Continuous glucose monitoring and other new technologies are altering the landscape of type 1 diabetes nutritional management. The widespread use of these technologies has been accompanied by consumer and health professional interest in the impact of different macronutrients and a demand for clinical explanations for aberrant postprandial glycemic patterns. To achieve target postprandial glycemia, current clinical practice involves adjustment of the insulin dose for the carbohydrate content of the meal. However, despite accurate carbohydrate counting and insulin dose calculation, dysglycemia may occur. Identifying the contribution of other macronutrients to postprandial glycemic variability, and strategies to optimise dosing for fat and protein has been the focus of our research at the John Hunter Childrens Hospital in Newcastle, Australia. The objectives of this presentation are to: 1) outline steps to identify the impact of fat and protein from continuous glucose monitoring traces, 2) highlight how best to bolus for different macronutrients, encompassing strategies for multiple daily injection, insulin pump and hybrid closed loop therapies, and 3) discuss macronutrient intake in the context of future challenges of obesity and cardiovascular risk in youth with type 1 diabetes.
