Ok, this thread is going in a weird direction, but when someone tells me I'm wrong I want to prove myself.
Ever hear of Dr. Vilhjalmur Stefansson? In 1906 he lived with the eskimos for a while. He said he never saw a fat Eskimo. Here is what he said:
"Eskimos, when still on their home meats, are never corpulent—at least, I have seen none who were. Eskimos in their native garments do give the impression of fat, round faces on fat, round bodies, but the roundness of face is a racial peculiarity and the rest of the effect is produced by loose and puffy garments. See them stripped, and one does not find the abdominal protuberances and folds which are so in evidence on Coney Island beaches and so persuasive against nudism.
There is, however, among Eskimos no racial immunity to corpulence. That is proved by the rapidity with which and the extent to which they fatten on European diets."
The Europeans brought obesity to the Eskimo. This is from Harper's Monthly Magazine, December 1935.
