阅读理解题)阅读理解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 Center 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 caloric-expenditure charts; for example, one would have to briskly walk three miles just to work off the 275 calories in one delicious Danish pastry (小香饼) . Even exercise professionals concede half a point here. “Exercise by itself a very tough way to lose weight,” says York Onnen, program director of the President’s Council on Physical Fitness and Sports.
