The Dietary Education Trial in Carbohydrate Counting (DIET-CARB Study in Type 1 Diabetes

The study is designed to evaluate two different dietitian-led self-management approaches in carbohydrate counting compared to routine dietary care (control) on glycaemic control in adult patients with type 1 diabetes: 1. The basic carbohydrate counting concept aims at improving carbohydrate counting accuracy and day-to-day consistency of carbohydrate intake (the BCC intervention) 2. The advanced carbohydrate counting concept aims at improving prandial insulin dose accuracy using an automated bolus calculator (the ABC-ACC intervention) The main hypothesis is that structured training and education in either the BCC concept or the ABC-ACC concept will reduce HbA1c or the average glucose variability more than routine dietary education.
