This pilot study examined whether ketogenic dietary interventions could help patients with autosomal dominant polycystic kidney disease (ADPKD), a genetic condition where fluid-filled cysts grow in the kidneys and liver over time. Previous animal studies suggested that ketogenic approaches might slow cyst growth, but this was the first study to test these interventions in humans with the disease.
The researchers studied 10 ADPKD patients with rapidly progressing disease. Half underwent 3 days of water fasting, while the other half followed a ketogenic diet for 14 days. Both approaches successfully put 90% of participants into ketosis (a metabolic state where the body burns fat for fuel instead of glucose), and participants found both interventions manageable in their daily lives.
The most significant finding was a 7.7% reduction in total liver volume, primarily due to changes in the non-cystic (healthy) liver tissue. However, kidney volume remained essentially unchanged, suggesting that longer interventions might be needed to see kidney-related benefits. The study demonstrated that ketogenic interventions are feasible and safe for ADPKD patients and may offer therapeutic potential.
While promising, this was a very small pilot study lasting only days to weeks. The liver volume reduction suggests metabolic interventions like ketogenic diets might play a supportive role in managing polycystic diseases, though patients should work with their healthcare providers before making significant dietary changes, especially those with kidney conditions.
