Brief Summary

The goal of this clinical trial was to see if learning and practicing mindful eating in a group was helpful for people who had bariatric surgery. The main questions it aims to answer are:

• complete questionnaires before the group started and after it ended, about their eating habits, mood, anxiety and other similar issues
• complete a questionnaire right after each session asking them what they found helpful and hindering about that session
