Answer:
Body composition
Step-by-step explanation:
"Body composition" is one of the most reliable indicators of a person's health. It shows the ratio of fat in relation to the body's lean tissue. The "lean tissue" refers to "non-fat mass," such as bones, organs and muscles. It is ideal for a person to have a lower fat percentage in order to be considered healthy.
Having fat in the body is fine because a person's body need it to function properly. However, storing excess fat can be dangerous because it is not metabolically active.
