How do you interpret body mass index (BMI) for adults?

Body mass index, or BMI, is used to evaluate body fatness. A BMI of 18.5 to 24.9 is considered normal for an adult. A higher number indicates an increased level of fatness, with a BMI of 25.0 to 29.9 considered overweight. A BMI of 30.0 or more is considered obese. BMI calculation is affected by a person's age, race, gender and muscle mass, so these factors should be considered in the overall assessment. The calculation becomes more and more valid as a person's BMI increases.
