     Americans have never before exercised and dieted as eagerly as they are doing today. As a result,

they do not only look younger and slimmer, but feel better. Because of increased physical fitness, life

expectance in the nation has risen to seventy-three years, with fewer people suffering from heart disease,

the nation's number one killer.

     Jogging ( 慢跑 ), the easiest and cheapest way of improving the body, keeps over 30million people

Dieting, too, has become a national  pastime. Promoters of diets that eliminate eating one thing or another, such as fats or carbohydrates ( 碳水化合物 ), promise as much as 20- pound weight losses within two

weeks. Books describing such amazing diets always head up ( 居……之首 )the best-seller lists because people who are overweight want to lose weight quickly and easily.

     Nevertheless, jogging and dieting, carried to extremes, can be harmful. Many confused joggers

overdo and finally suffer from ankle and foot damage. Dieting, fortunately, becomes only a temporary

means for shedding a few  pounds while the body lose the balanced nutrition ( 营养 )it requires, so most

dieters cannot keep on diets. Above all, common sense should be the keystone for any dieting and

exercise plan.
