Promoting Positive Mental Health for Sustainable Eating Behaviors

Participants will engage in 6 weekly group session of two hours. One part will be held by a trained dietician and will focus on nutritional education, particularly emphasizing the adoption of healthy and sustainable eating behaviors. The remaining part will be dedicated to a group psychological intervention inspired by the principles of Well-Being Therapy and will be held by a trained psychologist. During these sessions, participants will be introduced to the six dimensions of psychological well-being and will be gradually provided with cognitive-behavioral strategies to enhance psychological well-being and seek a balance between the presented dimensions. Participants will be given cognitive-behavioral tools to recognize justification cognitive mechanisms and replace them with more functional cognitions. These objectives will also be achieved through the use of a food diary to highlight emotions and thoughts experienced during food intake.

Participants will receive treatment as usual (TAU) by participating in 6 weekly group sessions of two hours of a Basic Nutritional Intervention (BNI) held by a trained dietician. This course focuses on promoting healthier lifestyles through nutritional education, diet monitoring using a dedicated food diary, and recommendations for proper physical activity.
