US media have been speculating for some time over former Alaskan governor and 2008 US vice president nominee Sarah Palin’s radical weight-loss in recent months.
But the 48-year-old may have revealed the reason behind her radical drop – she is writing a fitness book.

Famed for her Alaskan hospitality, Sarah is known for giving visitors to her home a banquet of homemade treats, including moose chili, chocolate cream, pecan and lemon meringue pies, but these days guests might be a little disappointed.
“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 told People magazine.

It is unclear if Palin has a contract with a book publisher for the project or when the work will be published.
However, her daughter Bristol (21) is hitting the headlines for another reason. Bristol is currently competing on Dancing With the Stars, but had an on-screen meltdown, accusing her dance partner Mark Ballas of not being committed to the competition and wanting to dance with a better dancer.
