Money | WeightWatchers Oprah's New Bod Is a Gift to Weight Watchers Shares spike as she reveals 40-pound weight loss By Arden Dier Posted Dec 23, 2016 11:11 AM CST Copied Oprah Winfrey in Los Angeles on Oct. 17, 2016. (Photo by John Salangsang/Invision/AP, File) Oprah Winfrey has lost 40 pounds since joining Weight Watchers—and that's doubly good news for her. After climbing as much as 19% to $12.50 on Thursday, per Bloomberg, shares of Weight Watchers were sitting at $12.02 as of this writing, meaning the nearly 6.4 million shares in the company that Oprah bought for $43.2 million in October 2015 are now worth about $77 million. That's a $10 million boost from Wednesday, reports CNNMoney. Shares could continue to climb as Weight Watchers gears up for its busiest time of the year for adding new subscribers. Its membership has been growing for the past three quarters and the company hopes to stay the path with new TV ads featuring Oprah's slimmer bod. In one, the former talk show host claims she's still "eating everything I love—tacos, pasta. I've never felt deprived," per People. (See Oprah's "favorite things" here.)
