A question that was was raised in the "Fat" discussion that no one answered: why is obesity a big problem in the US, to a far bigger extent than any where else in the world? Why is it not such a big problem in Europe, even in cheese and bread-eating/wine drinking France? Is it because Europeans are more obsessed about appearance and hence don't get overweight due to social pressure? Or, far more likely in my opinion, is the obesity proiblem connected to the US's nature as the center of the empire, the far more extensive influence of the overwork/fast food/sentient lifestyle culture in America?
And if being overweight is "natural" for many people, why do those who live in hunter-gatherer societies, the most "natural" human lifestyle, rarely show excess weight? No, they are not underfed, people such as Marshal Sahlins have demonstrated in numerous studies that in fact they are well-fed, in good health, without the degenerative diseases of the industrial world, and work a lot less than us, and have societies that are much more egalitarian and in fact often non patriarchal.
