Oprah Winfrey announced she was leaving WeightWatchers on Thursday and giving away all her stock - a move that follows the TV talk queen revealing that her recent dramatic weight loss was due to taking new weight-loss drugs.

A statement from Winfrey issued by the company said that the talkshow host, a public face for WeightWatchers since 2015, would donate all her shares in the company to the National Museum of African American History and Culture to eliminate any perceived conflict of interest around her taking weight-loss medications".
