One reason that a person's BMI is just a rough indicator of their overall health and fitness is that muscle is denser than fat. A pound of muscle is about the size of a tangerine, and a pound of fat is about the size of a small grapefruit. Why does this fact make BMI a less accurate measure of obesity for some people?

• It does not describe a person's shape

• It does not distinguish muscle from fat

• It measures only excess fat, not muscle

• It measures only body weight, not density
