Problem

NEDA shut its human-staffed helpline and moved to an AI chatbot after the helpline staff voted to unionize. Users then said the bot gave advice that fed eating disorders.

Approach

Critics said Tessa recommended calorie counting and a deficit of up to 1,000 calories a day, and suggested skin calipers. NEDA said the Body Positive program may have given harmful information and took it down until further notice for an investigation.

NEDA took Tessa offline after users reported weight-loss advice. The association said it would investigate potentially harmful information.
