Nutritional Ketosis in Parkinson's Disease - a Review of Remaining Questions and Insights

This review examines nutritional ketosis in Parkinson's disease. It states that three previous studies explored a ketogenic diet in Parkinson's cohorts and, while not conclusive, the data suggest non-motor symptom benefit. The authors review research on ketogenic diets, exogenous ketones, fasting and clinical studies, and identify remaining questions, including which symptoms are affected, what timescale is needed and how large an effect can be achieved, before a ketogenic diet can be recommended.
