Oprah Winfrey certainly hasn’t given up on dieting yet — she just revealed that she’s lost “over 40 pounds” on Weight Watchers as part of the company’s latest advertising campaign, sending shares soaring.

The U.S. weight loss and diet control market totaled $65 billion in 2015, according to a report by Marketdata Enterprises Inc, a market research publisher that has tracked the diet market for 28 years. Flat to low growth is expected in the future.
