In May 2023, the National Eating Disorders Association (NEDA) announced it would shut down its human-staffed helpline and replace it with an AI chatbot called 'Tessa.' Within days, a user reported Tessa was actively recommending calorie restriction and weight loss tips — the exact kind of advice that can trigger or worsen eating disorders. NEDA suspended Tessa immediately. Critics noted the timing was suspicious: the helpline staff had just voted to unionize days before being let go.
