"But I still find it interesting, that apparently this effect could explain an enormous amount of the obesity puzzle. If, hypothetically, humans wouldn't have changed the composition of their diet or calorie expenditure at all, but their bodies are tuned to maintain a fixed amount of nutritions, the small drop in nutrition content alone could apparently explain a worldwide increase in obesity." This effect is easily explained by the "food pyramid" theory of nutrition, which emphasizes carbs as the major food source. It seems very clear that this is wrong, and the healthiest diet includes substantially more fat and protein. The other increasingly missing ingredient for a leaner population is called "exercise".
