Ketogenic Diet Could Shield the Brain From Neurodegenerative Diseases, Review Finds

A new review finds the ketogenic (keto) diet could offer neuroprotection against diseases like Alzheimer's, Parkinson's, and Huntington's by altering energy metabolism and increasing ketone use, which may reduce inflammation, boost autophagy, and improve gut-brain health; though most supporting studies are in animals, long-term safety, practicality, and clinical efficacy in people remain uncertain, and more trials are needed.
