Question

For most of us, dieting is an annoying fact life, With so much information available, it can be difficult to tell which weight-loss strategies really work．Let’s start by taking a look at some confusing myths(荒謬)。 　　1．All calories are created equal 　　What you eat, not how much, is the main factor behind weight gain, In fact, the body burns many more calories digesting carbohydrates than it does digesting fat, For every 100 calories of carbohydrates we consume in excess(超過)of our daily requirement, only 75 are turned into body fat．But 97 of every 100 excess fat calories fat calories are turned into body fat． 　　2．Desserts and fast foods are forbidden． 　　Some experts advise against describing foods as “ good ”and “bad ”Even cakes, pies, and ice cream can be worked into a diet, Moderation is the key．Besides, a plain hamburger on a bun is still a healthful choice, So is baked chicken or a green salad with low–cal, dressing, But watch out for French fries, and fried chicken of fish． 　　3．It makes no difference whether you’re top or bottom–heavy 　　In fact, where weight is distributed makes all the difference, Recent studies suggest that people who store fat on the upper body(apple shape)rather than on hips and thighs(大腿)腳(pear shape) may have an increased rick of heart disease, There is probably little you can do to change how your body is genetically programmed to store fat, But you can lost excess weight overall． 　　4．Fasting is the fastest diet． 　　Some studies suggest that suddenly reducing calorie intake puts the body into “starvation mode ”,which causes it to conserve calories and decreases the rate of digestion．The more often you deprive yourself of food, the better your body may get at storing calories, So, in the long run, repeated fasting may actually weaken your weight–loss efforts． 　　5．To keep weight off, simply watch what you eat 　　According to studies, exercise combined with dieting ensures weight loss better than dieting alone does．Experts also agree that having regular, moderate exercise is more important than occasional exercises, Researchers encourage patients to take the stairs instead of the elevator and park the car far from where you are going and walking． 　　6．It’s all your fault that you’re fat 　　Research at the University of Pennsylvania, School of Medicine indicates that body shape and size are in large part decided by a person’s genes, In short, some people are naturally more likely to be fat than other．Moreover, someone who was fat in childhood will have more fat cells than a person of average weight．Once made, the cells may enlarge or shrink(縮小)，but they never disappear． 　　Yet genes don’t have to control your shape, The size of your fat cells depends on you－on your eating habits and lifestyle, Most important, before getting caught up in dietary myths, let good sense shape your eating habits, Your body will thank you for it． (1) Which of the following statements is true?
