Century of Progress

A century of research and clinical experience has shown that restoring healthy brain metabolism with a metabolic intervention, like a ketogenic diet, can stop seizures in epilepsy.

A Mental or Metabolic Problem?

Growing scientific literature shows that, just like in seizure disorders, energy metabolism is impaired in those suffering from serious mental illness.

An Explosion in Research

Basic, translational and interventional clinical trials are underway around the world investigating the connection between brain metabolism, mitochondrial function and mental illness.

Emerging Evidence

Accumulating scientific literature indicates that reversing metabolic dysfunction can help heal the brain in serious mental illnesses like schizophrenia, bipolar disorder, major depression, and anorexia.

Clinical Trials

More than a dozen clinical trials of ketogenic therapy for serious mental illness are now completed or underway for conditions that include major depression, schizophrenia spectrum disorder, bipolar disorder, and anorexia.

Additional trials not listed here are in process for many other brain-based disorders, including anxiety, Alzheimer's disease, autism, post-traumatic stress disorder, and alcohol use disorder.
