Hi everyone, right after I read the PB, I happened to read this article about the remarkable endurance of sled dogs:
Anyway, the interesting part was this paragraph:
"YOU WOULDN'T KNOW IT to look at Tony, because he's pretty slight, but he's fed a diet that's mostly fat—up to 60 percent. "You'd kill a pet dog with that," says Erica McKenzie, a professor of large-animal medicine at Oregon State University who's studied sled dogs with Davis. If people ate such a diet, we'd all be diabetics living—not for long—on Lipitor. "In sled dogs we have a model where they exist continuously on a high-fat diet and are highly insulin sensitive," says Davis. "It raises the question of whether all those associations [between fatty diets and diabetes] are just an association and not a cause and effect. Or is there something else that goes along with a high-fat diet in humans that causes insulin resistance? Or maybe there's something you can do while eating a high-fat diet that prevents you from developing insulin resistance."
