3. Why is BMI Helpful?

BMI is popular as a method of assessing body weight because it is generally good at predicting a person's risk of weight-related disease. It's easy to measure and can be calculated in the doctor's office. Another advantage of using BMI measurements is that they are easy for people to understand. Although BMI is not always the best way of telling whether a person is a healthy weight, it is generally accurate for the majority of the population.
