Losing Weight

Student A: Do I ever need to lose weight! I couldn"t believe the scales when I got on them this morning. I weigh 10 kilos more than I did last year. I am not sure it is because I eat fast food at the university cafeteria all the time or if it is because I no longer belong to the swim dub. All my clothes are too tight.
Student B: I have gained a lot of weight myself since starting university. But, I think we are too young to diet. Exercise is the key. I am going to the gym three times a week. I started two weeks ago and have already lost a kilo.
Student A: I think you have to eat the right food and exercise. The Atkins diet really controls what you eat, but my parents lost a ton of weight on it. I"m thinking about going on it.
Student B: No, I disagree. You can eat whatever you want if you bum it off. Exercise bums calories. If you exercise more, you lose weight. It is that simple.
Student A: Yes, you lose weight, but eating junk food and fast food like I have been doing is also not good for the heart. Diet impacts the body in lots of ways. Sugar is also very bad. I have noticed it impacts my moods. The trouble is, it seems to take a lot of will power to diet. I just love chocolate. I could eat chocolate bars all day long, but the energy they give me seems to be short-rived. I wish I could diet. I started watching what I ate after I gained the first five kilos, but instead of losing that 5 kilos I gained another five. My self-discipline is awful. I got my mother to stop sending me care packages of cookies from home, but my friends at the university residence I live in still get them, and they share, so I am still eating way too many sweets.
Student B: Just exercise more. Almost all the people at the gym are slim and look fit.
Student A: Yes, but just because they are slim, does not mean they are fit. It is important what you put into your body. I read you should have at least 10 servings of fruit and vegetables a day to stay healthy. Also, it is important to eat a lot of fish. We need to start thinking about when we get older. My grandmother has osteoporosis, a really humped back, and her doctor said it was because she didn"t get enough calcium when she was young.
Student B: You worry too much. We are young. Maybe I will start to worry more after I"m in my thirties, fight now I"m going to eat what I enjoy and exercise. Exercise is the most important thing for the heart.
Student A: Maybe, but the fight food is also important for the heart and many other health issues.
Student B: I like sport drinks for energy. I also get energy bars that taste like chocolate. And, I take a multivitamin/mineral supplement every day. Having enough iron in your body is especially important for women like you. Supplements are not expensive, and they give you what you need. It"s a lot quicker and easier to take a supplement than to stand over the stove cooking a full meal.
Student A: I am not so sure about supplements being useful. Often, they just pass through your body. It is much better to get your nutrition from eating the right foods. I understand if you are an athlete, you need a little more fat, but just going to work out in the gym three times a week does not make you an athlete, Paul. I don"t think you really look that much overweight, but I think you should read up on healthy eating.
Student B: Yea, yea, you sound like my mother.
Student A: As I said, diets are very hard to stick to, but sometimes you just have to bite the bullet and set up a proper diet. I have an appointment next week with the college dietician—he will draw me up a daily diet and tell me what to have for breakfast, lunch and dinner seven days a week. I don"t think I have trouble following it for breakfast and lunch, but mid-afternoon I just can"t stop snacking. Also, I like to eat before I go to bed, which I know isn"t good for you ... Nonetheless, I am determined to lose these extra 10 kilos in six months.
