【雅思聽力】肥胖(4/4)

To lose weight, a person should avoid certain foods, but also eat more fruit, vegetables and cereal foods such as bread, pasta and rice. Rather than focusing on what people should not eat, the focus should be on the healthy food that people should eat. Losing weight doesn't mean being on a monotonous diet. In fact, it's recommended that everyone eats 30 different foods a day. A problem with many diets and weight loss programmes is that they tend to make extravagant promises of rapid weight loss with very little exercise or no exercise at all. It is in fact not healthy to lose more than a kilo per month, but some losing weight at that rate run the risk of losing muscle, whereas a realistic, healthy weight loss programme needs to include regular exercise. And for those who've repeatedly been unsuccessful in the attempt to reduce their weight, it's better to accept that they have a larger body than a fashion model, as well as to make some changes in their diet and to do regular exercise. They may not live longer, but at least they'll enjoy their time more.
