A personalized agent-based chatbot for nutritional coaching

Intelligent systems increasingly support users' behavior change, including exercise adherence, smoking cessation, and healthy diet adoption. Their effectiveness is affected by the personalization degree of advice/coaching and HMI mechanisms.

The system provides diet recommendations and tracks the user's food intake and nutritional behaviors to promote a healthy lifestyle. The study concludes with a user study and performance evaluation.
