Total reversal of weight loss from adjustable gastric banding surgery associated with excessive intake of energy dense liquid and solid foods: A case report

Summary We report excessive binging and total reversal of weight loss in a patient after adjustable gastric banding surgery (AGBS). A 42-year-old female who underwent AGBS 4 years earlier was randomized to a diet group in a study on exercise training. The patient was on therapy for pre-diabetes and depression. She weighed 115kg pre-surgery, lost 27.3kg post-surgery, and weighed 117.3kg at the start of the study. Her energy intake, assessed by 3-day food record, was 14,096kcal/d at the beginning of the study of which 3086kcal/d was from liquid and 7273kcal/d from solid energy dense foods. The patient reported that the liquid foods facilitated binging on solid foods despite gastric band adjustments. Following intensive dietary counseling for 5 weeks, her reported energy intake decreased to
