U.S. health and human services secretary Robert F. Kennedy, Jr.’s claim that a high-fat, low-carbohydrate diet may cure certain psychiatric conditions is misleading and not backed by evidence, experts say.
At an event in Tennessee on Wednesday touting new nutrition guidelines that emphasize eating a diet rich in red meat, whole milk and animal fats, Kennedy said that a doctor at Harvard had “cured schizophrenia using keto diets” and that there were studies showing people “lose their bipolar diagnosis by changing their diet.”
In his speech, Kennedy mentioned a “Dr. Pollan” at Harvard, but there appears to be no such person there or elsewhere who has studied the keto diet and its effect on schizophrenia; he may have meant to cite Christopher Palmer, an assistant professor of psychiatry at Harvard Medical School.
Palmer co-authored a 2025 study that reviewed the evidence for the ketogenic diet as a possible treatment for schizophrenia. It found that small pilot studies suggested that the diet may improve some symptoms of the disorder in some people. But Palmer emphasizes that other people with the condition may not see any improvement with the keto diet."
