Dietary Habits and Body Weight at Long-Term Following Biliopancreatic Diversion

This study aims to evaluate the role of simple carbohydrates and alcohol intake in determining weight of stabilization at long-term following malabsorptive bariatric surgery. Sixty patients at more than 2 years following biliopancreatic diversion (BPD) were submitted to an alimentary interview for evaluating the daily consumption of simple sugar, fruits, ice-cream, sweets, and caloric and alcoholic beverages. Eating behavior was assessed by Three Factors Eating Questionnaire. The mean estimated daily energy consumption intake was 2,852 kcal, with a mean daily intake of simple carbohydrates of 89 g that represented 12% of the total energy intake. The current body weight was positively and independently related to the preoperative body weight and to simple carbohydrate and alcohol intake and negatively related to physical activity, while no association with total energy consumption and eating behavior was found. These findings confirm that following BPD the body weight is independent of energy intake and eating behavior. Furthermore, these data suggest that in post-BPD subjects the simple carbohydrates and alcohol absorption is fully preserved, and that the operated subjects could regulate their body weight by reducing simple carbohydrates and alcoholic intake and increasing physical activity.
