Harvard psychiatrist debunks RFK Jr.'s claim that keto 'cures' schizophrenia

A Harvard psychiatrist has spoken out after Robert F. Kennedy Jr. claimed the keto diet could 'cure' schizophrenia. Dr. Christopher M. Palmer, a scholar in the field, clarified that his research does not support such a claim. The debate comes amid growing interest in dietary treatments for mental health conditions.

The two met in September 2024 at a nutrition roundtable hosted by Senator Ron Johnson. Dr. Palmer, a patient-centered researcher, has studied the diet's effects on psychiatric symptoms but stresses the evidence remains limited.

Dr. Palmer first explored the ketogenic diet as a weight-loss tool for a patient with schizoaffective disorder. After two months, the patient reported fewer hallucinations and delusions. This unexpected outcome led to further investigation.

In 2019, he documented two schizophrenia patients who achieved full remission of symptoms on the diet. Both were able to stop antipsychotic medications. However, Dr. Palmer avoids the term 'cure' and describes the results as remission for some individuals.

Interest in the approach has surged, with thousands of patients seeking his guidance. Yet, few clinicians currently offer the treatment. The American Psychiatric Association considers it controversial, citing a lack of strong, consistent evidence.

Dr. Paul S. Appelbaum, a psychiatry professor, called the existing research 'very, very preliminary.' Around 20 trials on ketogenic therapies for psychiatric disorders are underway, including two randomised control trials for schizophrenia. Still, no major institutions have confirmed plans for large-scale studies.

Dr. Palmer has repeatedly stated that while some patients respond well, the diet is not a universal solution. He cautions against overstating its benefits without further research.

The discussion around ketogenic diets for mental illness continues, with experts urging more rigorous studies. Dr. Palmer's work shows promise for certain cases but does not support claims of a definitive cure. For now, the approach remains experimental, with limited clinical adoption and ongoing debate in the medical community.
