Answer:
Provide a smooth surface at the ends of synovial joints
Explanation:
Cartilage is the smooth elastic tissue that covers and protects the ends of the long bones. This structural component is present in nose and ear. Different types of cartilage are hyaline cartilage, articular cartilage and so on.
Articular cartilage may be defined as a type of hyaline cartilage that are present on the articular surfaces of the long bones. Articular cartilage is present in close association of menisci. This cartilage provides the smooth surface to the synovial joints and bathed in the synovial fluid.
I'd say that the doctor would recommend to 1: to start a low-calorie, low-fat diet, 2: devote time to follow a workout plan, and possibly 5: Join a weight-loss support group, but I'm not sure about that one.
The reason the doctor wouldn't recommend 3 is because you're supposed to eat several servings of fruit per day, not once a week, and the reason the doctor wouldn't recommend 4 is because an increase in food consumption would add on to the patients problem of being overweight rather than help it.
