Read our Diabetes Mellitus, Type 1 research guide →This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This is a 12-week study testing a ketogenic diet—a very low-carbohydrate diet—in people with type 1 diabetes. Some smaller studies and case reports suggest this diet might reduce blood sugar swings, lower daily insulin requirements, and improve blood sugar control. However, this will be one of the first rigorous studies to test whether the treatment is safe and effective in type 1 diabetes over a longer period.
While some people with type 1 diabetes have reported benefits from very low-carb eating, doctors worry about potential risks like dangerously low blood sugar, a serious condition called diabetic ketoacidosis, and other health effects. This study exists to rigorously test whether the benefits outweigh the risks and to understand how this approach affects people's overall health and quality of life.

You will be randomly assigned to eat either a very low-carbohydrate diet (less than 50 grams of carbs per day) or a standard diabetes-recommended diet for 12 weeks. Both groups will receive prepared meals delivered to you, so you don't have to plan meals yourself. Throughout the study, you'll wear a continuous glucose monitor to track your blood sugar, and the research team will monitor your health, insulin use, and how you're feeling with regular check-ins.
