Introduction

In this section, Andrew Huberman introduces the podcast and his guest, Dr. Chris Palmer.

Introducing the Podcast and Guest

Andrew Huberman welcomes listeners to the Huberman Lab podcast.

Dr. Chris Palmer is introduced as a medical doctor specializing in psychiatry at Harvard Medical School.

Dr. Palmer's expertise lies in understanding the relationship between metabolic disorders and psychiatric disorders.

Dr. Chris Palmer's Expertise

In this section, Andrew Huberman describes Dr. Chris Palmer's expertise in treating various psychiatric disorders using different forms of nutrition.

Treating Psychiatric Disorders with Nutrition

Dr. Palmer treats a variety of conditions including schizophrenia, ADHD, OCD, anxiety disorders, and depression among others.

He understands how metabolism and these various disorders of the mind interact.

He shares remarkable case studies of individuals and groups who have achieved tremendous relief from psychiatric disorders through diet interventions.

He raises the hypothesis that perhaps obesity is a consequence of brain dysfunction rather than metabolic dysfunction that impacts the brain.

The Role of Mitochondrial Function in Mental Health

In this section, Dr. Chris Palmer discusses his hypotheses about mitochondrial function and dysfunction play in mental health and mental illness.

Mitochondrial Function and Mental Health

Mitochondrial function plays critical roles in mental health and mental illness.

Various types of diets ranging from ketogenic to modified ketogenic diets can be used to change mitochondrial function for relief from various psychiatric illnesses.

These diets were not first developed for weight loss but rather as treatments for neurological conditions such as epilepsy.

The Impact of Food on Brain Function

In this section, Dr. Chris Palmer explains how food alone or in combination with fasting can interact with the way our brain functions.

Food and Brain Function

The foods we eat alone or in combination, and how fasting can interact with the way our brain functions.

These interactions strongly control the way we think, feel, and behave.

Dr. Palmer points to various actionable measures that people can take in order to improve their mental health.

Dr. Chris Palmer's Book

In this section, Andrew Huberman mentions Dr. Chris Palmer's book "Brain Energy: A Revolutionary Breakthrough in Understanding Mental Health and Improving Treatment for Anxiety, Depression, OCD, PTSD and More."

About the Book

The book is titled "Brain Energy: A Revolutionary Breakthrough in Understanding Mental Health and Improving Treatment for Anxiety, Depression, OCD, PTSD and More."

It provides a much-evolved understanding of how psychiatric disorders emerge in people.

It revises understanding about possible origins of various psychiatric disorders and best ways to treat them including both medications but also nutritional approaches.

Conclusion

In this section, Andrew Huberman concludes the podcast by thanking sponsors and emphasizing his desire to bring zero cost-to-consumer information about science-related tools for the general public.

Eight Sleep Mattress Covers

In this section, Andrew Huberman discusses the importance of body temperature in sleep and introduces Eight Sleep's smart mattress covers that can adjust the temperature of your sleeping environment.

Importance of Body Temperature in Sleep

Our body temperature needs to drop by about 1 to 3 degrees in order to fall asleep and stay deeply asleep throughout the night.

Conversely, when we wake up in the morning, it is because our body heats up by 1 to 3 degrees.

Different people have different core body temperatures that tend to run colder or hotter throughout the night.

Eight Sleep Mattress Covers

Eight Sleep makes smart mattress covers with cooling, heating, and sleep tracking capacity.

The mattress cover allows you to adjust the temperature of your sleeping environment so that you have the optimal temperature for a good night's sleep.

Andrew Huberman has been using an Eight Sleep mattress cover for eight months and it has completely transformed his sleep.

Nutrition's Impact on Mental Health

In this section, Andrew Huberman introduces Dr. Chris Palmer to discuss how nutrition impacts mental health over long periods of time.

Interaction Between Nutrition and Mental Health

Nutrition interacts with our mental health in an intimate, maybe even causal way over long periods of time.

What we eat yesterday or the day before, maybe even 10 years ago could be impacting the way we feel mentally today.

Most people know what mental illness is or have some idea what it is. Fewer people certainly know how closely nutrition can interact with it.

Short-Term Effects of Food on Mood

When we eat a food that tastes delicious to us or that we associate with something nice, then we feel good mentally and physically.

Conversely, when we eat something that gives us food poisoning or maybe even something that just doesn't taste great or that we associate with a bad experience, we feel less good in the short term.

Introduction

In this section, Chris Palmer shares his personal story and how he discovered the benefits of altering his nutrition to improve his health.

Personal Story

As a child, Chris Palmer had mental illness that started with OCD.

He experienced adverse childhood events and was homeless with his mother for a while.

During his internship and residency at Harvard, he was diagnosed with metabolic syndrome despite being on a low-fat diet and exercising regularly.

His doctor recommended medication for pre-diabetes, cholesterol, and blood pressure.

After trying the Atkins diet, he lost abdominal fat and improved his metabolic syndrome within three months.

Mental Health

Before switching to the new diet, Chris Palmer experienced OCD as a child and was headed towards more severe metabolic syndrome.

Struggling with Medications and Psychotherapy

In this section, Chris Palmer talks about his experience with medications and psychotherapy for depression and OCD. He shares how he was functioning at a high level but still struggling with low-grade symptoms. He also discusses the side effects of medications and how they were not helping him.

Medications and Psychotherapy

Chris tried different medications to feel better, but they came with more side effects than benefits.

He had been in psychotherapy on and off for years, but it was essentially worthless for him.

Chris was hospitalized at one point and put on lithium and imipramine, which did nothing beneficial for him.

After doing a diet for three months, Chris noticed dramatic improvement in his mood, energy, concentration, and sleep.

Feeling Good after Diet Change

In this section, Chris Palmer talks about the positive changes he experienced after changing his diet. He shares how he felt so good that he started waking up before his alarm went off feeling rested.

Positive Changes after Diet Change

The thing that was most striking to Chris after doing the diet for three months was the dramatic improvement in his mood, energy, concentration, and sleep.

His goal was to get rid of metabolic syndrome which he achieved seemingly miraculously by getting rid of everything with one dietary change.

For the first time in his life, Chris started waking up before his alarm went off feeling rested.

Understanding "Haves" vs "Have-Nots"

In this section, Chris Palmer talks about his previous understanding of "haves" and "have-nots." He shares how he always felt like there were two types of people in the world and how he never understood who had energy to go and play hard.

Understanding "Haves" vs "Have-Nots"

Chris always felt like there were two types of people in the world: happy, peppy people who just are so positive and have energy, and those who don't.

He assumed that they were just part of the "haves" in the world, lucky and privileged.

After changing his diet, Chris felt so good that he realized he was now one of those happy, peppy people with energy.

The Journey to Nutrition and Mental Health

In this section, Chris Palmer talks about how he discovered the connection between nutrition and mental health. He also shares his experience with friends and family who tried the diet.

Discovery of Nutrition's Role in Mental Health

What we see is not always what's going on internally with people.

There are more people suffering than we realize.

Tools are needed to overcome that suffering.

Nutrition can play a profound role in how you feel and operate.

Early Experiments with Diet

Friends and family saw that Chris had improved his health.

They noticed dramatic improvement in their moods, energy, sleep, and everything else.

The primary thing Chris noticed was a powerful antidepressant effect.

Chris got some of his patients to try it, and some ended up having a remarkable and powerful antidepressant effect.

Clinical Trials of Atkins Diet

At that point (before 2016), there weren't many clinical trials of the safety or efficacy of the Atkins diet for even weight loss or diabetes, let alone any mental disorders.

Chris felt like he was on the fringe here.

He offered it to patients but laid low until 2016.

Questions About the Diet

Andrew Huberman asks about the diet.

Prescribing a Nutrition Plan for Patients

Chris Palmer discusses how he prescribed nutrition plans for his patients and the observations he made regarding adherence to the plan.

Prescribing a Ketogenic Diet

Early on, Chris was winging it and recommending an Atkins diet to achieve urinary ketosis.

He strongly recommended that patients achieve urinary ketosis as he noticed that clinical benefits were observed once they got into ketosis.

Fasting can limit carbohydrate intake and get patients into ketosis. Some of his patients did intermittent fasting or ate primarily fats to get into a state of ketosis.

Overweight and obese patients found it easier to get into ketosis by limiting carbohydrates.

Observations on Adherence

Chris used urine strips to monitor ketones since blood monitors were not available at the time.

Patients who tried the diet but did not get ketones often did not experience clinical benefits.

As years went by, more research was coming out, and people were getting more sophisticated with blood ketone monitoring and different versions of ketogenic diets.

Helping a Patient with Schizoaffective Disorder Lose Weight

Chris Palmer shares how he helped a patient with schizoaffective disorder lose weight.

Understanding Schizoaffective Disorder

Schizoaffective disorder is essentially schizophrenia with superimposed mood episodes.

Helping a Patient Lose Weight

The patient had been seeing Chris for eight years when they decided to try losing weight in 2016.

Understanding Schizophrenia and the Ketogenic Diet

In this section, Chris Palmer and Andrew Huberman discuss schizophrenia and the challenges of treating it with medication. They also share a case study of a man with schizoaffective disorder who experienced significant improvements in his symptoms after adopting a ketogenic diet.

Schizophrenia Medication Challenges

Patients with schizophrenia often struggle to find effective medications that don't cause severe side effects.

Traditional antipsychotic medications for schizophrenia can cause weight gain, prolactin increases, breast development, movement disorders, and other negative side effects.

Abruptly stopping antipsychotic medication can lead to rebound psychosis or aggression.

Case Study: Ketogenic Diet for Schizoaffective Disorder

A man with schizoaffective disorder asked for help losing weight to improve his self-esteem.

After two weeks on a ketogenic diet, he began experiencing an antidepressant effect and improved social interactions.

Six to eight weeks into the diet, he reported that his auditory hallucinations were going away and that he no longer believed in paranoid delusions about powerful families controlling his thoughts.

The man lost 160 pounds and was able to complete a certificate program, perform improv in front of an audience, and go out in public without paranoia.

Athletic Greens Sponsorship

In this section, the speaker talks about Athletic Greens, a vitamin mineral probiotic drink that covers all of your foundational nutritional needs. He explains why he started taking it and how it helps with gut health.

Benefits of Athletic Greens

The probiotics in Athletic Greens are optimal and vital for microbiotic health.

It contains a number of adaptogens, vitamins, and minerals that make sure that all of my foundational nutritional needs are met.

It tastes great.

Medication and Adherence

In this section, the speaker discusses medication and adherence when it comes to treating mental health disorders like schizoaffective disorder.

Medication Use

The patient has remained on medication throughout his treatment.

Attempts have been made to taper him off his meds over the years but it has not been easy due to his long-term use.

Importance of Supervision When Reducing Medications

Getting off psychiatric medications is very difficult and dangerous.

This is true for any psychiatric medication including depression medication.

Patients need supervision from a mental health professional or a prescriber when reducing their medication.

Adherence to Diet

The speaker discusses the challenges of adhering to a ketogenic diet for someone with schizoaffective disorder.

He also talks about how difficult it can be for anyone to adhere to a ketogenic diet, especially in its extreme form at first.

The Importance of Frequent Contact and Biomarkers in Clinical Work

In this section, Chris Palmer and Andrew Huberman discuss the importance of frequent contact and biomarkers in clinical work.

Monitoring Compliance

Psychiatrists often prescribe medication without frequent follow-up appointments.

Early on, Palmer's patient was adherent to the ketogenic diet, allowing for weekly check-ins.

Blood ketone monitors provide an objective biomarker of compliance or noncompliance with the ketogenic diet.

Medication Compliance vs. Dietary Compliance

Patients are often noncompliant with prescription medications due to forgetfulness or changes in routine.

Most patients prescribed drugs for psychiatric conditions are not giving blood every time they talk to their psychiatrist or psychologist.

Measuring Ketones as a Key Variable

In this section, Palmer and Huberman discuss measuring ketones as a key variable in the ketogenic diet.

Staying in Ketosis

The presence of ketones is a key variable in being "in ketosis."

To stay in ketosis, blood levels of ketones must be monitored.

Patient-Specific Treatment Plans

Not every patient needs the ketogenic diet; some may benefit from simply eliminating junk food from their diets.

Insulin Resistance and Mental Health

In this section, Palmer discusses emerging data that suggests insulin resistance is linked to chronic mental disorders.

Link Between Diet and Mental Health

Highly processed foods that are high in sugar, carbohydrate, and fats seem to be the worst foods for metabolic health.

Insulin resistance is impaired in people with chronic mental disorders.

Using Nutrition to Treat Mental Illness

In this section, Dr. Chris Palmer discusses how he uses nutrition to treat mental illness and the importance of a ketogenic diet for certain patients.

Decreasing Glucose and Insulin Levels

For some patients, decreasing glucose and insulin levels can be achieved by eliminating sweets from their diet.

This approach is not effective for patients with schizoaffective disorder, schizophrenia or bipolar disorder.

Patients with these conditions require a ketogenic diet with high levels of blood ketones.

Blood ketone levels greater than 0.8 are recommended for depression while levels greater than 1.5 are recommended for psychotic disorders and bipolar disorder.

Reversing Metabolic Syndrome

Avoiding insulin resistance and reversing metabolic syndrome is the target when using nutrition as a treatment tool for mental illness.

Eliminating highly processed foods and focusing on nonprocessed or minimally processed foods can help some people.

Others may benefit more from a full-blown ketogenic diet.

The Use of Ketogenic Diet in Treating Epilepsy

The use of the ketogenic diet to treat epilepsy dates back in history.

Nutrition as a treatment tool for mental illness is still considered heretical by many people.

Dr. Palmer emphasizes that nutrition needs to be considered one of the major tools in the landscape of effective treatments for mental illness.

Conclusion

Nutrition can be very effective in treating mental illness when used alongside other treatments such as medication.

Dr. Palmer shares stories of miraculous transformations resulting from changes in nutrition.

The use of nutrition as a treatment tool should not be discarded without proper consideration.

The History of the Ketogenic Diet

In this section, Dr. Chris Palmer explains how the ketogenic diet was developed to treat epilepsy and not as a weight loss diet.

The Development of the Ketogenic Diet

The ketogenic diet was developed in 1921 by a physician for one purpose only - to treat epilepsy.

Fasting can stop seizures, but it is not a healthy diet. However, fasting causes shifts in metabolism that are beneficial to human health.

Intermittent fasting was used on a child with seizures and found to be effective. However, fasting cannot be used as a long-term treatment because people will starve to death.

Dr. Russell Wilder at the Mayo Clinic developed the ketogenic diet with one purpose - to mimic the fasting state using this special diet to see if it might stop seizures long-term.

Efficacy of the Ketogenic Diet

Early results were extraordinarily positive with 50% of patients who use the ketogenic diet becoming seizure-free and another 35% having a 50% or greater reduction in their seizure frequency.

About 30% of people with epilepsy do not respond to current treatments available and have treatment-resistant epilepsy. The ketogenic diet works for about 1/3 of these cases where other treatments have failed.

Conclusion

The ketogenic diet was initially developed as a treatment for epilepsy and has been shown to be effective in treating some cases of treatment-resistant epilepsy.

The Benefits of the Ketogenic Diet

In this section, Chris Palmer discusses the benefits of the ketogenic diet and how it affects calcium channel regulation, gene expression, brain inflammation, gut microbiome, insulin resistance, glucose levels and insulin signaling. He also explains how the diet stimulates two processes related to mitochondria: mitophagy and mitochondrial biogenesis.

Benefits of the Ketogenic Diet

Changes calcium channel regulation and calcium levels

Changes gene expression

Reduces brain inflammation

Changes gut microbiome in beneficial ways

Improves insulin resistance

Lowers glucose levels and insulin levels which improves insulin signaling

Mitochondrial Function

Stimulates a process called mitophagy which gets rid of old and defective mitochondria and replaces them with new ones.

Stimulates a process called mitochondrial biogenesis which means that after people have done the ketogenic diet for a while-- months or years-- many of their cells in their bodies and brains will have more mitochondria.

This is believed to be why the ketogenic diet is such a powerful treatment not only for epilepsy but also for people with chronic mental disorders.

Mental Disorders Treated by Ketogenic Diet

In this section, Chris Palmer lists some neurological symptoms and diseases as well as psychiatric disorders that can be treated by nutritional changes including depression, bipolar disorder, schizophrenia, PTSD, Alzheimer's disease among others.

Neurological Symptoms & Diseases

None mentioned

Psychiatric Disorders

Depression

Bipolar Disorder

Schizophrenia

PTSD

Alzheimer's Disease

Nutritional Psychiatry

In this section, Chris Palmer explains that nutritional psychiatry is a broad field and in its infancy. He also mentions that there are no randomized controlled trials documenting efficacy in large numbers of patients with these disorders yet. However, there are case studies and mechanistic science papers outlining the benefits of the ketogenic diet for chronic mental or neurological disorders.

Nutritional Psychiatry

Broad field

No randomized controlled trials documenting efficacy in large numbers of patients with these disorders yet

Case studies and mechanistic science papers outlining the benefits of the ketogenic diet for chronic mental or neurological disorders exist

Using Epilepsy Treatments in Psychiatric Patients

Dr. Palmer discusses the use of epilepsy treatments in psychiatric patients and how the ketogenic diet is an established evidence-based treatment for serious mental disorders.

Epilepsy Drugs Used in Psychiatry

Depakote, Tegretol, Lamictal, Topamax, Neurontin or gabapentin, Valium, Klonopin, Xanax are all medications that stop seizures.

Many of these drugs were developed initially for seizures but are used off-label to treat psychiatric disorders.

Psychiatrists often use epilepsy treatments as a tool to alter brain chemistry when FDA-approved treatments are not effective.

The Tools of Psychiatry

Dr. Huberman and Dr. Palmer discuss the tools used by psychiatrists to diagnose and treat mental health disorders.

Language and Observing Behavior

Psychiatrists use language and observing behavior as their dissection tools for what's going on in someone's brain.

Altering Brain Chemistry

Neuroscientists have tools for altering brain chemistry such as antidepressants or antipsychotics that adjust dopamine or serotonin levels.

Adjusting nutrition or eliminating highly processed foods can also be a tool for altering brain chemistry.

The Importance of Nutrition in Mental Health

Dr. Huberman discusses the importance of nutrition in mental health with Dr. Palmer.

Good vs Unclear vs Prescription Drugs Only

A third of people believe that diet, exercise, social connection, limiting stress are good tools for treating mental health disorders.

Another third is unclear about the effectiveness of non-prescription drug treatments.

The final third believes that only prescription drugs have a place in medicine.

Mitophagy and Mitochondrial Biogenesis

Mitochondria are the energy factories of cells and are present everywhere in neurons.

Mitophagy is the process by which damaged mitochondria are removed from cells.

Mitochondrial biogenesis is the process by which new mitochondria are created.

Mitochondria and Mental Health

In this section, Chris Palmer and Andrew Huberman discuss the importance of mitochondria in mental health. They explain that mitochondria are not just little batteries but also play a crucial role in directing and allocating resources throughout a cell. They also discuss how mitochondria are involved in the production, release, and regulation of key neurotransmitters.

Mitochondrial Biology

Mitochondria are not just little batteries but also direct and allocate resources throughout a cell.

Mitochondria play a direct role in the production, release, and regulation of key neurotransmitters such as serotonin, dopamine, glutamate, acetylcholine.

Mitochondria provide energy for the production of neurotransmitters.

Mitochondria are directly related to the levels of reactive oxygen species in a cell which plays a role in epigenetic expression.

Importance of Mitochondrial Research

The field of mitochondrial research is one of the most cutting-edge fields in medicine right now.

Any excess or deficiency in neurotransmitters can have profound negative effects on the nervous system.

One study found that mitochondria are responsible for the expression of about 60% of genes in a cell.

Other Functions of Mitochondria

Fascinatingly, mitochondria move along the membrane of synapses to release batches of vesicles containing neurotransmitters.

Mitochondria manage calcium regulation in cells which plays a role in epigenetic expression.

Mitochondrial at least play a role in all aspects of the human stress response.

Mitochondria and Mental Health

In this section, the speaker discusses the role of mitochondria in mental health and how they impact various stress responses, cortisol production, inflammation, neurotransmitters, hormones, and epigenetic expression.

Mitochondrial Impact on Stress Response

Genetically modified mitochondria were found to impact all four buckets of stress response.

This implies that mitochondria play a role in stress response.

Mitochondrial Role in Cortisol Production

Mitochondria have the enzyme required for the synthesis of steroid hormones including cortisol.

Dysfunctional or short supply of mitochondria may lead to dysregulated production of these hormones.

Mitochondrial Direct Role in Inflammation

Mitochondria turn on and off the inflammatory system by regulating certain inflammatory cells.

Reactive oxygen species levels are key signaling processes to turn off inflammatory cell process.

Mitochondrial Role in Wound Healing

Macrophages play an important role in wound healing.

The state of macrophages is induced by mitochondrial signals that change with different phases of wound healing.

Connecting Mental Illness Puzzle with Science of Mitochondria

Neurotransmitters, hormones, epigenetic expression, and inflammation are key variables disrupted in people with mental disorders.

Understanding the science of mitochondria can connect all these dots.

InsideTracker Sponsorship Message

Mitochondria: Lumpers vs Splitters

In this section, the speaker talks about how scientists are divided into lumpers and splitters when it comes to naming things after themselves.

Lumpers vs Splitters

Scientists are often divided into lumpers and splitters.

Lumpers make things simple while splitters subdivide into a ton of detail.

Scientists tend to be splitters as there is more territory to go around if you're splitting than if you're lumping.

Mitochondria and Mitophagy

In this section, the speakers discuss mitochondria and mitophagy. They explain that mitochondria are responsible for many sophisticated functions within cells, not just energy production. They also introduce the concept of autophagy and how it relates to mitophagy.

Mitochondrial Function

Mitochondria are responsible for many sophisticated functions within cells beyond energy production.

Autophagy is the gobbling up of one's own dead or injured cells in a carefully orchestrated way.

Mitochondrial dysfunction has long been associated with everything that ails us essentially.

Autophagy and Fasting

Autophagy is stimulated by fasting states or fasting-mimicking states.

Fasting and calorie restriction have been shown to induce longevity by stimulating the body to become lean and conservative in terms of its allocation of resources.

Mitophagy

Mitophagy is the intentional or unintentional gobbling up of mitochondria, presumably to replace them with newer healthier mitochondria.

Different mitochondria even within the same cell may very well be specializing in different tasks.

There do appear to be some unique regulators of mitophagy compared to autophagy more broadly.

Mitochondrial Theory of Aging

In this section, the speaker discusses the mitochondrial theory of aging and how it has evolved over time.

Reactive Oxygen Species and Mitochondria

Reactive oxygen species (ROS) were once thought to be the primary cause of aging according to the mitochondrial theory of aging in the 1970s.

ROS are not all bad as they serve a signaling process and are a normal part of human functioning and cellular function.

High levels of ROS are still bad for you, but our understanding of mitochondria's role in producing ROS has expanded.

Mitophagy

Defective mitochondrial function is possibly the unifying cause of aging and all related disorders.

Mitophagy is a process that tries to address defective mitochondria by getting rid of old or defective ones and replacing them with new ones.

Calorie restriction is one way to stimulate mitophagy, which is an effective tool for preventing aging in various animal species.

Glucose Levels in the Brain

In this section, the speaker discusses glucose levels in the brain and their relationship with fasting, ketogenesis, insulin management, mental health, physical health, and neuron tuning.

Neurons Love Glucose?

Neurons love glucose because they live on it. However, when there's too much glucose around, they become sick.

Fasting can make animals less faithful representatives of what's out there in the world. Yet intermittent fasting can improve mental clarity more than having a big bowl of pasta probably due to other reasons related to serotonin and tryptophan.

Low Blood Glucose in The Brain?

Various diets including ketogenic diet, fasting, and reducing sugar intake can assist in mitochondrial function and mitophagy.

The common theme here is that glucose levels in the brain need to be reduced. For some people, removing sweets and refined sugars brings down their blood glucose level substantially.

It seems like the common pathway of all those things (fasting, ketogenesis) is that glucose levels in the brain need to be reduced.

The Role of Mitochondria in Mental and Physical Health

In this section, Chris Palmer and Andrew Huberman discuss the role of mitochondria in mental and physical health, as well as the impact of diet on glucose regulation.

Mitochondrial Dysfunction and Glucose Regulation

Chris Palmer suggests that glucose may be a symptom rather than the real story when it comes to neurons' love for glucose.

Recent studies have shown that astrocytes in the hypothalamus play a key role in glucose regulation throughout the body, implying that mitochondria in those astrocytes are probably playing a key role.

High glucose levels can be a symptom of metabolic dysfunction somewhere in the body or brain. Mitochondrial dysfunction is likely to be the root cause of dysregulation of glucose levels.

Impact of Diet on Glucose Regulation

Consuming massive amounts of junk food, sugar, and other things can lead to dysregulation of glucose levels.

People who eat moderate amounts of carbohydrates may still experience dysregulation of glucose levels. However, there is no clear-cut answer as to whether they would feel better if they were in a lower glucose state.

The ketogenic diet is an effective treatment for some people but does not necessarily imply that eating carbohydrates was the root cause of their problem.

Conclusion

Chris Palmer distinguishes between cause (the actual root cause) and effective treatments. He believes that mitochondrial dysfunction is often the root cause but acknowledges that many people disagree with him on this point.

Ketogenic Diet and Obesity

In this section, Chris Palmer discusses the effectiveness of the ketogenic diet as an intervention for infants with epilepsy. He also talks about the broader topic of obesity and how dietary intervention can change brain metabolism and improve symptoms in adults.

Ketogenic Diet for Infants with Epilepsy

The ketogenic diet is an effective intervention for infants with uncontrollable seizures.

Breast milk is the optimal food source for infants, but some still experience seizures despite consuming it.

Putting infants on a ketogenic diet can stop seizures even if their cause was not a bad diet.

Broader Topic of Obesity

The cause of obesity is unknown according to a conference held by the Royal College of Obesity Medicine.

Some argue that excess caloric intake beyond one's daily metabolic needs causes obesity, but this does not explain why there is an epidemic of obesity.

Environmental factors such as food, toxins, stress levels, poor sleep, and lack of sunlight are known to impair mitochondrial function which may be key to the obesity epidemic.

Impaired mitochondrial function in parts of the brain that regulate metabolism and eating behaviors may lead to overeating or inability to metabolize large amounts of food.

Personal Anecdotes

Despite growing up on junk food like Kool-Aid and Twinkies in the 70s, Chris Palmer did not become obese.

Andrew Huberman notes that compared to when he was growing up, there are fewer individuals who can eat anything without gaining weight.

Inheritance of DNA

The discussion is about the inheritance of DNA and whether mitochondrial DNA comes exclusively through the maternal side.

Maternal DNA and Mitochondrial DNA

We inherit genes from both parents, but there are regions in our brain that carry neurons purely of mom's or dad's DNA.

Mitochondrial DNA does not come exclusively through the maternal side.

You inherit mitochondria and 36 genes from your mother, but most proteins that make up mitochondria are encoded in nuclear DNA inherited from both parents.

Mitochondrial Dysfunction

Mitochondrial dysfunction is a primary driver of mental illness and metabolic illness.

People who have mitochondrial defects or rare mitochondrial diseases could inherit them from either parent because it can be a defect in the nuclear genes that code for proteins that make up mitochondria.

Sleep disruption, high levels of stress and trauma, drug and alcohol use impair mitochondrial function.

THC and Mitochondria

THC directly impairs mitochondrial function by binding to CB1 receptors on mitochondria.

Adolescents who use a lot of marijuana have areas of their brains with a greater number of CB1 receptors that are atrophied compared to normal healthy controls.

CB1 receptors on mitochondria play a role in memory impairment induced by THC as well as lack of motivation.

Alcohol and THC

In this section, Andrew Huberman and Chris Palmer discuss the effects of alcohol and THC on the brain. They also talk about a study that was conducted to see if a ketogenic diet could help with alcoholism.

Alcohol's Effect on the Brain

Drinking no alcohol is healthier than drinking any amount of alcohol.

High concentrations of THC in products can be problematic, especially for adolescents who are predisposed to brain atrophy and psychosis.

Alcohol disrupts the way that the brain uses fuels, which may make it seem more rewarding to those who drink it.

Chronic alcoholics have a chronic deprivation of energy in reward pathway cells due to metabolic compromise.

Ketogenic Diet for Alcoholism

A study led by Nora Volkow showed that a ketogenic diet improved brain metabolism in key areas for patients with alcohol use disorder.

Patients who received a ketogenic diet required fewer benzodiazepines for their detox, had fewer withdrawal symptoms from alcohol, reported fewer cravings for alcohol, and showed reduced levels of neuroinflammation.

Brain Metabolic Defects and Alcoholism

In this section, Chris Palmer discusses the potential for correcting brain metabolic defects caused by chronic alcohol use to help people overcome alcoholism. He also highlights a cautionary note about the effects of alcohol on individuals following a ketogenic diet.

Brain Metabolic Defects and Alcoholism

Correcting brain metabolic defects from chronic alcohol use may help people overcome alcoholism.

Researchers found that rats on a ketogenic diet had a five-fold increase in blood alcohol levels when exposed to the same amount of alcohol as rats on a standard diet.

Individuals following a ketogenic diet should not drink the same amount of alcohol as they normally would because their blood alcohol levels may be significantly higher than usual.

Drinking on an empty stomach can have similar effects to drinking while on a ketogenic diet.

The Role of Astrocytes in Brain Function

In this section, Andrew Huberman and Chris Palmer discuss astrocytes, non-neuron cells in the brain that are important for regulating various functions such as metabolism and disease prevention.

The Role of Astrocytes in Brain Function

Astrocytes are non-neuron cells in the brain that play an important role in regulating various functions such as metabolism and disease prevention.

The hypothalamus is responsible for regulating basal functions like metabolism, which is why it is often implicated in studies related to organ health, obesity, etc.

Effects of Ketogenic Diet on Brain

In this section, the speakers discuss the effects of a ketogenic or low blood glucose diet on the brain. They also talk about neuroimaging studies that have been conducted to measure changes in brain function under different dietary conditions.

Neuroimaging Studies

Chris Palmer mentions that there are some neuroimaging studies that have been conducted to measure changes in brain function under different dietary conditions.

PET scans can be used to measure glucose metabolism in the brain. Stephen Cunnane has done research using PET scans to study Alzheimer's disease patients and models.

Patients with Alzheimer's disease often show glucose hypometabolism, which may be attributed to insulin signaling impairment. Some researchers call it type III diabetes.

Cells not getting enough energy from glucose as a fuel source is backed by numerous research studies. There is debate about whether this is a primary driver of Alzheimer's disease.

Ketone Supplements

Stephen Cunnane has done studies where he gives ketone supplements (esters or salts) to patients who are not doing anything special with their diet and notices immediate and direct changes in the metabolism of these metabolically compromised brain cells as measured by PET imaging.

Andrew Huberman shares his personal experience with liquid ketone esters, which he feels greatly increase his energy levels and ability to focus mentally. He eats some carbohydrates each day, usually in proportion to how much high-intensity exercise he does.

Stephen Cunnane has done pilot trials where he simply reduced carbohydrate consumption at breakfast and lunch for nursing home patients who were not put on a ketogenic diet. This resulted in cognitive improvement in a statistically significant way in some of those subjects.

Andrew Huberman highlights the importance of directing carbohydrates to specific portions of the day when one needs to be less focused and alert and yet can replenish glycogen. Limiting carbohydrates most of the time during the day has been a game-changer for him in terms of maintaining alertness, etc.

Ketones and Mood Disorders

In this section, Andrew Huberman and Chris Palmer discuss the potential benefits of supplementing with liquid ketones for people with mood disorders who are not able to adhere to a ketogenic diet.

Liquid Ketones vs. Ketogenic Diet

Supplementing with liquid ketones or prescribing them to people with mood disorders could be beneficial even if they are not willing or able to adhere to a ketogenic diet.

There is no good trial data available yet on whether liquid ketones work as well as a ketogenic diet for controlling mood disorders.

Children and adolescents following a strict ketogenic diet for epilepsy have not been able to control their seizures using exogenous ketones alone without also doing the ketogenic diet.

Multifaceted Benefits of Ketogenic Diet

The benefits of the ketogenic diet go beyond just increasing ketone levels in the body.

A ketogenic diet improves insulin signaling, lowers glucose levels, ramps up mitochondrial biogenesis, and changes gut microbiome and hormone levels.

Drinking ketones alone won't be enough because it doesn't address other issues like high glucose levels from unhealthy food intake.

Potential Uses of Exogenous Ketones

For metabolically healthy individuals, exogenous ketones can play a beneficial role.

Exogenous ketones may be useful for patients who cannot follow a strict ketogenic diet but can do a low carb one.

Exogenous ketones could potentially help alcoholics by drinking them instead of alcohol when experiencing severe cravings.

The Role of Ketones in Brain Fuel

In this section, Chris Palmer discusses the role of ketones and glucose in brain fuel.

Ketones vs Glucose

Some research suggests that there are brain areas or cells that require glucose and cannot use ketones.

There are some areas that require glucose, which is why we have gluconeogenesis to keep the body going and keep the brain going no matter what.

When ketones are available, especially if ketones are high, healthy cells with appropriate abundant mitochondria will continue to use glucose as a fuel source but will also use ketones. However, metabolically compromised tissues such as Alzheimer's disease brains will preferentially use ketones over glucose.

Metabolically Compromised Cells

Metabolically compromised cells send out a distress signal and call resources from the body for energy. If it can't use glucose effectively, it will start using up those ketones instead. This process is critical because if that cell was barely getting by on 60% of its real ATP requirement, it means that it doesn't have enough energy for maintenance and repair functions. As soon as you give that cell a hundred percent energy or close to it, even if you get it up to 90% of its preferred energy amount, it can start to repair itself.

If a cell senses defective molecules or proteins in itself that need replacement once it gets enough fuel (ketone), it will start repairing itself and doing that work.

The Role of Ketogenic Diet in Alzheimer's Disease

In this section, Andrew Huberman talks about how ketogenic diets can help offset some of the symptoms of Alzheimer's and age-related cognitive decline.

Ketogenic Diet for Alzheimer's

The ketogenic diet can be effective in helping to offset some of the symptoms of Alzheimer's and age-related cognitive decline.

There are very few, if any, controlled clinical trials exploring the role of the ketogenic diet for the treatment or reversal of Alzheimer's and age-related cognitive decline.

Many people are terrified of losing their memory due to Alzheimer's or other forms of dementia.

Introduction to Ketogenic Diet and Alzheimer's Disease

In this section, Chris Palmer discusses the results of small pilot clinical trials that have been conducted on the effects of a ketogenic diet on Alzheimer's disease. He also talks about some of the challenges associated with conducting larger studies.

Clinical Trials

A randomized controlled trial found that when patients were in ketosis, they had statistically significant improvement in activities of daily living and quality of life.

Several animal models showed that the ketogenic diet can improve biomarkers of Alzheimer's disease in Alzheimer's models.

Small pilot trials of ketogenic diet in humans showed that it improves biomarkers compared to low fat or American Heart Association diets.

Challenges

Johns Hopkins' researchers attempted to conduct a study comparing Alzheimer's patients' ketogenic diet versus a controlled diet but only 14 out of 27 people completed the study.

Study sections evaluate grants for funding and only about 10% are funded due to limited federal budget for research.

Discussion on Pharmaceutical Companies and Ketogenic Diet

In this section, Andrew Huberman and Chris Palmer discuss whether pharmaceutical companies are suppressing trials on ketogenic diets for Alzheimer's disease.

Pharmaceutical Companies

There is no active suppression by pharma as they would want to capitalize on positive results from studies.

Studies are done by scientists but treatments are generally doled out by pharmaceutical companies and/or physicians.

Conclusion

In this section, Andrew Huberman and Chris Palmer discuss whether there is something special about Alzheimer's patients and people with age-related cognitive decline.

Alzheimer's patients and people with age-related cognitive decline are very dependent on others to cook for them and shop for them.

Intensive Support and Education for Dietary Intervention

In this section, the speaker discusses the importance of intensive support and education for dietary interventions.

Importance of Intensive Support

The speaker emphasizes that a dietary intervention is not like prescribing a pill, as it requires more intensive support and education.

The support could be provided by a health and wellness coach, dietician, or family education.

Providing patients with ketogenic meals can make the diet easier to follow.

Patients who go off the diet experience devastating symptoms which reinforce their adherence to the diet.

Potential Benefits of Dietary Intervention

Patients with Alzheimer's disease may benefit from dietary intervention as it could help them remember better and function better in daily activities.

Going off the diet may cause patients to revert into a more symptomatic state which reinforces their adherence to the diet.

Bias Based on Observation

The speaker believes that based on all the science of metabolism, mitochondria, glucose hypometabolism, etc., dietary intervention has real potential as an effective treatment.

Not everything has to be a randomized clinical trial; there is so much information in medical textbooks.

The Ketogenic Diet for Weight Loss and Epilepsy

In this section, the speakers discuss the ketogenic diet and its effects on weight loss and epilepsy. They also touch on different variations of the diet.

The Ketogenic Diet for Weight Loss

The ketogenic diet is an interesting aspect of weight loss, as is intermittent fasting.

However, the effects of the ketogenic diet on weight loss can be a decoy for most people.

For some people, it can actually bring them underweight.

Different Dosage Ranges of a Nutritional Plan

A physician can prescribe different dosage ranges of a nutritional plan or diet depending on the patient and other factors.

Classic keto involves eating zero carbohydrates or 100 grams or 50 grams, but it depends on the patient and other factors.

There are various versions of keto such as fasting, Atkins, carnivore, vegetarian and vegan versions.

Probing with Initial Dietary Intervention

The first thing to assess with a patient is their symptoms, current diet and what they are willing to do.

There is no one-size-fits-all recommendation for any person when it comes to dietary intervention.

The first variable to look at when recommending or prescribing a ketogenic diet is the person's current weight.

Ketogenic Diet for Brain Health

For obese patients who want to try a ketogenic diet for brain health anyway, carbohydrate restriction usually suffices as an intervention.

Fructose should be avoided, but natural sweeteners like stevia or monk fruit can be used.

The Ketogenic Diet

In this section, Dr. Chris Palmer discusses the ketogenic diet and how it can be used for different types of patients.

Carb Restriction for Obese Patients

For obese patients, Dr. Palmer recommends a carb-restricted diet with less than 20 grams of carbs per day.

They can have all the protein they want, vegetables, and all the fat they want.

Dr. Palmer does not push fat on these people but encourages healthy fats like olive oil, avocados, nuts which are usually considered healthy sources of fat.

Coconut oil or coconut cream is controversial as some organizations consider it unhealthy fat but Dr. Palmer disagrees.

High Fat Diet for Thin Patients

For thin patients who need to be in clinical ketosis, Dr. Palmer recommends a high-fat diet with avocados, olive oil, butter and heavy cream.

Heavy cream is a delicious way to get fats in and can be whipped up into shakes or ice cream.

The beauty of this diet is that there are objective biomarkers such as measuring ketones to adjust the diet based on their state of ketosis and/or clinical benefits.

Protocol for Burned Out Individuals

For individuals who are burned out and exhausted but not under psychiatric care or taking prescription medicines, Dr. Palmer recommends carb restriction initially to see if it produces clinical benefit.

One individual who read his book was able to manage chronic anxiety by following his protocol without medication.

The Importance of Medical Supervision for the Ketogenic Diet

In this section, Dr. Chris Palmer emphasizes the importance of medical supervision for people with serious mental disorders who are considering the ketogenic diet.

Medical Supervision is Crucial for Serious Mental Disorders

For people with serious mental disorders, it's important to work with a medical professional because medications may need to be adjusted.

People with serious mental disorders should treat the ketogenic diet like they have epilepsy because they have a serious brain disorder that impairs their ability to function in the world and affects their health and happiness.

Dieticians can monitor ketosis levels, look for vitamin and nutrient deficiencies, tweak the diet if needed, and provide ideas for meals.

Intermittent fasting or even a three or four-day water fast can be prescribed in conjunction with the ketogenic diet to help regulate blood sugar levels.

Risks Associated With Fasting

Fasting can have its own rewarding properties that aren't just related to weight loss but can also be pathologic in psychiatric patients or those with anorexia nervosa.

There is an important risk associated with fasting that hasn't been mentioned yet. At least in psychiatric patients but even in some patients who use the keto diet for weight loss.

Understanding Mania and Hypomania

In this section, the speakers discuss the differences between mania and hypomania. They also talk about how hypomania can be beneficial for some people.

Mania vs. Hypomania

Mania is problematic and causes problems in some way or another.

Hypomania is something every human being probably craves as it makes one feel extraordinarily good.

Famous people through the ages who have been bipolar were probably most productive during hypomanic episodes.

Coping with Hypomanic Episodes

Getting sufficient quality sleep is important to cope with hypomanic episodes.

Inositol, magnesium, and hot baths can help improve sleep quality.

Adjusting when to eat carbohydrates could be advantageous to make sure that one feels alert and great during the day.

The Dangers of Sleep Deprivation

In this section, the speakers discuss a case of a mental health professional who went six months with two to four hours of sleep every night due to being on a ketogenic diet. They also talk about the dangers of sleep deprivation.

Case Study: Mental Health Professional on Ketogenic Diet

A mental health professional went six months with two to four hours of sleep every night due to being on a ketogenic diet.

Going off the ketogenic diet entirely may be the best idea for someone who is hypomanic.

Adjusting when they eat their carbohydrates would be advantageous in order to make sure that they felt alert and great during the day.

The Dangers of Sleep Deprivation

Sleep deprivation is not healthy, even if one can do it and feel great.

The brain and body suffer from sleep deprivation, and friends and family are also affected.

Education is the first intervention for someone who is not a patient but is using the ketogenic diet.

Strategies for Managing Hypomania

In this section, Dr. Chris Palmer discusses strategies for managing hypomania, including the use of supplements and prescription medications.

Sleep and Hypomania

Falling back to sleep after waking up can take an hour.

Getting three nights of decent sleep in a row can extinguish hypomania.

Supplements like melatonin and magnesium can help with sleep.

Eating carbohydrates before bed can also help calm the body down.

Prescription Medications for Sleep

In this section, Dr. Palmer discusses the use of prescription medications as a temporary stopgap to break the hypomanic cycle.

Prescription Medications

If over-the-counter supplements don't work, prescription sleeping medication may be necessary.

Benzodiazepines or Z medicines like zolpidem or Ambien are commonly used.

Short-term use is recommended (3 to 7 days).

Endocrine System Interactions with Ketosis

In this section, Dr. Palmer discusses interactions between ketosis and the endocrine system.

Hormones and Menstrual Cycles

The impact of low carbohydrate or full ketogenic diets on menstrual cycles is not well understood.

There is no one-size-fits-all answer to how these diets interact with hormones.

Many couples who try the ketogenic diet together find that men have an easier time than women.

Male Fertility

Sub-maintenance caloric diets may improve testosterone-to-estrogen ratios in obese males but could impair testosterone levels in non-obese males.

The Effect of Ketogenic Diet on Female Fertility

In this section, the speakers discuss the effect of a ketogenic diet on female fertility.

Female Mice and Pregnancy

Female mice never got pregnant on the ketogenic diet.

Women who are trying to reproduce should not be fasting.

Women's bodies may actually have significant changes in hormonal status to prevent pregnancy because a woman should not be having a baby when she's starving to death.

Exceptional Cases

Some women have benefited dramatically from the ketogenic diet and have put schizophrenia, bipolar disorder into full remission.

A woman who was infertile became pregnant within four months of starting keto.

Semaglutide Drugs for Weight Loss

In this section, the speakers discuss semaglutide drugs that are used for weight loss.

Semaglutide Drugs

Semaglutide drugs adjust the way that glucose and insulin are managing energy, both in the body and brain, and can produce weight loss.

Good logical shift in diet and exercise could achieve similar weight loss but many people won't do that.

Semaglutide drugs are weight loss drugs similar to fen-phen drugs of the '90s that were banned because some people didn't handle them well.
