, malnutrition, or cardiovascular issues
- Easy to calculate and widely used in medical assessments
But its limitations:
- Doesn’t consider muscle mass, bone density, or body fat distribution
- Athletes may have high BMI but low body fat
