There is some evidence to suggest that a ketogenic diet may improve brain function in certain individuals. The ketogenic diet is thought to enhance brain function by providing an alternative fuel source for the brain in the form of ketones, which are produced when the body burns fat for energy.
Research has shown that a ketogenic diet may improve cognitive function in people with certain neurological conditions, such as epilepsy, Alzheimer’s disease, and Parkinson’s disease. It may also improve memory and learning in healthy individuals.
One theory behind the potential cognitive benefits of a ketogenic diet is that it reduces inflammation in the brain, which can contribute to cognitive decline. Additionally, the diet may increase the production of brain-derived neurotrophic factor (BDNF), a protein that supports the growth and survival of brain cells.
