Dietary restriction has been proposed as a method for extending lifespan. It can reduce oxidative stress damage, improve resistance, slow the aging process, and delay the development of age-related diseases in a variety of species. However, the mechanism by which this occurs remains unclear. Dietary restriction has been proven effective in epilepsy animal models in recent studies. A method called the ketogenic diet appeared to control epilepsy in clinical practice, but the emergence of anti-epileptic drugs slowed the development of diet therapy. Up to 20–40% of epilepsy patients ultimately become resistant to currently available anti-epileptic drugs. Once again, diet therapy is becoming a choice for treatment of epilepsy. This review discusses the history, animal research, and the mechanism of calorie restriction.
