Limitations of BMI
While BMI is a widely used and simple tool, it's important to understand its limitations. BMI does not differentiate between muscle and fat. This means that very muscular individuals, such as athletes, may have a high BMI that classifies them as 'overweight' or 'obese' even though their body fat is low. Similarly, it may underestimate body fat in older adults who have lost muscle mass. Therefore, BMI should be used as a general screening tool, not a diagnostic one.
