Guidelines for Post-exercise Dietary Intake in T1DM

November 14, 2013 updated by: Northumbria University

The Metabolic and Glycaemic Responses to Changes in the Glycaemic Index of the Meal Consumed After Performing Evening Exercise in Type 1 Diabetes Mellitus

The investigators hypothesise that manipulating the glycaemic index of the meal after exercise and before sleep will help prevent Type 1 diabetes individuals experiencing hypoglycaemia.
