New photos of Sarah Palin looking very thin have caused a stir online, and now the former Alaska governor and 2008 VP nominee tells PEOPLE she's just fine and is, in fact, working with her family on a new fitness book.
In an email to PEOPLE on Tuesday, Palin – who's known to treat houseguests to a smorgasbord of homemade treats such as moose chili, chocolate cream pies, pecan pies and lemon meringue pies – wrote, "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, 48, says she will discuss the topics in "our unique and motivating book."
"We promise you what we do works and allows a fulfilling quality of life and sustenance anyone can enjoy," she adds.
It is unclear if Palin has a contract for the upcoming book or when the work will be published.
