Being overweight is directly related to the high level of anxiety and the poor quality of life. The objective of the study was to verify the levels of anxiety and quality of life in overweight adults submitted to nutritional monitoring. Anxiety levels were assessed by applying the Inventory "The Mind Overcoming Mood" and Quality of Life using WHOQOL-bref instrument, as well as socioeconomic and demographic characteristics. For the comparison of the scores of each domain by gender the Student's T Test was used, and the four domains in the genres were used and in general the Tukey's test was used, both at 5% significance. The majority of the patients were females (84.85%, n=28) and had an average Body Mass Index of 32.57±4.75 kg/m², classified as obesity class 1, anxiety was 21.88±11.68 points, with the women presenting the highest mean. Among the interviewees, 57.6% (n=19) considered their quality of life to be "good". The best scores obtained by the WHOQOL-BREF were in the Social (73.48) and Physical (68.29) domains. There was a significant difference (p <0.05) in genders, only in the Psychological domain. In the evaluation of the domains, in the female gender and in the general evaluation, the Social domain had a higher mean score (p <0.05) than the Psychological and Environmental domains, and in the male gender there was no significant difference between the mean scores between the domains. It was concluded that the majority of the patients presented obesity class 1, and in the female gender there was a higher anxiety score and lower quality of life in the psychological domain. It is suggested that other studies are conducted to analyze the influence of anxiety on the treatment of excess weight, as well as the impact of reducing body weight on the quality of life of these patients.
