Feasibility of a protein-enriched diet after laparoscopic adjustable gastric banding: Results from a pilot intervention

SummaryBackground & aimsWeight loss following laparoscopic adjustable gastric banding (LAGB) is variable. Increased protein intakes may promote optimal weight and body composition outcomes during weight loss. This study aimed to determine the feasibility of a protein-enriched diet after LAGB and to report pilot data findings.MethodsLAGB patients (n = 47) were allocated to follow a protein-enriched diet or usual care for six months after surgery. Weight, body composition and dietary intake were measured at baseline, three, six and 12 months.ResultsCompliance with the protein-enriched diet was problematic. No differences in protein intake, weight or body composition were observed between the intervention and usual care groups. Relative protein intake for the study sample as a whole was not a significant predictor of weight or body composition at any time point.ConclusionsFeasibility of increasing protein intake from usual foods and a dietary supplement following LAGB was limited by compliance difficulties. This may negate any potential utility of a protein-enriched diet after LAGB. Further research is required to establish evidence-based guidelines for protein intake following LAGB and to determine methods to enhance compliance with dietary recommendations.Clinical trial registration number: ACTRN 12609000258257.
