Combination of GLP‐1 receptor agonists and behavioural treatment in type 2 diabetes elicits synergistic effects on body weight: A retrospective cohort study

AIMS: Intensification of type 2 diabetes (T2DM) treatment with GLP-1 receptor agonists (GLP-1RAs) promotes weight loss. We aimed to determine the synergistic effect of behavioural programmes on body weight on top of GLP-1RA treatment. MATERIALS AND METHODS: We retrospectively analysed the time course of 328 individuals with T2DM starting GLP-1RA treatment because of insufficient metabolic control. In 29, a structured programme of elementary nutritional counselling was also implemented (elementary nutritional education [ENE]-5 group sessions), whereas 53 entered a programme of cognitive-behavioural treatment (CBT-12 group sessions). Both programmes were completed within 6 months of switching to GLP-1RAs. Data of body weight and metabolic control were followed up to 2 years as part of regular follow-up. Weight loss targets (≥10% and ≥5%) and metabolic target (HbA1c < 7%) were analysed by Cox regression model in comparison with standard care (SC, N = 244). No differences in metabolic control were detected between groups. CONCLUSIONS: Initiation of GLP-1RA treatment provides an opportunity for addressing patients' needs of weight control. By producing initial weight loss, patients' motivation and self-efficacy are expected to increase and adherence to long-term lifestyle changes might be more easily attained.
