WHAT IT’S REALLY ABOUT
Chris Palmer on ketones, mitochondria, and a new psychiatry model
- Dr. Christopher Palmer presents a “brain energy theory” linking mental illness to metabolism and mitochondrial function, positioning ketogenic diets and related strategies as potential tools in psychiatric treatment.
- He critiques DSM-5 diagnostic categories as symptom-based syndromes with major heterogeneity and comorbidity, arguing they don’t map cleanly to single causes, including at the genetic level.
- He recounts striking clinical anecdotes—most notably a woman with decades of schizophrenia symptoms whose condition reportedly remitted after starting a ketogenic diet for weight loss—and describes similar observations in other patients.
- He explains how ketosis may influence mood, cognition, and sleep, while warning that decreased sleep and hyperexcitability during keto-adaptation can pose risks, especially in vulnerable individuals.
- He argues many psychiatric medications can impair metabolism while still reducing symptoms, and urges careful, clinician-guided use of metabolic interventions alongside (not instead of) existing treatments, with slow, supervised tapering if appropriate.
IDEAS WORTH REMEMBERING
5 ideasA ketogenic diet coincided with a long-standing schizophrenia remission in a documented case.
He describes a 70-year-old woman (Doris) with decades of hallucinations, delusions, repeated suicide attempts, and heavy medication exposure who tried a ketogenic diet for weight loss and reported rapid symptom reduction, culminating in full remission and discontinuation of psychiatric medications, with sustained remission for years.
He argues DSM-5 labels are clinically useful but weak at capturing underlying causes.
He says DSM-5 categories are syndromes (constellations of symptoms) rather than known disease entities, and highlights two core issues: heterogeneity (same diagnosis can look very different across people) and comorbidity (people frequently meet criteria for multiple diagnoses). He also notes that genetics do not map neatly to single DSM categories, and says the NIH moved away from DSM categories as research constructs.
The episode’s unifying claim is that mental disorders can be viewed through brain energy and mitochondrial function.
He frames metabolic psychiatry as an emerging field, but emphasizes a broader “brain energy theory” that links mental and physical health through metabolism and mitochondria. He repeatedly returns to mitochondria as a common node connecting diverse influences (stress, trauma, hormones, neurotransmitters, inflammation).
Ketosis-related mood and sleep changes can be powerful—and sometimes destabilizing.
He reports that ketosis can reduce sleep needs and elevate mood/energy, and warns that sleep reduction during keto-adaptation can become problematic—especially for people with histories of psychosis or bipolar-spectrum symptoms—sometimes resembling hypomania/mania. He offers an evolutionary speculation: ketosis may signal scarcity and increase drive/alertness to seek food.
He portrays ketosis as potentially therapeutic but not universally benign, especially during adaptation.
He describes metabolically compromised cells as potentially becoming underactive or hyperexcitable, and says adding ketones can sometimes increase hyperexcitability early on, potentially presenting as anxiety, agitation, OCD-like symptoms, psychosis, or in extremes, seizures. He distinguishes these risks from diabetic ketoacidosis.
WORDS WORTH SAVING
5 quotesFrom the ages of 68 to 70, she tried to kill herself at least six times and was hospitalized for those suicide attempts.
— Dr. Christopher Palmer
Within months, all of her symptoms of schizophrenia were in full and complete remission. Within six months, she was off all psychiatric medications and remained in full and complete remission.

My futile attempts to save you from the ravages of mental illness lit a fire in me that burns to this day. I'm sorry I didn't figure this out in time to help you. May you rest in peace.
— Tim Ferriss
DSM-5 is kind of the bible of psychiatry, and it's what all mental health professionals have to use to make a diagnosis.

The single biggest pitfall is all the keto labeled junk food.
