Sweeney, who is currently hosting her ninth consecutive season of "The Biggest Loser," leads the hit reality series in transforming the lives of show contestants and television viewers worldwide.

"The Mommy Diet" focuses on ways to get and keep physically and mentally healthy, while offering ways to slim down in a positive, attainable way after having a child. Dr. Oz, Holly Robinson Pete and Jillian Michaels are amongst those who provided endorsements for her book.
