Researchers are testing whether daily calorie restriction can slow kidney enlargement in adults with autosomal dominant polycystic kidney disease, an inherited condition that causes kidney cysts. The trial enrolled 120 adults with overweight or obesity and assigned them to either a behavioral weight loss program or standard dietary advice for two years. MRI scans will track changes in kidney size relative to height. Participants averaged 45 years old; 84 were women and 36 were men. This paper reports the study plan and starting characteristics, not whether the intervention works. Completion of the final study cohort is expected in July 2027. The research could inform dietary management, but it does not yet justify calorie restriction as a treatment for kidney cyst growth. This summary is based only on the abstract.
