Oprah Winfrey debuts Weight Watchers commercial

Oprah Winfrey made a big commitment to Weight Watchers in October, and it wasn't just to shed a few pounds. The media mogul bought 10 percent of the company for $43.2 million and agreed to be the face of Weight Watchers for five years.

Winfrey, who is working with a Weight Watchers coach and its mobile app, has finally released her first commercial with the company.

The commercial is stylistically similar to Winfrey's past promotions for her TV specials, with a self-help tone and an uplifting soundtrack.

She says, "Inside every overweight woman is a woman she knows she can be. Many times you look in the mirror and you don't even recognize your own self because you got lost, buried in the weight that you carry."

Winfrey continues, "Nothing you've ever been through is wasted, so every time I tried and failed, every time I tried again, and every time I tried again, has brought me to this most powerful moment to say, 'If not now, when?' I feel that way, and I know million son other people feel that way. Are you ready? Let's do this together."

The commercial has aired in the U.K., and her U.S. campaign is expected to roll out soon.

The TV personality, who has famously struggled with her weight for years, said in a statement in October: "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. I believe in the program so much I decided to invest in the company and partner in its evolution."

Winfrey's best friend, "CBS This Morning" co-anchor Gayle King, also participates in Weight Watchers.
