Introduction: Moderate weight loss (5–10%) translates into health benefits, including improvement in cardiovascular risk. It is essential to assess the results and indicators of success in treating obesity, which is the objective of this work.

Methods: A retrospective study of patients with overweight and obesity, followed in Nutrition consultation between 2004 and 2010. We analyzed biodemographic and anthropometric variables, consultation reason and weight history and treatments. We used the t-test for independent samples, χ² tests to statistical differences and repeated measures model assessed the weight gain. We estimated a multiple linear regression model to identify risk factors in weight loss. The significance level was 5%.

Results: Of 1947 patients with diagnostic of overweight or obesity, we analyzed 389, mean age 52 years (±15.3), 53% female. Overweight was the main reason for the consultation (63.8%). To all were prescribed a personalized meal plan, encourage physical activity and prescribed drugs to 10.8%. The mean follow-up was 12 months. The greatest weight loss, it was up to 12 months (P<0.005). At 3, 6 and 12 months, 66.8, 68.4 and 71.9%, respectively, lost weight. At 12 months, 39.5% lost more than 5% of their initial weight. The women lost more weight at 6 and 12 months (P=0.045). The reason for the consultation and number of visits has proven to be indicators of success in weight loss.

Conclusions: Most of the patients lost weight at all assessments and the bigger lost was at 12 months. Motivation and follow-up are indicative of greater success in weight loss.
