These Celebrities All Lost Weight With WW and Are Living Proof the Program Works

Oprah Winfrey is perhaps the most high-profile celebrity associated with WW. In 2015, she bought 10 percent of the company, and she remains an active ambassador of the brand. "I have had a better life since being a part of the WW family," Oprah said in a video on the company website.

But she doesn't just tout the benefits of the program; she's living proof that it works. As of 2018, Oprah lost 42 pounds through her experience with WW, and she has kept it off. Based on her plentiful vegetable garden, line of healthier frozen food, and overall positive outlook on life, Oprah embodies everything about the WW program.
