Nutritional ketosis or the Ketogenic Diet (KD) - "keto" for short – was originally developed as a treatment for epilepsy in children in the 1920s. As such, the KD has always had its roots as a treatment for mental disorders.

The keto diet has been scientifically proven to reduce markers for cognitive decline such as pain and inflammation, as well as improve mitochondrial respiration (helping our cells breath) and reduce oxidative stress.

The diet is now being studied for its efficacy in the treatment of a wide range of cognitive diseases such as Alzheimer’s disease (AD), Parkinson's disease (PD) and depression, due to its neuroprotective effects.

In this article, we shall take a closer look at the ketogenic diet and investigate its implications for brain health specifically.
