This is a 16 week pilot study of the impact of a nutritionist led ketogenic diet (Ren-Nu) supplemented with the medical food KetoCitra on autosomal dominant polycystic kidney disease.
The goal of the Ren-Nu program aims to improve the metabolic health of ADPKD patients by implementing a plant-focused, kidney-safe, ketogenic diet supported by medical food KetoCitra®. It is a dietitian-led, online group program focused on ketogenic metabolic therapy with rolling recruitment .
For 12 weeks, participants will be remotely directed through the Ren-Nu program by an experienced renal dietitian where they will learn to implement diet and lifestyle changes by completing weekly web-based classes on nutrition principles and food preparation. A continuous glucose monitor (CGM) will be provided for use during the study. Additionally, they will use a smartphone application to track nutrient intake, self-monitor biomarkers, implement mindfulness practice, and participate in facilitated discussions to build community support. Each participant will meet remotely with the renal dietitian and complete laboratory safety monitoring throughout the program to tailor dietary recommendations for optimal compliance. The study will involve visits to the research institution, histories, physical examinations and laboratory work.

| Change in 24-Hour Urine Collection to track Lithogenic Risk | Change from baseline of 24-hour urine analytes in aggregate to assess lithogenic risk. The analytes will include calcium (mg/day), creatinine (mg/day), citrate (mg/day), oxalate (mg/day), uric acid (mg/day), sodium (mmol/day), chloride (mmol/day), magnesium (mg/day), ammonium (mmol/day), sulfate (mmol/day), phosphorus (mg/day), urea nitrogen (g/day), and urine pH. Measured via standard clinical laboratory assays. |
| Measure | Description | Time Frame |
|---|---|---|
| Change in health-related quality of life as assessed by the Quality of Life: Short-Form Health Survey 12 (SF-12v2) | Participants will complete the Quality of Life: Short-Form Health Survey 12 (SF-12v2) on Day 0 and Day 120. Scores are standardized by mean. A higher score indicates a better-than-average health-related quality of life, while a lower score suggests a below-average health-related quality of life. |
