Sarah Palin has been spotted out and about looking much thinner recently. We know she reps Alaska. Is she on the Cold Diet? Probably not, but fuck, that would be awesome if she was.

Anyway, she's gone ahead and cleared things up— she's not suffering from any ailment that is causing her to get thin or anything. In fact, she's working on a fitness book.

"Our family is writing a book on fitness and self-discipline focusing on where we get our energy and balance as we still eat our beloved homemade comfort foods," she says. "We promise you what we do works and allows a fulfilling quality of life and sustenance anyone can enjoy."

Watch out, Lena Dunham.
