In the United States,30 percent of the adult population has a "weight problem"． To many people, the cause is obvious: they eat too much． But scientific evidence does little to support this idea． Going back to the America of the 1910s,we find that people were thinner than today,yet they ate more food． In those days people worked harder physically, walked more, used machines much less and didn´t watch television． Several modern studies, moreo-ver,have shown that fatter people do not eat more on the average than thinner people． In fact, some investigations, such as the study of 3,545 London office workers, report that, on balance, fat people eat less than slimmer people．
Studies show that slim people are more active than fat people． A study by a research group at Stanford University School of Medicine found the following interesting facts:
The more the men ran, the more body fat they lost．
The more they ran, the greater amount of food they ate．
Thus, those who ran the most ate the most, yet lost the greatest amount of body fat．
The physical problem that many adult Americans have is that__________．
A．they are too slim
B．they work too hard
C．they are too fat
D．they lose too much body fat
在美国，30％的成年人都有体重问题。对很多人来说，原因再清楚不过了：他们吃太多了。但是几乎没有任何科学依据证明这一点。回顾十八世纪初，那时的人比现在的人瘦，然而却吃得多。那时候，他们工作比现在辛苦，走路比现在多，使用机器比现在少，也不看电视。另外，有些现代科学研究证明胖人并不比瘦人吃得多。其实，一些研究调查(如对3545名伦敦办公室员工的研究)发现，总体来说，胖人比瘦一些的人吃得少些。
研究表明，瘦人比胖人活动得更多。斯坦福大学医学院的一个研究组做的一项研究发现如下有趣的事实：
一个人跑得越多，身体里的脂肪就燃烧得更多。
跑得越多，需要的食物就更多。
因此，跑得最多的人就吃得最多，当然流失的身体的脂肪也最多。
