Testing a moderate carbohydrate diet for children with type 1 diabetes

This trial is testing whether eating a moderate carbohydrate diet helps children and teens with type 1 diabetes keep their blood sugar in a healthy range while using a hybrid closed-loop insulin pump (an advanced pump that automatically adjusts insulin delivery). The study wants to understand if eating fewer carbohydrates—compared to a traditional diet—can improve blood sugar control and be practical for young people to follow.

Although doctors have used carbohydrate restriction to help manage type 1 diabetes for a long time, we don't yet know clearly how helpful it is for children, especially when combined with modern insulin pump technology. This study fills that gap by testing whether this diet approach works alongside these new pumps and whether it's realistic for young people to stick with.
