Dr. Chris Palmer proposes that mitochondrial dysfunction is the unifying root of both mental disorders (depression, schizophrenia, autism) and metabolic diseases (obesity, diabetes, cardiovascular disease), shifting the paradigm from neurotransmitter-centric models.

The ketogenic diet, originally an epilepsy treatment, can induce remission in treatment-resistant bipolar, schizophrenia, and depression by improving mitochondrial health, mitophagy, and brain energy metabolism.
3
Undiagnosed vitamin deficiencies (B12, folate, iron) are widespread and can cause severe psychiatric symptoms; a newly discovered autoimmune condition (anti-CD320) blocks B12 transport into the brain, offering a treatable cause for some 'incurable' cases.

While vaccines can trigger inflammatory stress that may tip vulnerable individuals toward neurodevelopmental disorders, rising obesity and diabetes in parents are far stronger drivers of skyrocketing autism and ADHD rates—metabolic health of prospective parents is a critical, modifiable target.

Intermittent Fasting / Fasting-Mimicking Diet
WhatPeriodic caloric restriction, either via time‑restricted eating (e.g., 8‑hour feeding window) or multi‑day low‑calorie patterns (5 days of ~600 kcal/day a few times per year).
WhenDaily time‑restricted eating can be maintained long‑term; multi‑day fasting‑mimicking cycles can be done seasonally (e.g., 2-4 times per year) for a metabolic reset.
DoseTime‑restricted: 16:8 or 14:10 daily. Fasting‑mimicking: 5‑day cycles of 600 kcal (plant‑based, low protein) as studied by Valter Longo.
For whomHealthy individuals looking to optimize mitochondrial function; may also benefit those with mild metabolic or mood issues. Not for underweight or malnourished individuals.
WhyFasting states stimulate mitophagy and mitochondrial biogenesis similarly to ketogenic diets, improving metabolic health markers and potentially extending healthspan.
CaveatsMost intermittent fasting studies do not control for diet quality when eating, leading to mixed results. Time‑restricted eating alone may not provide full benefits if the eating window includes ultra‑processed foods. Multi‑day fasts require monitoring and are not suitable for pregnant women or those with eating disorders.
Palmer acknowledges that fasting has been a part of healing traditions for millennia and likely persisted because of real physiological benefits. He cites Valter Longo’s ProLon fasting‑mimicking diet, which has published data showing improvements in metabolic biomarkers and possible longevity effects. He notes the debate between moderate intermittent fasting (like 16:8) and more prolonged fasts, emphasizing that without controlling for what people eat, studies are confounded. Nonetheless, he believes brief ketogenic or fasting cycles can give the mitochondrial house-cleaning boost without requiring a permanent restrictive diet.
Mechanism
Caloric restriction and low‑nutrient states activate AMPK and inhibit mTOR, which triggers autophagy and mitophagy pathways. The drop in insulin and glucose shifts liver to ketogenesis, providing ketones that signal mitochondrial biogenesis and reduce oxidative stress.
We have a long history in multiple cultures on Earth for thousands of years, fasting has been part of healing rituals. I actually think millennia of humans were not all stupid idiots, and some people along the way actually noticed this seems to do something useful.
Vitamin B12 and Folate Assessment with Deficiency Correction
WhatMeasure serum B12, folate, and if indicated methylmalonic acid/homocysteine; treat low levels with oral supplementation if absorption normal, or intramuscular injections if autoimmune or absorption issues; for suspected central deficiency, consider spinal fluid analysis and high‑dose B12 injections plus immunosuppression.
WhenAt annual physicals, before conceiving, or immediately when neuropsychiatric symptoms emerge unresponsive to standard treatment.
DoseOral: 1000–2000 mcg/day cyanocobalamin or methylcobalamin for dietary deficiency. Injection: 1000 mcg intramuscular weekly or as clinically indicated. In autoimmune central deficiency, high doses (regimen not specified) combined with immunosuppressives.
For whomVegans, vegetarians, people on metformin or oral contraceptives, elderly with pernicious anemia, and patients with unexplained neuropsychiatric symptoms.
WhyB12 is essential for mitochondrial function; deficiency leads to demyelination, neurotransmitter disruption, and can cause permanent brain damage if untreated.
CaveatsNormal serum B12 does not rule out deficiency—up to 6% of the population may have anti‑CD320 central deficiency with normal blood levels. Spinal tap is required to confirm central deficiency. High‑dose B12 without medical supervision can mask underlying causes.
Palmer details a public health crisis: iron deficiency in 40% of US girls aged 12–21, which he ties to the sharp post‑pubertal rise in depression and anxiety in females. He then focuses on B12, noting that in India, where vegetarianism is common, 50% of the population is deficient. He distinguishes classic dietary or pernicious‑anemia B12 deficiency from the newly discovered autoimmune form against the CD320 receptor that blocks B12 at the blood‑brain barrier, causing devastating neuropsychiatric presentations even when serum levels are normal. He advocates for clinicians to aggressively search for these deficiencies rather than prescribing lifelong psychiatric medication. For the central deficiency, the protocol is still nascent but involves immunosuppression and high‑dose B12 to flood the brain.
Mechanism
B12 (cobalamin) is a cofactor for methionine synthase (homocysteine remethylation) and methylmalonyl‑CoA mutase. These reactions are critical for myelin synthesis, mitochondrial ATP production, and neurotransmitter metabolism. Without B12, homocysteine accumulates, causing vascular damage and oxidative stress. In the central form, CD320 is the receptor on choroid plexus epithelium that transports B12 into CSF; autoantibodies block it, starving the brain of B12 while systemic levels remain normal.
When the researchers tested their cerebrospinal fluid, they had almost no B12 in their central nervous system. … We now have a brand new form of autoimmune B12 deficiency that targets a protein called CD320 which transports vitamin B12 across the blood‑brain barrier.
Also said
“The challenge with B12 deficiency is that the neurological damage can become permanent. If this is not recognized and identified early enough, people can be permanently injured.”— Urgency of testing and treatability.
Creatine Supplementation for Brain Energy
WhatTake creatine monohydrate, typically 3–5 grams daily, to restore or enhance brain creatine levels.
WhenDaily, with food or after a loading phase. Can be used long‑term.
Dose3–5 g/day maintenance dose; loading of 20 g/day for 5–7 days optional. Duration: chronic if indicated.
For whomVegans, vegetarians, and people with neuropsychiatric conditions who show low brain creatine on MRS or have poor response to standard treatments. Not a first‑line supplement—lifestyle must be optimized first.
WhyCreatine acts as a phosphate shuttle inside mitochondria, critical for ATP regeneration in high‑energy demand tissues like brain. Low brain creatine is associated with depression, schizophrenia, and Alzheimer’s.
CaveatsNot a ‘magic pill’; placebo‑controlled trials are small and underpowered because creatine is off‑patent. High doses may cause gastrointestinal discomfort. Will not compensate for poor diet, sleep, or substance abuse.
Palmer explains creatine’s role in mitochondrial energy metabolism: within mitochondria, creatine combines with ATP to make phosphocreatine, which then travels to sites of energy demand (synapses, ribosomes) to rapidly regenerate ATP. Brain imaging using MRS shows that vegans and vegetarians have lower brain creatine, and people with schizophrenia, depression, and Alzheimer’s also show lower levels. Small randomized controlled trials suggest creatine can augment antidepressants and improve cognition in mild cognitive impairment. Palmer wants larger trials but notes no profit incentive exists. He emphasizes that creatine will not fix the damage from an unhealthy lifestyle and that the six pillars must come first.
Mechanism
Creatine + ATP → phosphocreatine + ADP (catalyzed by mitochondrial creatine kinase). Phosphocreatine diffuses to cytosolic sites where it donates phosphate to ADP, regenerating ATP. This buffer sustains ATP during synaptic transmission, protein synthesis, and ion pumping, protecting against energy failure and excitotoxicity.
Creatine goes into the mitochondria and there it gets combined with ATP to become phosphocreatine, and then it leaves the mitochondria and goes to places in the cell where energy is needed, like a synapse or a ribosome.
Also said
“People with neuropsychiatric disorders—schizophrenia, Alzheimer’s disease, depression—have been found to have lower levels of creatine than people who do not have those disorders.”— Epidemiological evidence linking creatine to brain health.
Methylene Blue as Mitochondrial Electron Shuttle (Adjunctive Use)
WhatUse low‑dose methylene blue (pharmaceutical grade, often IV or oral) to act as an electron acceptor/donor, reducing oxidative stress in dysfunctional mitochondria.
WhenFor treatment‑resistant neuropsychiatric conditions when lifestyle and other interventions insufficient; currently experimental.
DosePalmer does not specify exact dose; mentions risk of serotonin syndrome at high doses and that too‑little vs. too‑much matters. Typical experimental oral doses range from microgram to milligram amounts.
For whomPatients with severe, refractory depression, bipolar, schizophrenia, Alzheimer’s, where other mitochondrial interventions have not yielded full remission.
WhyIn conditions with electron leak and high reactive oxygen species (oxidative stress), methylene blue can capture stray electrons, preventing damage and improving ATP production.
CaveatsNarrow therapeutic window; too little may be ineffective, too much can cause reductive stress identical to the oxidative stress it intends to fix. Can cause serotonin syndrome if combined with SSRIs or other serotonergics. Stains urine, teeth, tongue blue. Must use pharmaceutical‑grade product; fish‑tank cleaners are toxic.
Palmer discusses methylene blue’s history as a fish‑tank cleaner and its recent popularity after a video of RFK Jr. putting it in water. He explains it is exclusively a mitochondrial agent: it can accept and donate electrons, shuttling them within the electron transport chain. When mitochondria are damaged and electrons leak, they form reactive oxygen species (oxidative stress). Methylene blue can step in to take those wayward electrons, reducing oxidative damage. However, Palmer warns that some disorders also involve reductive stress (excess electrons), so methylene blue could in theory tip the balance the wrong way if overdosed. He is interested in starting to use it in controlled ways for patients who fail all other metabolic treatments.
Mechanism
Methylene blue is a redox cycler. It accepts electrons from NADH or other donors and can transfer them directly to cytochrome c, bypassing Complex I/III blockades. This restores mitochondrial membrane potential and ATP production while reducing electron leakage and ROS generation. However, overdosing can over‑reduce the electron chain, causing reductive stress and impaired ATP synthesis.
Personal experience
Palmer does not take methylene blue personally and has not yet used it in patients, but is open to future use.
Methylene blue is primarily, exclusively a mitochondrial agent. It is an electron acceptor and donor. … It can come in and take some of these wayward electrons and prevent them from creating reactive oxygen species.
Also said
“You can have too little and too much, same with methylene blue. You don't want to accept too many electrons … that too has been found in people with schizophrenia and bipolar disorder—it’s about dysregulated balance between oxidative and reductive stress.”— Caveat that mechanism is double‑edged.

Emerging autoimmune central vitamin B12 deficiency (anti-CD320)
Mid-episode, around 60-70 minutes
A newly discovered antibody against the CD320 receptor prevents vitamin B12 from crossing the blood-brain barrier, causing severe neuropsychiatric symptoms even when peripheral blood B12 levels are normal.
Why this matters: This may explain a significant fraction of 'treatment-resistant' psychiatric and neurological disorders that are actually reversible with high‑dose B12 injections or immunosuppression.
Background
Classical B12 deficiency from diet, pernicious anemia, or drug interactions (metformin, contraceptives) is well known. The new finding reveals a forme fruste where the brain is specifically starved of B12 while systemic levels look fine, misleading clinicians.
Palmer describes recent publications identifying anti‑CD320 antibodies that block B12 transport across the blood-brain barrier. In initial cohorts, about 6% of healthy controls had the antibody, rising to 20% in patients with neuropsychiatric lupus and up to 50% in those with demyelinating conditions of unknown etiology. Standard serum B12 is normal in these individuals, but cerebrospinal fluid B12 is nearly zero. Treatment with immunosuppressive agents and high‑dose B12 injections has led to symptom reversal in some cases. Palmer is working to study this in psychiatric populations, seeing it as a concrete, treatable cause hidden under labels like schizophrenia or chronic depression.
When the researchers tested their cerebrospinal fluid, they had almost no B12 in their central nervous system. So that requires a spinal tap... and they ended up treating some of these people with immunosuppressive agents to reduce this autoimmune condition and high dose vitamin B12, and some of the people had reversal of symptoms.
Also said
“They sampled just a general healthy control and about 6% of those people have this antibody.”— Indicates the potential large scale of currently missed cases.
Metabolic syndrome in parents as a primary driver of rising autism and ADHD rates
Late episode, around 80-90 minutes
While vaccines dominate the public debate, the obesity and diabetes epidemic in men and women of reproductive age may be the largest factor behind skyrocketing neurodevelopmental disorders, with maternal obesity doubling risk and combined obesity+diabetes quadrupling it.
Why this matters: Redirects the conversation from a contentious single-factor hypothesis (vaccines) to a modifiable, multi‑factorial metabolic root cause that aligns with the mitochondrial theory.
Background
Autism and ADHD rates have surged, often attributed to better diagnosis, environmental toxins, or vaccines. Palmer acknowledges the role of inflammation but argues that the metabolic health decline—only 7% of Americans are metabolically healthy—likely dwarfs other contributors.
Palmer cites a meta‑analysis of over 3 million people: women with obesity have double the risk of having an autistic child; women with diabetes, double; having both quadruples the risk. Men with obesity also have double the risk. He frames this in the mitochondrial lens: parental mitochondrial dysfunction prior to conception impairs gamete quality and in utero neurodevelopment. The rising prevalence of metabolic syndrome (high triglycerides, low HDL, hypertension, abdominal obesity, elevated glucose) directly parallels the rise in neurodevelopmental disorders, yet public health discourse rarely connects them.
When you put the two together, obese and diabetic, quadruple the rate of autism in the offspring.
Also said
“Only 7% of Americans are healthy in all five biomarkers of metabolic syndrome.”— Quantifies the scale of the metabolic health crisis that Palmer ties directly to mental health.

Brain Energy by Dr. Chris Palmer
Book
Palmer’s book presents the mitochondrial theory of mental illness in detail, integrating decades of research and clinical insights. Huberman highly recommends it at the end of the episode.
Throughout the conversation, Palmer refers to the material covered in his book ‘Brain Energy,’ which outlines how mental disorders are metabolic disorders of the brain. Huberman calls it ‘absolutely spectacular’ and encourages listeners to read it for a deeper understanding of the mechanisms and treatment protocols. The book provides the evidence base for the clinical approaches Palmer is pioneering.
If you're learning from and or enjoying this podcast… to learn more about Dr. Palmer's work… and his absolutely spectacular book Brain Energy, please see the show note captions.
Palmer cites Valter Longo’s ProLon, a 5‑day 600‑calorie plant‑based ketogenic diet, as one option for periodic metabolic reset, noting that proceeds fund research. He states you can get similar benefits by simply not eating or by eating 600 calories of whole foods.
ProLon is a packaged meal program designed to mimic fasting while providing micronutrients. Palmer mentions Longo’s series of published studies showing improvements in metabolic and longevity biomarkers after doing the 5‑day cycle a few times per year. While not endorsing the specific product over homemade versions, he presents it as a validated tool within the intermittent fasting/ketogenic domain. He emphasizes the underlying biology rather than the product per se.
vs alternatives
Compared to DIY water‑only fasting or strict keto, ProLon offers convenience and some evidence base, but Palmer notes you can achieve similar results with 600 kcal/day of any appropriate foods.
He has a proprietary product called ProLon. You can get the benefits by just not eating anything or by eating 600 calories a day. You don't need to buy that proprietary product.
Huberman mentions AG1 as an all-in-one vitamin, mineral, probiotic drink with adaptogens that covers foundational nutritional needs and supports gut health, immune function, and mood. He has taken it since 2012.
DisclosureSponsor of the Huberman Lab podcast; Huberman personally uses it daily.
Huberman describes AG1 as providing all necessary vitamins, minerals, and micronutrients along with probiotics and prebiotics to support a healthy gut microbiome. He says it is the one supplement he would take if he could only take one, noting improvements in digestion, immune robustness, and mental focus. This aligns with Palmer’s emphasis on nutritional foundation and gut-brain metabolic connections.
Personal experience
Huberman shares: 'I've been taking AG1 daily since 2012 … when I take AG1 daily, my digestion is improved, my immune system is more robust, and my mood and mental focus are at their best.'
If I could take Just One supplement, that supplement would be ag1.
Element provides sodium, magnesium, and potassium in correct ratios without sugar; Huberman uses it every morning and during exercise to maintain hydration and electrolyte balance.
DisclosureSponsor of the Huberman Lab podcast; Huberman personally uses it.
Huberman explains that even slight dehydration impairs cognitive and physical performance, and that electrolytes are critical for neuronal function. He dissolves one packet in 16–32 oz water first thing in the morning and during exercise, especially when sweating. In Palmer's framework, proper hydration and electrolyte balance directly support mitochondrial membrane potentials and ATP synthesis.
Personal experience
Huberman: 'I dissolve one packet of element in about 16 to 32 ounces of water when I wake up in the morning and I drink that basically first thing in the morning.'
Element is an electrolyte drink that has everything you need but nothing you don't—that means the electrolytes sodium, magnesium, and potassium all in the correct ratios but no sugar.
Eight Sleep is a smart mattress cover with cooling, heating, and sleep tracking that optimizes bed temperature across the night to improve deep and REM sleep.
DisclosureSponsor of the Huberman Lab podcast; Huberman has used Eight Sleep for 4 years.
Huberman underscores that body temperature must drop 1–3° to fall asleep and rise to wake up; Eight Sleep automates this. He has used it for years and says it transformed his sleep quality. The new model has snoring detection that adjusts head elevation. This directly relates to Palmer’s pillar of sleep as essential for mitochondrial repair and brain health.
Personal experience
Huberman: 'I've been sleeping on an Eight Sleep mattress cover for 4 years now and it has completely transformed and improved the quality of my sleep.'
Eight sleep automatically regulates the temperature of your bed throughout the night according to your unique needs.
Our Place makes PFAS-free, titanium non‑stick cookware that does not degrade or release toxic forever chemicals, reducing exposure to hormone disruptors and gut microbiome damage.
DisclosureSponsor of the Huberman Lab podcast; Huberman uses the pan daily.
Huberman highlights that 80% of non‑stick pans still contain PFAS (Teflon) linked to hormone disruption, gut dysbiosis, and fertility issues. The Titanium Always Pan Pro uses pure titanium with zero chemicals and no coating, maintaining non‑stick performance without toxic risks. He cooks eggs, burgers, and steaks in it. In the context of Palmer’s message, avoiding environmental toxins like PFAS reduces mitochondrial toxicant load, complementing dietary interventions.
Personal experience
Huberman: 'I cook eggs in my titanium Always Pan Pro almost every morning … nothing sticks to it; it's really easy to clean.'
The first non-stick pan made with zero chemicals and zero coating—instead it's pure titanium. This means it has no harmful forever chemicals.
Function offers over 100 advanced lab tests (heart, hormones, immune, nutrients, toxins like PFAS/BPA) with expert doctor insights. Huberman discovered elevated mercury and used the results to modify diet and supplement with NAC.
DisclosureSponsor of the Huberman Lab podcast; Huberman is a member and joined their scientific advisory board.
Huberman describes Function as a comprehensive, affordable blood‑testing service that provides actionable health snapshots. After his initial test revealed high mercury, he limited tuna, increased leafy greens, and supplemented NAC to boost glutathione, then confirmed improvement on a second test. This aligns with Palmer’s vision of personalized metabolic assessment—identifying specific nutritional deficits, toxicities, and metabolic dysfunctions before they manifest as mental illness.
vs alternatives
Unlike standard annual physicals that test only a few biomarkers, Function provides extensive metabolic, hormonal, and toxin panels, making it a step toward the comprehensive mitochondrial health metric Palmer advocates.
Personal experience
Huberman: 'In one of my first tests with function I learned that I had elevated levels of mercury in my blood. Function not only helped me detect that but offered insights into how best to reduce my mercury levels.'
Function provides over 100 Advanced lab tests that give you a key snapshot of your entire bodily health.
