Advantages of BMI

Non-invasive. No need for special equipment or procedures.

Simplicity. Easy to calculate with just height and weight.

Standardization. Allows for comparisons across different populations and studies.

Limitations of BMI

Does not account for muscle mass. Muscular individuals may be classified as overweight or obese.

Distribution of fat. Does not differentiate between fat and muscle or where fat is distributed in the body.

Age and sex variations. May not be accurate for elderly individuals or reflect differences in body composition between men and women.
