Ketogenic diets were first introduced to help epilepsy sufferers and many studies have found them to be effective at treating this condition. There is also a lot of evidence that ketogenic diets can help people who have suffered brain injury.
A lot of brain disorders occur due to a lack of proper energy production . Ketones are seen by some scientists to be more efficient at producing energy than glucose, which could explain why ketogenic diets are so effective at treating these disorders.
What a lot of scientists are starting to claim is that the ketogenic diet may be effective as a neuroprotective. This means that the diet can help reduce the risk of certain brain disorders. A 2014 study found that “due to its neuroprotective capacity, the [ketogenic diet] may also hold potential benefit for the treatment of other neurological or neurodegenerative disorders” .
It’s early days yet, and people with neurological disorders shouldn’t immediately throw out their medication (definitely don’t do that). But this could be a real benefit in the future. Also, considering the more efficient production of energy, the ketogenic diet may help people think clearer, improve their memory, and their decision making skills.
