Weight Watchers sales declined rapidly in the last quarter, despite media celebrity Oprah Winfrey’s investment and advertising campaign.

Weight Watchers reported a 21% drop in quarterly revenue down to $259.2 million, and active subscriber membership dipped 4.8% during the fourth quarter ending Jan. 2, Reuters reports.

Winfrey joined the weight-loss company in October 2015 after it had experienced a nearly three-year decline in sales. She made a $43.2 million investment for a 10% stake and was added to the company’s board; its stock more than doubled on the day her involvement was announced.
