RESUMEN
Aim: Evidence suggests low-carbohydrate diets (LCHF) may assist in treating neurodegenerative diseases such as Parkinson's disease (PD); however, gaps exist in the literature. Patients & methods: We conducted a small 24-week pilot study to investigate the effects of an LCHF diet on motor and nonmotor symptoms, health biomarkers, anxiety, and depression in seven people with PD. We also captured patient experiences during the process (quality of life [QoL]). Results: Participants reported improved biomarkers, enhanced cognition, mood, motor and nonmotor symptoms, and reduced pain and anxiety. Participants felt improvements enhanced their QoL. Conclusion: We conclude that an LCHF intervention is safe, feasible, and potentially effective in mitigating the symptoms of this disorder. However, more extensive randomized controlled studies are needed to create generalizable recommendations.

RESUMEN
Aim: To evaluate a low carbohydrate/healthy fat/ketogenic diet (LCHF/KD) on symptoms, depression, anxiety and biomarkers in adults with Parkinson's disease (PD). Patients & methods: 16 adults ages 36-80 with PD participated in the intervention for 12 weeks. The study provided pre-post-study comparisons of biomarkers, weight, waist measurement, united Parkinson's Disease Rating Scale (UPDRS), Parkinson's Anxiety Scale (PAS) and Center for Epidemiologic Studies Depression Scale Revised-20 (CESD-R-20) Depression Scale. Results: Although LCHF/KD improves blood glucose in diabetes and seizure control in epilepsy, research gaps exist in this dietary intervention in PD. Statistically, significant improvements occurred in several measurements, PAS scores and Part I of the UPDRS. Conclusion: The LCHF/KD shows positive trends with improvements in biomarkers and anxiety symptoms. Further research is needed to evaluate dietary interventions for PD.
