Carole is a teenage girl. She thinks she is a bit too fat, or rather too strong. But she doesn’ t know how she becomes that way. Nowadays, people become interested in losing weight because being overweight can bring about many diseases. Carole has made up her mind to follow others’ example and plans to lose weight as well. Sometimes she feels so unhappy without knowing why. At these times, she often goes out to restaurants, bars and supermarkets for food. The things she likes to eat include bread, biscuits, and chocolates. Although she feels very full in her stomach, she can’t stop eating because of the enjoyment she gets. She is a little worried about her behavior and thinks that she might have an unknown disease or an unhealthy mind. With these questions, Carole goes to see a doctor. The doctor doesn’t think she has a disease, but suggests that she need self-discipline. People often say "eat less and exercise more," but one needs discipline to follow this advice. Since Carole says she enjoys eating although she feels very full, the doctor thinks this might be because Carole wants to forget about finishing work or doing a complicated homework assignment. Her feeling of unhappiness could start from something deeper, such as problems with family members or friends. The doctor says that Carole needs to find something that can bring fun to her life. Perhaps she should give up the habit of eating too much, and do something else instead, such as talking to someone over the phone, playing a video game or drinking extra tea. These methods could help Carole change the habit of eating too much and become healthy again.
