A few weeks back, billionaire media mogul Oprah Winfrey purchased a 10 percent stake in Weight Watchers to become one of the members of the company's board and now the star has stated she'll also be the face of the company, as Weight Watchers' Oprah involvement grows even further.

Winfrey has famously struggled with weight fluctuations for decades, having had serious problems with maintaining her figure after losing a lot of pounds, which has prompted many to wonder how appropriate the Weight Watchers Oprah ads would be, considering she's not exactly the poster girl for maintenance.

According to CNN Money, the new phase of the Weight Watchers Oprah partnership was announced late last week, when the company's CEO, Jim Chambers, said that the beloved media personality and businesswoman would be joining the marketing efforts for the brand, giving further expansion to the so-called Oprah Effect.

After having been active on television and other media for well over three decades, Winfrey has led something called "The Oprah Effect," which is to say, anything she endorses in one way or another ends up becoming a success - and, as The Daily Mail reports, the Weight Watchers Oprah involvement has already brought her massive gains.

Just hours after the first Weight Watchers Oprah purchase was first announced (after the talk show host bought a 10 percent stake at $43.2 million), Oprah went on to make $70 million as her involvement in the company made it soar value-wise, with investors jumping at the chance to see the company soar once more now that it has the backing of the biggest public opinion influencer in America.

Oprah has also reportedly lost 15 pounds since last August, which is something that will make her involvement with the program particularly more interesting (even more so considering its revenues were tanking ahead of her involvement), but NPR doesn't seem too convinced the move will benefit dieters, as the new spokesperson is a famous "yo-yo dieter," while pointing out the heavy criticism Weigh Watchers' methods have received for years.

Could the Weight Watchers Oprah involvement save the company? Only time will tell.
