Understanding early dietary adoption after bariatric surgery: A qualitative study using the theory of planned behaviour

Early dietary changes after bariatric surgery seem to be influenced by psychological, social, and physical factors beyond education. Future interventions should aim to incorporate strategies to reduce cognitive load, address competing social pressures, and account for the temporal aspects of health-protective behaviours. Theory-based interventions that integrate implementation intention techniques, social support optimisation, and temporal self-regulation strategies may enhance dietary adherence during this critical adaptation phase.
