AIMS: Weight gain upon insulin initiation is opposite to clinical goals in diabetes management. This trial aimed to determine the impact of modest dietary intervention on weight change and examine weight change in baseline body mass index strata when initiating once-daily insulin detemir (IDet) in overweight or obese insulin-naïve individuals with type 2 diabetes (T2D). METHODS: DIET (Impact of Dietary Intervention on Weight Change in Subjects With Type 2 Diabetes) was a 26-week, randomized, treat-to-target, stratified, controlled, open-label, multinational trial. Subjects were randomized 1 : 1 to either the IDet group, which received basic dietary and physical exercise advice at baseline, or the Diet+IDet group, which had additional dietary consultations with a certified dietician (three face-to-face meetings, three phone contacts). RESULTS: Mean estimated change in body weight from baseline ± standard error (SE) was -1.05 ± 0.23 kg for Diet+IDet and -0.56 ± 0.23 kg for IDet alone. Estimated mean difference was 0.49 kg (95% confidence interval: -0.15; 1.13, p = 0.132). Glycaemic control, measured by haemoglobinA1c (HbA1c) and fasting plasma glucose, improved similarly in both groups. Both groups reported variable reductions in caloric intake and overall physical activity levels. No difference in hypoglycaemia rates between groups was observed. CONCLUSION: This study suggests that a modest dietary intervention plus basic lifestyle advice, compared with basic lifestyle advice alone, resulted in similar weight change, efficacy, safety and tolerability when initiating IDet once daily in overweight or obese insulin-naïve individuals with T2D.
