Common Myths
Myth: BMI Measures Body Fat
Two people can have the same BMI, but a different percent body fat. A bodybuilder with a large muscle mass and a low percent body fat may have the same BMI as a person who has more body fat because BMI is calculated using weight and height only.
These men have the same height, weight, and BMI, but may have different percent body fat.

This is a good reminder that BMI is only one piece of a person\'s health profile. It is important to talk with your doctor about other measures and risk factors. (e.g., waist circumference, smoking, physical activity level, and diet.)
Myth: BMI is a diagnostic tool
BMI alone is not diagnostic. It is one of many risk factors for disease and death. As a person\'s BMI increases the risk for many diseases increases as well.
