Thin Sarah Palin is Actually Writing a Fitness Book With Family Secrets [PHOTOS]

Sarah Palin looks a bit too thin these days but the former Alaska governor explained to People magazine that she has been working on a book on fitness.  Some say she looks unhealthy with the drastic weight loss compared to her more voluptuous figure in the past.

She told 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!"

Palin has always been active in outdoor spots and activities since she was in her teens.  She even named her son "Track" because she loved running so much, she said to Wall Street Journal back in 2008.  Apparently, she was nicknamed "Sarah Barracuda" in her high school days when she was a track star.

The book's completion date and publisher has not been announced yet.
