A 1200-Calorie Diet and Exercise Are Prescribed for a Patient

A 1200-calorie diet and exercise are prescribed for a patient with newly diagnosed type 2 diabetes. The patient tells the nurse, "I hate to exercise! Can't I just follow the diet to keep my glucose under control?" The nurse teaches the patient that the major purpose of exercise for diabetics is to

A) increase energy and sense of well-being, which will help with body image.
B) facilitate weight loss, which will decrease peripheral insulin resistance.
C) improve cardiovascular endurance, which is important for diabetics.
D) set a successful pattern, which will help in making other needed changes.
