This study aims to compare the preliminary effectiveness and feasibility of the Mindfulness-Based Health Promotion and Attachment-Based Compassion Therapy programs as opposed to usual treatments (workshops) on the eating behavior of patients with progressive weight gain after bariatric surgery in Brazilian patients at a private clinic. It was hypothesized that both interventions are feasible and that the self-compassion program may be more effective than the mindfulness program. Methods: The study will be divided into two phases: a cross-analytical study of those who underwent bariatric surgery and a randomized controlled trial only with the ones who had weight regain. Interventions will be conducted for eight weeks synchronously with three assessment points (baseline, post intervention, and 6-month follow-up), both online. The primary outcome will be a change in eating behavior. Secondary outcomes will include improved quality of life, enhanced body image satisfaction and reduced distortion (Brazilian Silhouette Scales for adults), better weight management (maintenance or weight reduction), increased frequency of activity and monitoring with the surgery team. Qualitative data will also be collected by online identification of a sub-sample of participants. Results: Improvements are expected in eating behavior, weight, reverse progressive weight gain, classification of self-image, quality of life, and levels of mindfulness, self-compassion, and anxiety.

It should be emphasized that this is a scientific crew, who have undergone high levels of confinement during space travel to Mars, O (10² Earth days), are living in semi-solitude and partial confinement conditions for durations of O (10³ Earth days), and even at the nominal termination of the mission, foresee a high-risk and arduous travel time of O (10² Earth days) back to the Earth.

Minimal and conservative design of spaces, lack of constant access to the exterior, and social solitude are among major factors contributing to the psychological well-being of the crew. Furthermore, the overall lower levels of natural light, accompanied by the minimum possible area of transparent facades, protecting the crew from harmful radiations and cold exterior, burden the mental conditions of the crew even more.
