Differences between BMI and body fat percentage

Body mass index (BMI) reflects body weight adjusted for height. Body fat percentage directly calculates relative body composition without considering the height or weight.

Body mass index (BMI) is a number that reflects body weight adjusted for height. Body fat percentage directly calculates relative body composition without considering the height or weight.

Comparing BMI and body fat percentage

A comparison of BMI and body fat percentage:

  • BMI is a rough estimate of body fat.
  • BMI does not differentiate between fat and muscle, only taking into account total body mass.
  • Body fat percentage distinguishes fat from muscle and calculates the percentage of body fat in the body.

From a practical standpoint, it is more difficult to accurately measure body fat percentage.

Importance of understanding both BMI and body fat percentage

Both BMI and body fat percentage are important to monitor for a comprehensive view of health. They provide a good starting point, but should not be used alone to make a health diagnosis. For instance, a person might have a normal BMI but a high body fat percentage, indicating that they are “overfat”.
