TV's well-known weatherman from the Today Show, Al Roker, is releasing a new diet book: Never Goin Back: Winning The Weight Loss Battle for Good. Mr. Roker tipped the scales at 340 lbs. (on a 5'8" frame) and had bariatric surgery in 2002. He did lose 100 lbs. but gained a lot of it back as he reverted to bad eating habits. He claims to have ended that cycle by changing his mindset and lifestyle, and is now 205 lbs. The book details his journey and his current tips for staying on path. You can listen to an excerpt from the book at: Parade.com/roker.
