What is considered a healthy BMI range?

According to the World Health Organization (WHO), a BMI between 18.5 and 24.9 is considered the normal, healthy range for most adults.

Does BMI distinguish between muscle and fat?

BMI does not directly measure muscle mass, bone density, or body fat distribution. Athletes and bodybuilders with high muscle mass may register higher BMI scores without excess body fat.
