Summary

This study from Yale University looked at what happens when teenagers with type 1 diabetes follow a very low carbohydrate diet for two weeks. Nineteen participants ate either a low-carb or standard diet to see how it affected their blood sugar levels and brain function. The goal was to understand if these diets are safe and helpful for young people managing diabetes.
