The Best Way to Reduce Your Weight

You hear this：“No wonder you are fat.All you ever do is eat.”You feel sad：“I skip my breakfast and supper.I run every morning and evening.What else can I do?”Basically you can do nothing.Your genes，not your life habits，determine your weight and your body constantly tries to maintain it.

Albert Stunkard of the University of Pennsylvania found from experiments that，“80 percent of the children of two obese parents become obese，as compared with no more than 14 percent of the offspring of two parents of normal weight.”

How can obese people become normal or even thin through dieting?Well，dieting can be effective，but the health costs are tremendous.Jules Hirsch，a research physician at Rockefeller University，did a study of eight fat people.They were given a liquid formula providing 600 calories a day1.After more than 10 weeks，the subjects lost 45kg on average.But after leaving the hospital，they all regained.The results were surprising：by metabolic measurement，fat people who lost large amounts of weight seemed like they were starving.They had psychiatric problems.They dreamed of food or breaking their diet2.They were anxious and depressed;some were suicidal.They hid food in their rooms.Researchers warn that it is possible that weight reduction doesn’t result in normal weight，but in an abnormal state resembling that of starved non-obese people.

Thin people，however，suffer from the opposite：They have to make a great effort to gain weight.Ethan Sims，of the University of Vermont，got prisoners to volunteer to gain weight.In four to six months，they ate as much as they could.They succeeded in increasing their weight by 20 to 25 percent.But months after the study ended，they were back to normal weight and stayed there.

This did not mean that people are completely without hope in controlling their weight.It means that those who tend to be fat will have to constantly battle their genetic inheritance if they want to significantly lower their weight.

The findings also provide evidence for something scientists thought was true-each person has a comfortable weight range3.The range might be as much as 9kg.Someone might weigh 60-69kg without too much effort.But going above or below the natural weight range is difficult.The body resists by feeling hungry or full and changing the metabolism to push the weight back to the range it seeks.

答案与题解：

1.　D 问题问的是：什么决定了你的体重?A说的是：你的工作方式。B说的是：你的吃饭习惯。C说的是：你的生活风格。D说的是：你的基因。正确答案是D。第一段中有这么一句话：Your genes，not your life habits，determine your weight and your body constantly tries to maintain it.你的基因而不是你的生活习惯决定了你的体重，因此你的身体总是试图保持它。

2.　D 问题问的是：Jules Hirsch在他的研究中做了什么?A说的是：他让八个胖子不吃晚饭。B说的是：他让八个胖子不吃早饭。C说的是：他让八个胖子早晚都跑步。D说的是：他给八个胖子一种每天提供600热卡的流食配方。D是正确的。第三段有这么一句话：They were given a liquid formula providing 600 calories a day.他们被给予一种流食配方，每天提供600热卡。

3.　C 问题问的是：八个胖子出院后怎么啦? A说的是：他们发疯了。B说的是：他们自杀了。C说的是：他们又回到了原来的体重。D说的是：他们试图自杀。C是正确的。第四段的最后一句话是这样的：But months after the study ended，they were back to normal weight and stayed there.研究结束几个月后，他们的体重又回到了原来的样子并保持不变。

4.　B 问题问的是：Ethan Sims让他的调查对象干什么? A说的是：跟他们的基因遗传物做斗争。B说的是：增加他们的重量。C说的是：呆在家里。D说的是：减少体重。第四段有一个句子是这么说的：Ethan Sims，of the University of Vermont，got prisoners to volunteer to gain weight.Vermont大学的Ethan Sims让犯人自愿增加体重。可见B是正确的答案。

5.　A 问题问的是：科学家认为什么是对的? A说的是：每个人的体重都有一个适当的幅度。B说的是：每个人的体重幅度是9公斤。C说的是：每个人都想控制自己的体重。D说的是：每个人都想吃得高兴。正确答案是A。最后一段的第一句话是这么说的：The findings also provide evidence for something scientists thought was true-each person has acomfortable weight range.结论还证实了科学家认为是正确的一点，即每个人的体重有一个适当的幅度。
