Keys used the same disparaging arguments to dismiss observations of Inuit in the Arctic. Like Mann, Vilhjalmur Stefansson had also seen for himself how good health and a high-fat diet could go hand in hand; the Inuit diet, as we’ve seen, was at least 50 percent fat. And in 1929 Stefansson conducted that yearlong experiment of eating only meat and fat. Optimistically, he expected that these efforts would lead to “a path of garlands for the high-fat regimens” laid down by admiring colleagues. He was thus unprepared for his fall from grace. “And what a fall!” he wrote. “The first cloud in the sky was no bigger than a man’s hand, in fact no larger than a brief and friendly personal note from Dr. Ancel Keyes [sic]” in 1954.
