What is BMI?
Body Mass Index (BMI) is a value derived from the mass (weight) and height of a person. It is a standard widely used internationally to measure body fatness and health status, applicable to most adults aged 18-65.
BMI Formula
Limitations of BMI
While BMI is a useful indicator, it has limitations. It does not distinguish between muscle and fat. Therefore, it may overestimate body fat in athletes or those with a muscular build, and underestimate body fat in older persons or those who have lost muscle.
