Abstract OBJECTIVE: Assess the lifestyle habits, including food patterns, of patients who underwent Roux-en-Y gastric bypass (RYGB) and to identify predictive factors in weight loss and regain. METHODS: Obese patients (100) who underwent RYGB from 1998 to 2008 were included. Dietary habits were assessed by using 24 h dietary recall and the Food Frequency Questionnaire. Rates of weight regain and the percentage of excess weight loss (EWL) were calculated. Patients were also asked whether they attended nutritional follow-up visits after the operation and about the type and regularity of physical activities. RESULTS: The mean age was 45.1 ± 9.9 y, and the majority of the patients were women (84\%). Mean EWL was 59.1 ± 20.3\%. Weight regain was seen in 56\% of the patients with 29\% of the patients having regained over 10.1\% of the minimum weight reached after RYGB. Weight regain increased significantly with time after surgery (up to 2 y: 14.7\%; from 2 to 5 y: 69.7\%; over 5 y: 84.8\%). Poor diet quality characterized by excessive intake of calories, snacks, sweets, and fatty foods was statistically higher among those who regained weight. Sedentary lifestyle and lack of nutritional counseling follow-up were also significantly associated with regaining weight. CONCLUSION: Despite satisfactory results of EWL, the patients did not properly maintain the lost weight, mainly after 5 y postsurgery. Major factors that influenced this weight gain were poor diet quality, sedentary lifestyle, and lack of nutritional counseling follow-up. Copyright © 2012 Elsevier Inc. All rights reserved.
