Jody, age 17, is a freshman at City Community College, where she is majoring in business. After classes she works in a fast-food restaurant. During summer vacation she had lost 20 pounds while on a well-known liquid formula diet. However, she has regained 15 pounds since the school term began. She is 165 cm (65in)tall, medium in build, and currently weights 71kg(156Ib). Jody has been overweight since childhood. As a teenager she has tried numerous fad diets. She usually loses about 10 pounds but then regains the weight within a few months. She tends to binge on high-calorie foods when feeling nervous or lonely. On occasion, she has used laxatives after binging to avoid gaining weight. She has also been taking an over-the-counter appetite suppressant containing phenylpropanolamine daily during the past year. One evening a forum was held on campus concerning "Eating Disorders. After the meeting, Jody talked with the speaker and expressed frustration regarding her difficulty maintaining weight loss and a fear of becoming bulimic.
