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.
