Amae Health Featured on Advancements with Ted Danson

If you are comparing TMS, ketamine, and Spravato for depression, you have probably reached the point where standard antidepressants have not done enough. All three are evidence-based options for treatment-resistant depression, and beyond that they have little in common. TMS is a course of magnetic stimulation delivered while you sit awake in a chair. Ketamine is an anesthetic given by IV, used off-label for depression. Spravato is a nasal spray made from esketamine, one of the two mirror-image forms that make up ketamine, with its own FDA approval and its own rulebook.

‍

None of the three is universally better. They differ in mechanism, speed, setting, and monitoring, and the right one depends on your clinical history and how you respond. Treatment-resistant depression generally means depression that has not adequately improved after at least two antidepressants taken at a proper dose for long enough, and that is the group where all three are most often used.

What Is TMS?

Transcranial magnetic stimulation uses a coil placed against the scalp to deliver focused magnetic pulses to the left dorsolateral prefrontal cortex, a region involved in mood regulation. The FDA first cleared TMS for major depressive disorder in 2008, according to the National Institute of Mental Health. It is delivered in an office, with no anesthesia and no medication.

‍

Our standard TMS course runs 20 to 30 daily sessions over four to six weeks, each 30 to 40 minutes long. You stay awake throughout and drive yourself home afterward. In real-world outcome data from 42 U.S. practices, more than half of patients with medication-resistant depression responded to a standard course, and more than a third reached remission.

What Is Ketamine Therapy?

Ketamine has been an FDA-approved anesthetic since 1970. Its use for depression is off-label: prescribed for a purpose the FDA has not formally approved, which is legal and common in medicine but leaves the safeguards less standardized. It is usually given as an IV infusion in a monitored clinic, as a series of sessions over a few weeks.

‍

Ketamine blocks the NMDA receptor, a glutamate receptor, rather than acting on serotonin like standard antidepressants, and that difference is thought to explain its speed. In a landmark 2006 trial, 18 people with treatment-resistant depression received a single infusion of 0.5 mg/kg, and their symptoms improved significantly within 110 minutes. By the next day, 71% had responded and 29% were in remission. One week later, 35% still met the response threshold. Rapid, real, and often short-lived.

‍

The catch is in the monitoring. Ketamine causes dissociation, a sense of detachment from your body or surroundings, plus sedation and blood pressure rises during and after the infusion, so you are observed until those effects pass and cannot drive that day. In a 2017 consensus statement in JAMA Psychiatry, an American Psychiatric Association task force found the evidence for rapid antidepressant effects convincing but the studies small, the longer-term efficacy data lacking, and the safety data on repeated dosing limited.

What Is Spravato (Esketamine)?

Ketamine is a mixture of two mirror-image molecules. Spravato is esketamine, one of those two, delivered as a nasal spray. Unlike IV ketamine, it has FDA approval for depression. The original approval came in March 2019 for treatment-resistant depression alongside an oral antidepressant, a second indication followed for adults with major depressive disorder and acute suicidal thoughts or behavior, and in January 2025 the FDA approved Spravato as a standalone monotherapy for treatment-resistant depression, with no oral antidepressant required, per the current prescribing information.

‍

That approval comes with a rulebook. Spravato can only be given at a setting certified under a Risk Evaluation and Mitigation Strategy (REMS) program: you take the spray under supervision, you are monitored for at least two hours before an assessment clears you to leave, and you cannot drive until the next day after a restful sleep. Its label carries a boxed warning for sedation, dissociation, respiratory depression, abuse and misuse, and suicidal thoughts and behaviors in younger patients.

‍

So is Spravato the same as ketamine? Related, not identical: same molecular family, same receptor, similar rapid onset and dissociative effects, but a different route, a formal FDA indication, and mandatory monitoring rules that off-label ketamine does not carry. For most people comparing TMS vs Spravato, those rules and insurance coverage are the practical differences that matter.

TMS vs Ketamine vs Spravato: Side-by-Side Comparison

Onset and Duration of Effect

Speed is the clearest dividing line. TMS builds gradually, and many people do not notice a clear change until the second or third week or later. Ketamine and Spravato can shift symptoms within hours to days.

‍

Speed and staying power are different things. Ketamine's effect after a single infusion often fades within a week or two, which is why it is given as a series with maintenance dosing. Spravato starts at twice a week and tapers, with the need for continued treatment reassessed along the way. Research on durability is still developing for all three, and none should be described as permanent.

Side Effects and Safety Considerations

TMS side effects are local and short-lived: scalp discomfort where the coil sits, headache, and sometimes brief lightheadedness or facial muscle twitching during the pulses. These usually settle within the first week, and because nothing enters the bloodstream there is no weight gain, sexual dysfunction, or sedation. Seizure is the one serious risk, exceedingly rare, and TMS is not used in people with a seizure history, metal in the head, or implanted electronic devices.

‍

Ketamine and Spravato share a different profile. The most common reactions to Spravato in trials were dissociation, dizziness, nausea, sedation, vertigo, numbness, anxiety, lethargy, increased blood pressure, vomiting, feeling drunk, and headache. Those effects peak in the hours after dosing, which is what the monitoring window is for, and both drugs carry a potential for misuse that shapes who is a candidate. Each option has its own screening, and a contraindication to one does not rule out the others.

Cost and Insurance

For TMS, most commercial insurers cover treatment for major depressive disorder once eligibility criteria are met, typically a confirmed diagnosis and documented antidepressant trials without adequate relief. Prior authorization is standard. For TMS we take all commercial insurance plans, cash pay is available, and authorization is something our intake team manages for you.

‍

Spravato is more commonly covered than off-label ketamine because it has an FDA indication insurers can write criteria around, though prior authorization and documentation of failed antidepressant trials are typically required. Ketamine infusion coverage varies widely, and many clinics are self-pay. Published cost estimates vary so much by dose, frequency, and insurance status that a single dollar figure would mislead; ask each provider and your insurer directly.

Can These Treatments Be Combined?

Sometimes, and the research is early. A 2024 systematic review found six published studies on combining TMS with ketamine, mostly case reports plus one retrospective review and one small pilot, and reported substantial and sustained improvement with generally mild side effects. The authors also said the designs were too varied and the samples too small for firm conclusions, and called for randomized trials.

‍

In practice, TMS and Spravato are sometimes used one after the other. Combining any of these is a clinical judgment a psychiatrist makes from your history, not a general recommendation, and the more common pattern is to use one, assess the response, then decide.

Choosing Between Them: What Influences the Decision

A psychiatrist weighing these options usually works through a short list:

‍

• Treatment history. Which antidepressants, at what doses, for how long, and whether psychotherapy has been tried.
• How urgently relief is needed. When symptoms are severe or suicidal thoughts are present, a faster-acting option may take priority, alongside care for suicidal thoughts.
• Tolerance for the experience. Dissociation and a two-hour monitored window, versus a daily half-hour appointment for several weeks with no drug effects.
• Practical constraints. Whether you can get to daily sessions, whether someone can drive you home after Spravato or ketamine, and what your insurance will authorize.
• Health factors. Seizure history, metal implants, blood pressure, and any history of substance misuse each rule options in or out.
• What else is in place. Any of the three works better inside ongoing psychiatric care and therapy than as a standalone fix.

Making the Decision With an Integrated Care Team

TMS, ketamine, and Spravato are tools, and tools do their best work inside a plan: a psychiatrist who knows your history, a therapist working alongside the biological treatment, and a team that notices when the plan needs to change.

‍

That is how we work. At Amae, our one-team care model combines psychiatry, therapy, primary care, and peer support, and TMS and Spravato are available through our Los Angeles and Bay Area clinics as part of that care. If you have been through the antidepressant cycle and want a clear, unhurried look at what comes next, talk with an Amae psychiatrist about your options. If you are in crisis or thinking about suicide, call or text 988 now.

Frequently Asked Questions

What is the difference between TMS and ketamine for depression?

TMS stimulates the brain with magnetic pulses over a course of daily outpatient sessions, with no drug, no sedation, and no monitoring afterward. Ketamine is a medication that acts on NMDA receptors, given by infusion or, as esketamine, by nasal spray, with monitored sedation and dissociation and often faster but shorter-lived effects.

Is Spravato the same as ketamine?

Related but not identical. Spravato is esketamine, the S-enantiomer of the ketamine molecule, delivered as an FDA-approved nasal spray under a required monitoring program. Ketamine infusions use the full ketamine compound and are prescribed off-label for depression, without an FDA indication for that use.

Is Spravato only approved with an antidepressant?

Not anymore. The original 2019 approval was for use alongside an oral antidepressant, and in January 2025 the FDA also approved Spravato as a standalone monotherapy for adults with treatment-resistant depression. Whether it is used alone or with an antidepressant is a decision your psychiatrist makes based on your situation.

Which works faster, TMS or Spravato?

Spravato. Esketamine and ketamine can produce symptom change within hours to days, while TMS builds gradually across a four-to-six-week course. Faster onset does not mean more durable improvement, and both durability and side effects belong in the comparison.

Can TMS and Spravato be used together?

Sometimes, as a clinical decision made with a psychiatrist based on your individual history. Both can be part of a broader treatment-resistant depression plan alongside medication and therapy, and the evidence on combining them is still early.

Is ketamine or Spravato covered by insurance?

Spravato is more commonly covered, because it has an FDA indication insurers can build criteria around, though prior authorization and proof of failed antidepressant trials are usually required. Coverage for off-label ketamine infusions varies widely and is often self-pay. Confirm with the provider and your insurer before starting.

You're lying awake at 3 AM with your mind racing through tomorrow's worries, yet feeling too drained to care about things you once loved. Your heart pounds during everyday situations, but you're also pulling away from friends and family.

If this sounds familiar, you're not alone — anxiety and depression often appear together, creating a complex web of symptoms that can feel overwhelming. Understanding what's happening in your mind and body, recognizing the signs, and being aware of effective treatments can help you regain control.

If you’re wondering how to ask for help when depressed, start by choosing one trusted person, describing what you’re experiencing in simple terms, and asking for specific support. Professional help from therapists or mental health clinics can provide guidance when symptoms feel overwhelming.

How Are Anxiety and Depression Connected?

The relationship between anxiety and depression is more common than many people realize. Mental health professionals refer to this as "comorbidity" — when two conditions occur together in the same person. Research shows that about half of people diagnosed with major depression also experience significant anxiety symptoms, and vice versa.

These conditions often feed off each other in a cycle that can be difficult to break. Anxiety frequently comes first, with constant worry and fear gradually wearing down your emotional reserves. This mental exhaustion can lead to hopelessness and low energy characteristic of depression. Conversely, when you're depressed and withdrawing from activities, you might develop anxiety about your changing relationships, work performance, or ability to function normally.

The cycle looks like this: persistent worry leads to emotional and physical exhaustion, which triggers a low mood and avoidance behaviors, creating more situations to worry about. Understanding this connection helps explain why treating both conditions together often produces better outcomes than addressing them separately.

What Is Anxiety?

Anxiety is your body's natural alarm system gone into overdrive. While everyone experiences worry and fear sometimes, anxiety disorders involve excessive, persistent worry that interferes with daily life. The core features include hyperarousal (your nervous system staying "revved up") and worry that feels impossible to control.

Common anxiety symptoms include:

• Restlessness or feeling keyed up
• Racing heart or rapid breathing
• Difficulty sleeping or staying asleep
• Stomach upset or digestive issues
• Muscle tension, especially in the shoulders and jaw
• Difficulty concentrating due to racing thoughts

Anxiety disorders come in several forms. Generalized Anxiety Disorder (GAD) involves worry about many different areas of life. Panic disorder features sudden, intense episodes of fear. Social anxiety centers on fear of judgment in social situations, while specific phobias involve intense fear of particular objects or situations.

What Is Depression?

Depression goes far beyond temporary sadness or "having a bad day." It's a persistent condition that affects how you think, feel, and function. The hallmark features include prolonged low mood, loss of interest or pleasure in activities you once enjoyed, and significant fatigue that is not relieved by rest.

Depression also commonly involves feelings of guilt or worthlessness, difficulty concentrating or making decisions, changes in appetite and sleep patterns, and physical symptoms like headaches or unexplained aches. In severe cases, people may have thoughts of death or suicide.

Signs You May Have Both Disorders

When anxiety and depression occur together, symptoms can overlap and intensify each other. You might notice both the hyperarousal of anxiety and the low energy of depression, creating an exhausting internal conflict between feeling wired and tired simultaneously.

Watch for these combined symptoms:

• Racing thoughts mixed with feelings of hopelessness
• Fatigue coupled with restlessness or inability to sit still
• Difficulty sleeping due to both worry and low mood
• Loss of appetite from anxiety alongside changes in eating changes
• Avoiding social situations due to both fear and lack of interest
• Physical symptoms like headaches, rapid heartbeat, and muscle tension
• Irritability that stems from both anxiety and depression
• Trouble concentrating, whether from racing thoughts or mental fog
• Withdrawing from activities you once enjoyed
• Feeling overwhelmed by everyday tasks and decisions

If these symptoms are affecting your work, relationships, or daily functioning for two weeks or more, it's time to seek professional help.

How Clinicians Diagnose

Mental health professionals use several approaches to diagnose anxiety and depression. The process typically begins with a comprehensive clinical interview where you'll discuss your symptoms, their duration and severity, family history, and how they're impacting your life.

Your clinician will also rule out medical causes, as conditions like thyroid disorders, heart problems, or certain medications can mimic anxiety and depression symptoms. Blood tests or other medical evaluations might be recommended.

Many professionals use brief, standardized screening tools like the GAD-7 for anxiety and the PHQ-9 for depression. These questionnaires help quantify symptom severity and track improvement over time. At Amae Health, our clinicians combine thorough interviews with these validated assessments to ensure accurate diagnosis.

Getting a clear diagnosis is crucial because it guides treatment decisions. When both conditions are present, integrated treatment approaches that address the relationship between anxiety and depression tend to be most effective.

Evidence-Based Treatment for Anxiety and Depression

Psychotherapy

Several types of therapy have strong research support for treating anxiety and depression together. Cognitive Behavioral Therapy (CBT) is often considered the gold standard, helping you identify and change negative thought patterns that fuel both conditions. You'll learn to recognize cognitive distortions — like catastrophic thinking that worsens anxiety or all-or-nothing thinking that deepens depression.

For anxiety specifically, exposure therapy gradually helps you face feared situations in a safe, controlled way. This reduces avoidance behaviors that often contribute to depression as well. For depression, behavioral activation focuses on gradually re-engaging with meaningful activities, which can also reduce anxiety by providing structure and accomplishment.

Medications

Several medications effectively treat both anxiety and depression simultaneously. Selective Serotonin Reuptake Inhibitors (SSRIs) and Serotonin-Norepinephrine Reuptake Inhibitors (SNRIs) are typically first-line treatments because they address the underlying brain chemistry involved in both conditions.

These medications typically take 4-6 weeks to show full benefits, although some people may notice improvements earlier. Common side effects may include initial nausea, headaches, or changes in sleep patterns, but these often improve as your body adjusts. Your prescriber at Amae Health will closely monitor your progress, adjusting dosages as needed and watching for any concerning side effects.

It's essential to work closely with your healthcare provider throughout the medication process, as finding the right medication and dosage can be a time-consuming and patient process.

Lifestyle & Skills

Lifestyle changes play a crucial role in managing both conditions. Maintaining a consistent sleep schedule helps regulate mood and reduce anxiety. Regular exercise — even just 20-30 minutes of walking daily — can be as effective as medication for mild to moderate depression and significantly reduces anxiety symptoms.

Limiting alcohol and caffeine helps stabilize mood and reduce physical anxiety symptoms. Simple coping skills can also make a significant difference:

• Deep breathing exercises to calm your nervous system
• Grounding techniques using your five senses during anxiety spikes
• Setting aside "worry time" to contain anxious thoughts
• Progressive muscle relaxation to reduce physical tension

For individuals who don't respond adequately to standard treatments, options like Transcranial Magnetic Stimulation (TMS) may be considered as additional treatment approaches.

When to Seek Urgent Help

While anxiety and depression are treatable conditions, certain warning signs require immediate attention. Please seek emergency help if you or someone you know experiences suicidal thoughts, plans, or intentions, self-harm behaviors, inability to care for basic needs like eating or hygiene, signs of psychosis such as hallucinations or delusions, or dangerous substance use that puts safety at risk.

How Our Amae Health Clinic Can Help

At Amae Health, we understand the complex relationship between anxiety and depression and offer comprehensive, integrated care. Our approach begins with a same-week evaluation where our experienced clinicians conduct thorough assessments to understand your unique situation.

Metabolic psychiatry is an emerging field that examines how metabolic dysfunction (insulin resistance, mitochondrial problems, and chronic inflammation) affects brain function.Rather than treating symptoms alone, it looks at the metabolic factors that may underlie conditions such as depression, bipolar disorder, and schizophrenia. The interest is strongest in complex mental illness, where standard treatment often falls short and where physical and psychiatric problems tend to travel together. This article explains the science behind the field, the therapies it uses, the evidence so far, and who researchers think it may help, along with the honest limits of what is still an early area of study.

What Is Metabolic Psychiatry?

Metabolic psychiatry views serious mental illnesses not solely as chemical imbalances or psychological phenomena, but as conditions also connected to disruptions in brain energy metabolism, inflammation, and cellular health. It does not discard the standard understanding of psychiatric illness. It adds a layer, asking whether the way the brain produces and uses energy is part of the picture.

‍

The term was introduced in 2015 by Dr. Shebani Sethi, who founded the first academic metabolic psychiatry clinic and research program at Stanford University after noticing how often her patients with treatment-resistant psychiatric conditions also had metabolic problems. The approach builds on more than a century of ketogenic-therapy research in neurology, where the ketogenic diet has long been used to treat drug-resistant epilepsy. Metabolic psychiatry is still emerging, and reputable clinicians frame it as a promising area of research rather than a finished or proven model of care.

The Link Between Metabolism and Mental Health

The brain is an energy-hungry organ. It makes up about 2% of body weight but uses roughly 20% of the body's energy, and it depends on a steady fuel supply to function. When metabolism breaks down, through insulin resistance, unstable blood sugar, or chronic inflammation, the brain can struggle to access the energy it needs, and researchers believe this may contribute to psychiatric symptoms.

‍

The connection runs in both directions. Roughly a third of people with schizophrenia or bipolar disorder also have metabolic syndrome, a cluster of conditions including high blood sugar, high blood pressure, and abnormal cholesterol (Vancampfort et al., World Psychiatry, 2015). People living with serious mental illness carry roughly 1.5 to 2 times the risk of metabolic syndrome and type 2 diabetes compared with the general population, an elevation driven partly by the illness, partly by medication side effects, and partly by shared biology. This is an association, not proven causation. But it is strong and consistent enough that the field takes it seriously.

How Does Metabolic Psychiatry Work?

The central idea, articulated most fully in Dr. Chris Palmer's Brain Energy theory, is that many mental disorders may be, in part, metabolic disorders of the brain. Palmer, a psychiatrist at McLean Hospital and Harvard Medical School, places mitochondria, the structures that produce energy inside cells, at the center of the model.

‍

Here is the mechanism in plain terms. When brain cells cannot get or use energy properly, often because insulin resistance blocks glucose from entering cells, it can trigger a cascade: mitochondrial dysfunction, oxidative stress, and inflammation. That cascade can disrupt neurotransmitters and interfere with the brain regions that regulate mood, thinking, and perception. Metabolic therapies aim to work upstream of that cascade, restoring the brain's energy supply and lowering inflammation rather than only adjusting neurotransmitters downstream. The theory is compelling and biologically plausible, and it remains a theory under active investigation, not settled fact.

Metabolic Therapies Used in Metabolic Psychiatry

One point clinicians in this field stress is that the toolkit is broader than a single diet. Metabolic health is shaped by many inputs, and a metabolic approach typically addresses several at once:

‍

• Ketogenic therapy: the clinically supervised use of a well-formulated ketogenic diet to shift the brain toward ketones as fuel (the cornerstone intervention, covered below).
• Nutritional changes: reducing sugar, ultra-processed foods, and refined carbohydrates.
• Intermittent fasting: may improve insulin sensitivity and reduce inflammation.
• Exercise: improves insulin sensitivity, supports mitochondrial function, and reduces inflammation.
• Sleep optimization: poor sleep worsens insulin resistance and mitochondrial function.
• Stress management: chronic stress raises cortisol, which disrupts glucose regulation.
• Removing metabolic stressors: reducing smoking, excess alcohol, and sedentary time.

‍

Several of these are ordinary lifestyle measures. What is different in metabolic psychiatry is the reason behind them: they are used deliberately to improve brain energy metabolism, tracked with lab data, and coordinated with conventional psychiatric care.

Ketogenic Therapy: The Cornerstone Intervention

The ketogenic diet was developed more than a century ago to treat drug-resistant epilepsy, and that long neurological track record is part of why it draws the most research attention in psychiatry. A ketogenic diet is very low in carbohydrates, which shifts the body into nutritional ketosis: the liver begins converting fat into ketones, an alternate fuel the brain can use when insulin resistance limits its access to glucose.

‍

Beyond supplying fuel, ketones may reduce inflammation, lower oxidative stress, support mitochondrial function, and help rebalance neurotransmitters. Those are plausible mechanisms, and they are still being studied.

‍

The most important thing to understand is that ketogenic therapy, as used in this field, is a clinical intervention, not a do-it-yourself diet. It is supervised by clinicians, monitored with regular lab work, and integrated with a person's other treatment. It is not presented by responsible practitioners as a cure, and it is not a replacement for medication. Any change to psychiatric medication belongs in the hands of a treating clinician who knows the person's history.

What Does a Metabolic Psychiatry Evaluation Involve?

A metabolic approach usually starts with screening that goes beyond a standard psychiatric assessment, adding blood work to build a picture of a person's metabolic health. That panel commonly includes:

‍

• Fasting glucose and insulin, plus hemoglobin A1C, to assess blood sugar regulation
• A lipid panel: triglycerides, HDL, and LDL
• A thyroid panel
• Inflammatory markers such as C-reactive protein (CRP)
• Key vitamin and mineral levels, including B12, folate, magnesium, and omega-3s

‍

The point of this data is not to produce a standalone diagnosis. It is to identify metabolic factors a clinician can address alongside conventional psychiatric care, and to establish a baseline that lab work can track over time.

Metabolic Psychiatry vs. Standard Psychiatry

Metabolic psychiatry is best understood as a complement to standard psychiatric care, not a replacement for it.

‍

‍

The honest framing matters. Standard psychiatry, medication and therapy, remains the evidence-based foundation. Metabolic psychiatry adds a layer that some clinicians and researchers believe addresses root-cause biology, and it works best woven into conventional treatment rather than substituted for it.

How Metabolic Psychiatry Fits Within Precision Psychiatry

Metabolic psychiatry is often considered part of the broader precision psychiatry movement, which tailors treatment to each person's unique biology rather than applying population averages. Both reject one-size-fits-all, trial-and-error prescribing in favor of care informed by an individual's own data. Metabolic screening is one example of that data. Precision psychiatry is the larger shift, and it is the philosophy behind research programs like the Amae Institute, which studies how to match people living with complex conditions to more effective, individualized care.

Who Might Benefit from Metabolic Psychiatry?

Research and clinical interest are concentrated in complex mental health conditions, the situations where standard treatment most often falls short. The strongest focus so far has been on:

‍

• Bipolar disorder and schizophrenia, where metabolic syndrome is common and where the first clinical trials have concentrated. People navigating a recent diagnosis can learn more about bipolar disorder treatment and how it is managed within an integrated model.
• Treatment-resistant depression, where conventional approaches have not produced adequate relief.
• People with co-occurring metabolic conditions such as insulin resistance, type 2 diabetes, or obesity.
• People who have not responded well to, or cannot tolerate, standard treatments.

‍

Two caveats belong with every one of these. The field is emerging, so the evidence is still being built. And metabolic therapies are used alongside, not instead of, conventional psychiatric care, always under medical supervision. Whether a metabolic approach is appropriate for any individual is a clinical judgment, made by a clinician who knows that person's full history.

The Evidence So Far

The evidence is a mix of a strong foundation and promising but early results. Ketogenic therapy has more than a century of established use in epilepsy, which gives the underlying biology real credibility. For psychiatric conditions specifically, the picture is younger.

‍

In 2024, a Stanford pilot trial led by Dr. Sethi followed more than 20 adults with bipolar disorder or schizophrenia who also had metabolic abnormalities through a four-month ketogenic intervention. It was the first U.S. clinical trial of a ketogenic diet for serious mental illness since 1965. Most participants showed improvement in their psychiatric symptoms, reduced medication-related weight gain, and better metabolic markers; by the study's end, none still met the criteria for metabolic syndrome (Sethi et al., Psychiatry Research, 2024). It was a small, single-arm pilot, not a randomized controlled trial, so the results are encouraging rather than definitive.

‍

Alongside trials like this, case series and clinical reports describe stabilized mood and, in some cases, reduced reliance on medication under supervision. Larger, more rigorous randomized trials are now underway (Nature Mental Health, 2026). The honest summary: a solid mechanistic foundation, genuinely promising early psychiatric results, and a field that still needs bigger and better-controlled studies before anyone can call it established.

A Whole-Person Approach at Amae Health

The logic underneath metabolic psychiatry, that physical and mental health are not separate systems, is the same logic behind integrated care. At Amae Health, primary care physicians and registered dietitians are part of the psychiatric care team, so physical health, nutrition, sleep, and metabolic comorbidities are treated alongside mental health rather than as an afterthought. That is not the same as offering a specific metabolic-psychiatry program, but it reflects the same whole-person, precision-oriented conviction: complex conditions deserve care that looks at the whole biology of a person.

Frequently Asked Questions

What is metabolic psychiatry?

Metabolic psychiatry is an emerging field that addresses metabolic dysfunction, such as insulin resistance, mitochondrial problems, and inflammation, that may affect brain function and mental health. It targets underlying metabolic factors alongside, not instead of, conventional psychiatric care.

‍

How does metabolic psychiatry work?

The brain depends on a steady energy supply. When metabolism is disrupted, often through insulin resistance that keeps cells from using glucose, the brain can struggle to access fuel, which researchers believe may worsen psychiatric symptoms. Metabolic therapies aim to restore that brain energy and reduce inflammation, working upstream of the neurotransmitter changes that standard treatment targets.

‍

What is ketogenic therapy for mental health?

It is the clinically supervised use of a well-formulated ketogenic diet to shift the brain toward ketones as fuel. Originally developed for epilepsy, it is the most-studied metabolic therapy for serious mental illness. It is used under medical supervision with regular lab monitoring, not as a do-it-yourself diet.

‍

Is metabolic psychiatry evidence-based?

Ketogenic therapy has strong evidence in epilepsy. For psychiatric conditions, the evidence is emerging: promising pilot studies and the early stages of larger trials, but still preliminary. It is used alongside conventional care, not in place of it.

‍

Can metabolic psychiatry replace medication?

No. It is designed to complement conventional psychiatric care, not replace it. Some people reduce their reliance on medication under close medical supervision, but changing psychiatric medication should never be attempted alone.

‍

Who is metabolic psychiatry best for?

Research has focused most on bipolar disorder, schizophrenia, and treatment-resistant depression, especially alongside co-occurring metabolic conditions. A clinician who knows the person's history determines whether a metabolic approach is appropriate. Support is available, and no one should navigate a serious condition alone.
