In a new promotional video for the weight loss company, Oprah revealed that she's lost 26 lbs. since starting her diet – even while indulging in some of her favorite, notoriously high-carb foods.
"This is the joy for me," she explains. "I love bread. I love bread. I now just manage it, so I don't deny myself bread, I have bread every day."
The 61-year-old continued, "That's the genius of this program. I've lost 26 pounds and I have eaten bread every single day."
Winfrey spent a cool $43.2 million for a 10 percent stake in the company back in October – about 6.4 million shares. As part as the agreement, the former talk show host and frequent dieter joined the company's board and now serves as a spokeswoman.

After Winfrey shared the clip on Twitter Tuesday afternoon, the company's stock skyrocketed over 20 percent, closing at $13.29 a share, according to USA Today.
Only thirty minutes before the social media message, Weight Watchers' stock was trading at $11.35 a share, USA Today reported. In all, the tweet earned the star roughly $12.5 million dollars an hour.
And that's the power of Oprah.
