Weight bias is present in different scenarios, one of them is the area of health on the part of its professionals. For this reason, the aim of this descriptive, observational and cross-sectional study was to determine whether weight bias towards people with obesity was observed among students of the Nutrition and Dietetics career of the Catholic University of Temuco and to provide corrective measures to prevent the bias. The participants of this study were 94 nutrition and dietetics undergraduate students from different years of study. Students answered the GAMS 27-Obesity. According to the results obtained in this study, future nutritionists have a predisposition to weight bias towards people with obesity, this can have a negative impact on the care of these patients. Implementing corrective measures, during professional training, can prevent weight bias towards people with obesity by future professionals, thus improving their quality of care and positively impacting the health of these people.
