Introduction: Sleeve gastrectomy (SG) is an established bariatric procedure. However, long-term data on eating and lifestyle behaviors and their effect on weight outcomes are scarce. Therefore, this study aimed to examine these long-term behaviors and their associations to weight outcomes following SG. Methods: A long-term follow-up study (>5 years post-surgery) of 266 adult patients admitted to a primary SG surgery during 2008–2012 and who participated in a pre-surgery study was conducted. Data on pre-surgery demographics, anthropometrics, and medical status were obtained from the patients’ medical records. Data on long-term health status, anthropometrics, lifestyle and eating habits, eating pathologies, follow-up regime, and satisfaction from the surgery were collected by an interview phone calls according to a structured questionnaire. Results: Data of 169 patients were available before and 7.8±1.0 years post-SG. Their baseline mean age was 41.8±11.3 years, and 71.6% of them were females. The mean post-surgery excess weight loss (EWL) was 53.2±31.2%, and 54.2% had EWL of ≥50%. Eating 3–6 meals per day, not having the urge to eat after dinner, separating liquids from solids, avoiding carbonated beverages, and performing physical activity were related to better weight-loss outcomes (P≤0.026). However, frequent need for eating sweets, binge eating, and feeling guilty or sad after eating were related to worse weight-loss outcomes (P≤0.010). Furthermore, only a minority reported taking a multivitamin and participating in follow-up meetings after more than 1 year since the surgery (≤21.3%). Conclusions: In the long term following SG, approximately half achieved EWL of ≥50%, and physical activity, certain eating patterns, and eating pathologies were related to weight outcomes.
