As a psychiatrist, I was trained to believe that severe mental illnesses like schizophrenia and bipolar disorder were lifelong and largely irreversible—caused by faulty neurodevelopment, the kindling effect, or some form of permanent brain damage.
But when a ketogenic diet can restore brain function in some individuals—even temporarily—it challenges everything we thought we knew.
It suggests the brain may not be irreparably broken. That healing is possible. That recovery isn’t just wishful thinking, but a real, physiological process we can support.
This opens up an entirely new paradigm for treating serious mental illness—one grounded in science, metabolism, and hope.
