Oprah Winfrey I Fell 'Off the Wagon'
Winfrey's yo-yo battle with the bulge spans most of her career, from her triumphant marathon run in 1994 to earlier this year, when she announced she'd been diagnosed with a thyroid disorder that left her fatigued and feeling heavy. That condition—plus a busy 2008 that included fallout from a sexual misconduct scandal at her school for girls in South Africa and her pivotal involvement in Barack Obama's campaign—caused Winfrey, 54, to miss workouts and slide into poor eating habits. "I took myself off my own priority list," she writes in O.
Now her challenge is to get healthy again—this time, she hopes, for good. "I can't believe that after all these years, all the things I know how to do," she writes, "I'm still talking about my weight."
