Metabolic psychiatry and brain energy theory
Bipolar 1 disorder
The experts we follow agree on this.
Mental illnesses are symptoms of metabolic dysfunction affecting the whole body and brain, not just isolated brain problems.
Who is behind it
Doctors, scientists and coaches who teach publicly.

Mostly expert experience so far, with published research still catching up.
In their words
“Mental illnesses are symptoms of metabolic dysfunction affecting the whole body and brain, not just isolated brain problems.”
a Harvard Medical School psychiatrist specializing in metabolic psychiatry
The root cause of mental illness is metabolic dysfunction affecting the brain, which unifies all known risk factors and explains symptoms scientifically.
Recent research over the last 20 years has expanded understanding of mitochondria beyond energy production, highlighting their critical role in various diseases and health conditions.
Mental illness is caused by metabolic brain dysfunction or neuro-metabolic dysfunction, and improving mitochondrial function can put illness into remission.
Mental illnesses may be linked to metabolic dysfunction similar to cancer cells being metabolically sick, suggesting that addressing metabolic health could improve mental health.
Mental and metabolic disorders are in a complex feedback cycle, and treating the body is essential to effectively treat the brain.
Mental disorders are metabolic disorders of the brain characterized by impaired cellular energy production due to ineffective glucose use.
Increasing cellular energy via ketones helps brain cells function normally immediately and supports long-term repair and resilience.
Mental illnesses are treatable metabolic brain disorders, and understanding them this way offers new ways to treat and hope for recovery.
The expert builds on decades of research to present a coherent theory linking metabolism and mitochondria to mental illness, emphasizing their importance in understanding mental health.
Mental illnesses are metabolic disorders of the brain, not disorders of willpower or character, and should be treated as such.
Mental illness is linked to metabolic health, and addressing metabolic factors can provide new solutions and hope for healing.
The same biological processes causing obesity, diabetes, and cardiovascular disease cause brain malfunction leading to mental illnesses, unifying these conditions under the brain energy theory of mental illness.
Understanding the science and biology shows mental health symptoms are caused by physical processes affecting brain energy and function, not just psychological factors or personal weakness.
The Brain Energy theory integrates biological, psychological, and social research into one unifying framework for explaining and treating mental illness.
Understanding mitochondrial function helps make sense of mental illness and leads to treatments that can heal the brain and put chronic disorders into remission.
Metabolic treatments can put chronic, serious disorders like bipolar disorder and schizophrenia into remission, challenging the idea that these are lifelong, untreatable conditions.
Restoring metabolic health through dietary intervention can profoundly improve mental health symptoms, as seen in a patient who lost 160 lbs and experienced remission of psychotic symptoms.
The same biological processes causing obesity, diabetes, and cardiovascular disease also cause brain malfunction leading to mental illnesses or symptoms.
Chris Palmer advocates for treating mental health conditions by addressing the metabolic health of the brain, which is a revolutionary approach beyond traditional psychiatric methods.
Chris Palmer promotes his book 'Brain Energy' as a source for understanding and applying this metabolic approach to mental health (own brand, commercial interest).
Brain metabolism decreases profoundly around perimenopause and menopause due to declining ATP levels in brain cells linked to estrogen decrease.
Estrogen is a very powerful regulator of metabolism throughout the body and plays a critical role in brain function.
Most mental disorders are a direct result of a metabolic breakdown in the brain, suggesting metabolic interventions could improve mental health.
Mental disorders are actually metabolic disorders of the brain, influenced directly by metabolism affecting brain cell function and structure.
Mitochondria play a powerful role in the production and regulation of neurotransmitters, hormones, inflammation, and gene expression, which are all key factors in mental illness and health.
Mental disorders are intricately linked to metabolic disorders like obesity and diabetes, supported by decades of clinical, neuroscience, genetic, neuroimaging, metabolic, and aging research.
Diet, stress, and inflammation are major drivers of mitochondrial dysfunction, which contributes to mental illness and metabolic disorders.
Eating excessive or toxic foods impairs mitochondria and can lead to obesity by affecting hunger and fat cell metabolism.
Stress impairs mitochondrial function in certain cells by diverting metabolic resources to the fight or flight response.
Inflammation impairs mitochondrial function, contributing to symptoms of mental illness and metabolic disorders.
Mental health conditions such as schizophrenia, bipolar disorder, and chronic depression can be prevented and treated by addressing metabolism and mitochondrial function.
Metabolic health is mental health with some of the factors involved and mitochondria playing a role on both sides of the equation.
Mental disorders are metabolic disorders of the brain, with mitochondria as the unifying factor connecting biopsychosocial factors.
Mitochondria play primary roles in how the human body and cells function, explaining connections between inflammation, hormones, neurotransmitter dysregulation, gut microbiome, stress, trauma, and metabolic syndrome in mental disorders.
Understanding metabolism is fundamental to understanding how obesity, diabetes, cardiovascular disease, and mental disorders connect at the cellular level.
Starting with one metabolic treatment and gradually adding others as metabolism improves can increase energy and motivation, facilitating further positive changes.
With care
Some of the minds attach conditions. These are worth reading before you begin.
There is a connection between the level of insulin resistance and the severity of depression.
Alcoholics have metabolically compromised reward pathways due to insufficient glucose fuel, but alcohol-derived acetate partially fuels these brain cells.
Metabolic treatments such as diet and exercise are real treatments that can keep the heart alive and healthy and may do the same for the brain in serious mental illness.
Talk it through
Entrain shows what the experts teach, so you can make better decisions with your own clinician. It does not diagnose or prescribe. If something is worrying you, start there.
How this reading was made
Every line here comes from a doctor, scientist or coach speaking publicly, and links to the moment they said it. Entrain listens for where independent experts arrive at the same place on their own, and shows where they part ways. Mostly expert experience so far, with published research still catching up.
