She liked it so much, she bought the company.
Oprah Winfrey will acquire a 10 percent stake in Weight Watchers International for $43.2 million and take a seat on its executive board, the company announced today. She will also receive options to buy an additional 5 percent stake.
"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," said Winfrey, who has famously struggled with her own weight problems, in a statement.
"I believe in the program so much I decided to invest in the company and partner in its evolution."
It was great news for Weight Watchers, which has seen its share price tumble recently because of changes in dieting habits. The announcement that the hugely influential broadcast and lifestyle mogul was coming on board sent shares soaring.
Weight Watchers made clear Winfrey will be no passive investor and will lend her very high profile to publicizing the company as it shifts its focus.
The statement said "she has joined the program and will candidly share her experiences and perspective along the way."
"We are expanding our purpose from focusing on weight loss alone to more broadly helping people lead a healthier, happier life," said Jim Chambers, president and CEO, Weight Watchers International Inc.
"Through our conversations, it became clear that there is tremendous alignment between Oprah's intention and our mission. We believe that her remarkable ability to connect and inspire people to realize their full potential is uniquely complementary to our powerful community, extraordinary coaches and proven approach."
"Weight Watchers and Oprah Winfrey make a powerful combination," said Ray Debbane, chairman of the company's board. "Oprah is a force of nature in connecting with people on a very personal level to live inspired lives. This partnership will accelerate our transformation and will meaningfully expand our ability to impact many millions of people worldwide."
Forbes magazine says Oprah is worth $3 billion, making her the 211th wealthiest American.
