In the United States,30 percent of the adult(成年人) population has a "weight problem". To many people, the cause is clear, we eat too much. But scientific evidence (证据)does little to support this idea. Going back to the America of 1910, 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 TV.

Several modern studies, moreover, have shown that fatter people do not eat more on average(平均地) than thinner people. In fact, some investigations (调查)such as a 1979 study of 3 545 London office workers, reports that 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 fat they lost. The more they ran, the more they ate. Thus, those who ran the most ate the most, yet lost the greatest amount of body fat.
