Oprah Winfrey, 61, has found a silver lining from her long-term weight struggle. The Queen of Talk is on a crash diet again, but this time it has to do with her newest business venture.

On Monday, Oprah signed a five-year deal with Weight Watchers International Inc. amid the company's struggle to keep its figures up in the face of cheaper digital rivals, noted Bloomberg.

By signing the deal, the owner of The Oprah Winfrey Network (OWN) has agreed to pay $43.2 for 10 percent of Weight Watchers' stake.

Unsurprisingly, because of Winfrey's influence in the country, the deal quickly gave the weight loss company a boost. Its shares increased to $13.92 following the announcement that Oprah has signed the deal.

In an instant, Winfrey just re-earned what she spent for the deal. Work It SOVA has learned that Oprah earned $45 million on paper after the partnership was announced to the market.

Speaking of her investment in a statement, Winfrey said, "Weight Watchers has given me the tools to begin to make the lasting shift that I and so many of us who are struggling with weight have longed for."

She then went on to say, "I believe in the program so much I decided to invest in the company and partner in its evolution."

On the other hand, Weight Watchers President and CEO Jim Chambers said, "We are expanding our purpose from focusing on weight loss alone to more broadly helping people lead a healthier, happier life."

The boost in Weight Watchers' figures does not come as a surprise since the country has provided good reception to everything Winfrey recommends.

In fact, the "Oprah's Favorite Things" segment in her show was a blessing to many companies and manufacturers of the products she recommended during the segment, as per Reuters.

Companies who basked under good profit all thanks to Oprah's star power include shape-fitting Spanx and plastic knives maker Kyocera.
