Is BMI Accurate?
BMI provides a useful estimate for most adults, but it does have some limitations because it does not directly measure body fat or muscle mass.
- Athletes may have a higher BMI because of increased muscle mass
- Older adults may have different body compositions
- BMI may not apply equally to every individual
Despite these limitations, BMI remains one of the most widely used health screening tools around the world.
