Sarah Palin to Write Fitness Book

With new Sarah Palin photos causing a stir online, the former political figure and current pro celebrity has offered an explanation for her noticably thinner frame:

She's working with her family on a new fitness book!

She tells People, "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!"

Sarah Palin promises a "unique and motivating book."

"We promise you what we do works and allows a fulfilling quality of life and sustenance anyone can enjoy," the 48-year-old former Alaska Governor adds.

It is unclear when the work will be published or if haters will be singled out for criticizing her recent weight loss. Also unclear? What she bought at KMart (above).
