Finally, we've got the skinny on how Today show weatherman Al Roker lost nearly 100 pounds. Last March, he underwent gastric bypass surgery the same procedure that helped Carnie Wilson slim down. "I have a much better relationship with food [now]," he tells USA Today. "I'm not sneaking. I'm eating out in the open. I enjoy my meals." Roker's surgery was filmed, and the entire Nov. 12 edition of Dateline NBC will be devoted to the operation.
