Oprah Winfrey got emotional in her very first commercial for Weight Watchers.
In the commercial, the media mogul said: "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."
In the ad, the star struggles while working out.
See Oprah through the years:
She said: "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?'"
Oprah owns a 10 percent stake in the company, which she purchased in October.
She also had inspiring words for people struggling: "I feel that way, and I know millions of other people feel that way. Are you ready? Let's do this together."
