Abstract
Although the benefits of preoperative weight loss and adequacy of dietary patterns in bariatric surgery is wellrecognized the nutritional strategies in the preoperative period have been scarcely investigated We aimed to evaluate the impact of intensive and standard nutritional interventions on body weight energy intake and eating qualityThis is a retrospective study in which 32 patients undergoing intensive nutritional intervention with lowcalorie diet 10 kcal/kg and biweekly visits were pairmatched by age sex and body mass index with 32 patients under a standard nutritional intervention based on a general dietary counseling Twentyfourhour food recall was used to assess energy intake and to derive healthy eating index HEI The followup preoperative period varied from 8 to 16 weeksWeight loss was observed in 72 of the patients from the intensive intervention group and 75 of the patients from the standard intervention group According to the mixed model analysis time effect on weight loss in both groups was significant P = 00002 however no difference was found between the intervention groups P = 071 The time effect was significant in both groups for energy intake reduction as well P 00001 but no difference was found between the intervention groups P = 025 Improvement of eating quality was expressed by the nutrient score of the HEI that increased significantly overtime P = 002 also without distinction between the groups P = 061
