Introduction: In Brazil, excess weight has reached epidemic proportions, and other chronic non-communicable diseases (NCDs) emerge. In this scenario, the importance and need for effective weight loss treatments arises, however, the incidence of abandoning these treatments is quite significant. In this context, the importance of understanding these reasons emerges. Objectives: To identify the reasons that lead to the abandonment of nutritional treatment for weight loss, according to the perception of overweight individuals. Materials and Methods: The present study was a qualitative research, where interviews were conducted to investigate the reasons that may lead to treatment abandonment for weight loss. The sample consisted of 12 overweight individuals, who have already undergone weight loss treatment with a nutritionist and abandoned it. Results: It can be inferred that the difficulties to continue the treatment and factors related to the professional's attitude were indicated by the participants as being the triggers of abandonment. Discussion: The lack of results is explained by the anxiety of individuals to perceive weight loss. The daily routine and access to recommended foods become obstacles to the continuity of treatments. The prescribed diet plan that is often shown to be somewhat restrictive and in this context the empathy of the nutritionist is necessary to assist in coping with excess weight. Conclusion: In fact, satisfaction with the treatment, which includes its satisfactory evolution, the achievement of the necessary changes and the professional's empathy, are situations that positively interfere with its persistence.
