In the January’s O magazine, Oprah Winfrey confesses that she now weighs 200 pounds and has “fallen off the wagon,” usmagazine.com reports.

“I’m mad at myself,” writes Winfrey. “I’m embarrassed. I can’t believe that after all these years, all the things I know how to do, I’m still talking about my weight. I look at my thinner self and think, ‘How did I let this happen again?’”

In the article, Winfrey says she has struggled with an out-of-balance thyroid and the condition made her develop “a fear of working out.”

She confessed that she’s packed on 40 pounds since she weighed 160 pounds in 2006.

“Yes, you’re adding correctly; that means the dreaded 2-0-0,” Winfrey says. “I was so frustrated I started eating whatever I wanted — and that’s never good.”
