Final answer:
Body Mass Index (BMI) is a useful tool to identify obesity but does not measure body fat directly. Alternative methods like skinfold thickness measurements and bioelectrical impedance can offer more accurate assessments of body fatness.
Explanation:
Body Mass Index (BMI) is a person's weight in kilograms divided by the square of height in meters. It is a widely used measure for identifying obesity but does not directly measure body fat. Other methods like skinfold thickness measurements, underwater weighing, and bioelectrical impedance can provide more accurate assessments of body fatness, but they may be expensive or require specialized training.
