W: Good morning. Dr. Smith. I’ m not sure whether you can help me or not, but I’ m getting desperate!
M: Oh, what’ s wrong? What is making you so desperate?
W: Well, everybody laughs at me because I’m so fat. I’ve always been overweight. I’m trying to eat less but I don’t seem to be able to lose any weight. I don’t know what I can do. Maybe you can give me some medication?
M: Well, it is not a good idea to eat less. You should eat more healthy food like fruits and vegetables, and avoid fast foods like the hamburgers and hot dogs.
W: But hamburgers and hot dogs are my favorite.
M: That’s the problem. They contain high calorie that causes fatness. In addition to avoiding these high calorie foods, you should do some exercises. Physical exercise does a lot of good to health and will be an effective way to reduce weight. Medicine is not always the best solution to your problem.
W: I know, but I don’ t have time to do exercise. You know, I’ m busy at my work from morning to night. Besides, I am not rich enough to go to the gym.
M: You needn’t spend much time on exercise and you don’t have to go to the gym. I suggest that you walk more regularly. You could get off the bus one stop early and walk the last bit. When you walk, try to walk a little more quickly. You could also use the stairs instead of the elevator.
W: That’ s really a good idea.
M: You will succeed, if you act in accordance with my suggestions.
