Jeff Garlin knows he's "really screwed up," but once he accepted the fact that he's a food addict, that Oprah lightbulb went off in his head.

"I haven't had sugar in over a year," he told Jon Stewart on 'The Daily Show With Jon Stewart' (weeknights, 11PM ET on COM). "I haven't had fast food in over a year ... if you have a cookie and go, 'here just have a piece,' that's like me taking my first drink,' so I don't do it."

Good for you, Jeff! Stay the course, because you look fabulous.
