Eat more, Play more—Weight Less

In the United States, 20 to 40 percent of the adult population have a “weight problem”. To many people, the cause seems obvious: we eat too much. But scientific evidence does little to support this idea.

Several modern studies have shown that fatter people do not eat more on average than thinner people and that slim people are more active than fat people.

I believe that this shows overweight people can become relatively slim gradually via a progressive program of regular exercise. The key is regular, enjoyable activity.

Use of energy(calories) by the body falls into two categories. The first is energy used for essential bodily functions—digestion, heart beat, breathing—and BMR(新陈代谢). In an average-sized adult, BMR requires about 1400 calories per day.

The second category is energy used for physical activity—standing, walking and all other movements. Together with the BMR, it makes up total calorie use, which should be balanced by food intake for weight to remain stable.

For years now, we have known that dieting—especially severe dieting(400 calories per day, for instance)—decreases BMR. This is the body's defense system to keep energy when food supply is reduced. Unfortunately, it tends to weaken the diet's effects by enabling the body to “get by” on fewer calories. For this reason, I believe that severe dieting is not a good way to lose weight, and all dieting should be seen as a temporary measure.

In addition to helping weight loss and continued weight control, regular exercise has many other features to recommend it. While weight loss by dieting alone results in some loss of muscle as well as fat, weight loss by exercise and moderate dieting leads to an increased proportion（均衡）of muscle mass. The regular exerciser has good heart function too.

Regular exercise helps to raise blood levels of high－density lipoprotein(HDL) and increased exercise leads to increased food intake and thus to increased intake of critical nutrients (营养).

The benefits of eating more because of an increase in physical activity are not widely appreciated. Many people in this country, by actual measurement, have remarkably low calorie intake. Often the amount is so low (1 200 to 1 800 calories a day) that nutritionists worry about the adequacy(足够的)of their vitamin and mineral intake. And too little food, with inadequate fiber content, leads in the old population to chronic constipation(长期便秘)．

To sum up, most Americans still get too little regular exercise, and it is within this group that almost all obesity is found. Severe dieting should not be used as it is unpleasant and tends to be self-defeating. Moderate dieting combined with regular exercise is much more effective and enjoyable. The choice is yours: life on the sofa, nibbling celery or the active, healthy-eating, healthful way.

【解析】

试题分析：本文叙述了美国人越来越多的人有肥胖病，有很少的证据表明因为他们是吃的太多，文中给出了引起肥胖的原因，吃得足够多的好处以及一些减肥的方法，最后文章给出结论：没有进行适当的锻炼是导致肥胖的原因，建议不要再使用节食的方法来减肥。

1.根据we eat too much. 因为dueto+doing，故用eating.

2.根据But scientific evidence does little to support this idea.因为evidence是不可数名词，所以谓语动词用单数，故用supports.

3.根据Several modern studies have shown that fatter people do not eat more on average than thinner people and that slim people are more active than fat people.这里应该活动的少，故用less.

4.根据The benefits of eating more because of an increase in physical activity are not widely appreciated.可知这段主要谈论的是益处，故用benefits/advantages.

5.根据The second category is energy used for physical activity—standing, walking and all other movements. Together with the BMR, it makes up total calorie use, which should be balanced by food intake for weight to remain stable.身体的活动，故用physical.

6.根据Often the amount is so low (1 200 to 1 800 calories a day) that nutritionists worry about the adequacy(足够的)of their vitamin and mineral intake.And too little food, with inadequate fiber content, leads in the old population to chronic constipation(长期便秘)．吃足够的食物能够摄入足够的维生素和矿物质以防得便秘。故用adequate/enough.

7.根据While weight loss by dieting alone results in some loss of muscle as well as fat, 因为这一部分都是用动词的ing形式来表达，故用resulting.

8.根据The regular exerciser has good heart function too.因为这里修饰动词故用副词regularly.

9.根据内容可知是对于上文的总结，故用summaries/conclusions.

10.根据Severe dieting should not be used as it is unpleasant and tends to be self-defeating.故用avoided/stopped.
