Answer 2

Advantages: BMI is a simple and quick way to assess if an individual falls within a healthy weight range. It can help identify individuals who may be at risk for weight-related health issues. Disadvantages: BMI does not account for muscle mass, bone density, or body composition, so it may not accurately reflect an individual's level of health. It also does not consider distribution of fat, which can be a significant factor in assessing health risks.
