Keto diet tested for weight loss in type 1 diabetes: a 4-week crash diet study
NCT ID NCT07185555
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a very low-calorie ketogenic diet (600-800 calories per day) can help people with type 1 diabetes and obesity lose weight safely. Fourteen adults will follow the diet for 4 weeks while using an automated insulin pump. The main goal is to see how much weight they lose, and researchers will also check blood sugar control and safety.
