Reuters reported in April 2025 that WeightWatchers' stock, which traded as high as $100 in 2018, lost most of its value last year as the company faced revenue declines, liquidity concerns, and celebrity shareholder Oprah Winfrey's decision to exit its board.

The well-known and popular diet company, which assigns point values to foods, was founded more than 60 years ago.

WeightWatchers filed for Chapter 11 bankruptcy protection Tuesday, saying it plans to slash debt and stay in business. Why it matters: The company has been grappling with sinking sales amid the surge of weight-loss drugs and changing health habits.
