title: Energy Intake and Food Habits between Weight Maintainers and Regainers, Five Years after Roux-en-Y Gastric Bypass.
abstract: We explored differences in dietary behaviours, energy, and macronutrient intake among individuals who had regained or maintained weight loss 5 or more years after Roux-en-Y gastric bypass (RYGB). This study assessed 27 adults who underwent RYGB an average of 12.1 ± 3.7 years before this study was conducted. Dietary assessment was performed using 3-day food records. Daily energy intake (kcal), protein (g), carbohydrate (g), fat (g), and alcohol intake (g) were computed using the ESHA's Food Processor®. Participants were classified by percent weight loss, maintainers (≥38 %), and regainers (≤30 %). Daily carbohydrate consumption was greater in regainers (222 ± 84.3 g) compared with maintainers (162 ± 67.5 g), (P < 0.05). Thirty-seven percent of participants were not consuming the recommended amount of protein and 26% reported never taking vitamin supplements after surgery. Alcohol consumption was higher among regainers (18.5 ± 30.9 g) compared with maintainers (2.6 ± 6.5 g), (P < 0.05). Finally, 74% of the participants reported no contact with a Registered Dietitian, whereas 78 % were in contact with a health care professional once a year post-surgery. Differences were seen in carbohydrate intake and alcohol consumption between weight maintainers and regainers. These data suggest dietitians need to play a more active role in the long-term care of this medically complex population.
