Weight Watchers is a popular weight loss program known for getting Celebrities to tout their products, and now, Weight Watchers’ stock rises when Oprah Winfrey, 61, makes a television ad for the company. The new ad features videos of Winfrey exercising and working out, and talks about how the talk show host has struggled over the years with her weight, and ends with the star asking if viewers want to join her, and her saying, “Let’s do this together.” Not only did Weight Watchers’ stock rise, Oprah helped the company by tweeting the commercial to more than 30 million followers Tuesday. Oprah also helped them out by buying some of the Weight Watchers’ stock.

The stock has gone up to a price of $23.05 a share as of Wednesday.

Oprah buys 10 percent stake in Weight Watchers’ stock and it rises

Since October when Oprah bought a 10 percent stake in Weight Watchers, its stock has tripled in value. The company has also made a few changes in its program to make their weight loss plan fit better with the talk show host’s message to live a healthy and happy life. She is said to have paid around $43 million, and now the stock is worth about $148 million. Weight Watchers has said to have been hurt in recent years by things like fitness trackers and food tracking apps. Bringing in Winfrey is helping things out, and Winfrey has already been on “The Ellen DeGeneres Show” to announce that she has lost 15 pounds so far. She is said to have been on the program since August.

New program receives mixed reviews

The new heathier and happier living strategy of Weight Watchers is receiving mixed reviews from dieters. Its being touted as holistic, rather than a pure diet plan. For instance, the new version involves more exercise, and has a Smart Points program to get dieters away from saturated fats and sugars. However, the same foods are still on its menu, but some items have had their point value changed. For instance, dulce de leche ice cream bars have double points now. Some users are not so happy about the new system or its new app, as they believe the Smart Points program is too restrictive.

Smart Points system uses special algorithm

The Smart Points system has an algorithm to determine a food’s calories, protein, saturated fat, and sugar as a way to determine point value. Protein wins out for lower points, sugar and fats get more. Points are also based on age, weight, height, and gender. So, as these changes occur, Weight Watchers’ stock rises as Oprah touts their new, healthier, and happier lifestyle.
