Is BMI accurate for everyone?

BMI is a screening tool, not a diagnostic of body fatness or health. It may not be accurate for athletes with high muscle mass, pregnant women, or older adults, as it does not distinguish between muscle and fat.

A BMI between 18.5 and 24.9 is generally considered to be within the normal or healthy weight range for adults.
