More than 21,000 petition signers helped push a halted schizophrenia ketogenic-diet trial into peer review, giving the dispute a formal home in Frontiers in Public Health. The brief research report, International advocacy for ketogenic diet research in schizophrenia: insights from a public petition, was co-authored by Sidney L. Murray, Daniel J. O. Roche, Christopher M. Palmer, Shuo Chen, Hwiyoung Lee, Gopal Vyas and Heather A. Adams. It centers on a privately funded inpatient study of a medical ketogenic diet for schizophrenia that Palmer has said the Maryland Health Department stopped for no clear reason.
The campaign behind the paper was framed around protecting what Palmer called a “landmark research study for serious mental illness.” The petition carried the title Help us protect a landmark research study for serious mental illness, and its signature count climbed past 21,000 before the effort culminated in publication. The result is not a verdict on keto for schizophrenia, but it does turn a once-anecdotal fight over a stopped trial into something the psychiatric and keto worlds can point to in the literature.
That matters because the idea did not come out of nowhere. PubMed indexes a 2019 paper, The ketogenic diet and remission of psychotic symptoms in schizophrenia: Two case studies, and a 2024 pilot trial, Ketogenic Diet Intervention on Metabolic and Psychiatric Health in Bipolar and Schizophrenia: A Pilot Trial. Those titles do not prove the diet works for schizophrenia, but they show the question has moved from online speculation into formal clinical inquiry.
Palmer’s work has also had visible institutional support. McLean Hospital posted in April 2019 about his paper suggesting a ketogenic diet may help some psychiatric symptoms, and the hospital’s Metabolic and Mental Health Program now includes educational videos on the ketogenic diet in medicine and psychiatry. For readers who have followed medical keto as a metabolic tool first and a mental-health frontier second, the new paper adds a documented advocacy trail, a named trial leader in Deanna L. Kelly, PharmD, BCPP, and a clearer paper trail for future research. What it does not add is proof that the diet treats schizophrenia.
