Passage Four Questions 26 to 30 are based on the following passage.<o:p></o:p>
Exercise is one of the few factors with a positive role in long-term maintenance of body weight. Unfortunately, that message has not gotten through to the average American, who would rather try switching to “light” beer and low-calorie bread than increase physical exertion. The Centers for Disease Control, for example, found that fewer than one-fourth of overweight adults who were trying to shed pounds said they were combining exercise with their diet.
In rejecting exercise, some people may be discouraged too much by calorie-expenditure charts, for example, one would have to briskly walk three miles just to work off the 275 calories in one delicious Danish pastry. Even exercise professionals concede half a point here. “Exercise by itself is a very tough way to lose weight.” says York Onmen, program director of the President’s Council on Physical Fitness and Sports.
Still exercise’s supporting role in weight reduction is vital. A study at the <st1:place w:st="on"><st1:PlaceName w:st="on">Boston</st1:PlaceName> <st1:PlaceType w:st="on">University</st1:PlaceType> <st1:PlaceName w:st="on">Medical</st1:PlaceName> <st1:PlaceType w:st="on">Center</st1:PlaceType></st1:place> of overweight police officers and other public employees confirmed that those who dieted without exercise regained almost all their old weight, while those who worked exercise into their daily routine maintained their new weight. If you have been sedentary and decide to start walking one mile a day, the added exercise could burn an extra 100 calories daily. In a year’s time, assuming no increase in food intake, you could lose ten pounds. By increasing the distance of your walks gradually and making other dietary adjustments, you may lose even more weight.
