浙大宁波理工第二期阅读 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 exercise. 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 food. In rejecting exercise, some people may be unduly discouraged by calorie-consuming charts; for example, one would have to quickly walk three miles just to work off the 275 calories in one delicious cake. Even those who support exercise agree half a point here, and say Exercise by itself is a very tough way to lose weight. Still exercises supporting role in weight reduction is essential. A study at the Boston University Medical Center of some overweight adults showed 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 accustomed to sitting long and decide to start walking one mile a day, the added exercise could burn an extra 100 calories daily. In a years time, supposing no increase in food in-take, you could lose ten pounds. By increasing the distance of your walks gradually and making other food adjustments, you may lose even more weight. -------------------------------------------------------------------------------- 1.
