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
