BMI does not take into account body composition. It treats mass as mass. So, fat and muscle are treated the same in the calculation. A person who is very lean but also very muscular could weight the same as a person that has little muscle mass but has a lot of fat. If these people were the same age and the same height, they would have the same BMI. But some would likely consider the muscular person to be healthier than the person with the large amount of fat. That is why a lot of doctors are moving away from using BMI as the sole means of estimating health. However, it is an easy data point to look at and society prefers simple metrics when it comes to labeling people or marking progress.
