Original abstract
BackgroundCurrent clinical research suggests that the ketogenic diet (KD) intervention can alleviate Parkinson's disease (PD) symptoms. However, the underlying mechanisms remain unclear. This pilot study explored the potential link between KD-induced clinical improvements and gut microbiota alterations.MethodsWe engaged 27 PD patients in a 12-week ketogenic dietary trial (16 completed) and employed 16S rRNA sequencing to analyze gut microbiota differences compared to 27 healthy controls.ResultsBaseline analysis revealed distinct dysbiosis in PD patients, characterized by increased abundance of Enterobacteriaceae. Following the 12-week intervention, patients exhibited significant improvements in both motor (MDS-UPDRS Part III, p < 0.001) and non-motor symptoms (NMSS, p < 0.0001). These clinical improvements were accompanied by specific microbial shifts: a significant increase in Enterococcus and Synergistota, and a decrease in Alloprevotella.ConclusionThese findings suggest that the therapeutic effects of the ketogenic diet in PD are associated with specific remodeling of the gut microbiota, particularly the enrichment of potential beneficial taxa and reduction of pro-inflammatory genera.Clinical trial registrationhttps://www.chictr.org.cn/index.html, Unique Identifier: ChiCTR2100045394.
