Passage Four Exercise, everyone advises! But immediately, when you try, you run into trouble. There is so much contradictory, sometimes incorrect advice about exercising that you become confused. Test yourself on the following true false quiz. It will tell you what you need to know. 1. To lose weight you should always "work up a good sweat" when exercising. False. Sweating only lowers body temperature to prevent overheating; it does not help you reduce weight. You may weigh less immediately after a workout, but this is due to water loss. Once you replace the liquid, you replace the weight. 2. You burn more calories jogging one mile than walking the same distance. False. You use the same amount of energy whether you walk or jog the mile, since in both cases you are moving the same weight the same distance. The speed doesn’t matter. Of course, if you jog rather than walk for 30 minutes, you’ll cover more distance, and therefore burn more calories

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 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 (小甜饼). Even exercise professionals concede half a point here. "Exercise by itself is a very tough way to lose weight," says York Onnen, program director of the President’s Council on Physical Fitness and Sports.
