Constructing practices open to listening and to the participation of clients is one of the greatest challenges faced by health professionals, who have been trained through models that prioritize technical expertise, and who are constrained by health systems that privilege profitability over human encounter. An area of special interest is the nutritional practice that is exercised over fat bodies because of its ability to (re)produce stigmatizing discourses and participate in interactions that may affect the physical and mental health, and social justice of clients. Based on relational constructionism, this research seeks to promote conversations between different voices involved in nutritional practice: fat women and men, nutrition students and nutritionists; to co-construct resources for a relational nutritional practice that open possibilities to alternatives which are sensitive to the dreams expressed by those who are immersed in its daily exercise. Through a relational action-research method, encounters were formulated to promote progressive exposure to increasingly dissimilar perspectives, and thus come into greater contact with difference, enabling the opening of more complex possibilities. This commitment to multiplicity resulted in the co-creation of resources for a relational nutritional practice with/to fat bodies, which include: honoring relational history, opening to multiplicity, exercising critical reflexivity, rekindling curiosity, applying relational responsibility to coordinate difference, being sensitive to what we invite to co-create in our interactions, recognizing that weight is not "neutral", opening the practice to multiple conceptualizations of health, aiming to situated practices and doing activism to question the system. It should be noted that, given the interest to open more and more possibilities, the resources presented, more than an ultimate goal, constitute an input to continue opening conversations.
