The implication is that the current food pyramid disproportionately weights against proteins and fats. Assuming that Americans follow the current pyramid (this is a hell of an assumption), then any change to the pyramid that asks them to change their diets in favor of more protein and fat is likely to result in them eating more meat.
In reality, I don't think anybody in the US follows the food pyramid religiously. But I do think people (try to) follow the main strokes of what the government tells them is a healthy dietary balance, and so any recommendation to increase their fat/protein intake will result in more meat consumption even if the guidelines doesn't itself proscribe that as the only source.
