Brief Summary

The goal of this trial is to evaluate blood sugar control in patients with type 1 diabetes when using a simple meal bolus strategy (small, medium, large meals) compared to carbohydrate counting when on a hybrid closed loop system. The main question it aims to answer are: What is the blood sugar time in range when using simple meal boluses versus carbohydrate counting? Participants will: Use the simple meal bolus plan for 4 weeks. Do precise carbohydrate counting for 4 weeks. Provide their continuous glucose monitor and pump data Take surveys about the experience of meal bolusing during the study
