In the United States, 30 percent of the adult population has a "weight problem". To many people, the cause is obvious: we eat too much. But scientific evidence does little to support this idea. Going back to the America of 1910, we find that people were leaner 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 than thinner people. In fact, some investigations, such as a 1979 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 found the following interesting fact:
The more the man ran, the greater loss of body fat.
The more they ran, the greater their increase in food intake.
Thus, those who ran the most ate the most, yet lost the greatest amount of body fat.
