Okay if you're an Oprah Winfrey fan or even if you're not you know her for her popular Book Club. Well Oprah's taking a departure from discussing fiction/non-fiction novels on her self-titled talk show to "diet" books. My prediction: Oprah's officially boost up the sales of diet books nationwide.

"The Oprah book club has been quiet for months, but the Winfrey touch remains golden.
Just ask the publishers of diet doctors Michael F. Roizen and Mehmet C. Oz.
Since an appearance last Thursday on Winfrey's television talk show, books by Roizen and Oz have occupied the top three spots on the best seller list of Amazon.com, with customers buying both the book alone and the book and DVD of their new work, "YOU: On a Diet," and the hardcover edition of a previous text, "YOU: The Owner's Manual," a million seller in 2005 thanks in part to Winfrey.
"Oprah obviously has a passion for their work. It's very exciting," said Martha Levin, publisher of the Free Press, an imprint of Simon & Schuster that has increased the print run of "YOU: On a Diet," from 650,000 to 950,000."
