Keto Diet May Help Protect Against Multiple Brain Diseases, Study Finds

A new review found the keto diet may help protect against brain diseases by changing how the body uses energy.

Researchers say ketosis could reduce inflammation, improve cellular cleanup, and affect pathways linked to Alzheimer’s, Parkinson’s, and Huntington’s disease.

Most of the evidence comes from animal studies, so stronger human clinical trials are still needed.

The review also notes the diet can be difficult to follow long term and may cause side effects.
