Most people think of mental health as a brain issue. You feel anxious? It must be your GABA, and we reach for Xanax. You’re struggling with focus? Maybe your dopamine is off, grab the Adderall! You’re feeling low? Time to boost your serotonin and pop some SSRIs!
Wrong!
Your brain is an energy-hungry organ, and metabolic health plays a major role in how well it functions. If your blood sugar is unstable, your mitochondria are underperforming, or inflammation is ramped up, your mental health will suffer—no matter how many serotonin-boosting medications you take.
This is the foundation of metabolic psychiatry, a growing field that connects the dots between metabolic dysfunction and mental health conditions like depression, anxiety, ADHD, and cognitive decline.
As a psychiatric nurse practitioner (PMHNP) specializing in integrative and metabolic psychiatry, I take a data-driven approach to mental health. Instead of just managing symptoms, I help patients optimize the root causes of dysfunction so their brain and body work better together.
Let’s dive into the most commonly asked questions about metabolic psychiatry and why this approach is gaining traction.
What Is a Metabolic Psychiatrist?
A metabolic psychiatrist (or psychiatric NP specializing in metabolic health) treats mental health conditions by optimizing metabolic function. This includes assessing and addressing:

✅ Blood sugar dysregulation – Highs and lows in glucose can create mood instability, fatigue, and brain fog.
✅ Mitochondrial dysfunction – Your brain relies on mitochondria for energy production. If they’re sluggish, you’ll feel sluggish—mentally and physically.
✅ Inflammation and oxidative stress – Chronic inflammation is strongly linked to depression and cognitive issues.
✅ Nutrient deficiencies – Essential vitamins and minerals (B12, magnesium, omega-3s, zinc) play key roles in neurotransmitter production.
✅ Hormonal imbalances – Thyroid, cortisol, and sex hormones can make or break mental resilience.
✅ Gut-brain connection – The microbiome directly affects mood, cognition, and even impulse control.
Instead of simply prescribing a medication, a metabolic psychiatrist evaluates the full picture—labs, lifestyle, nutrition, and metabolic function—to build a personalized treatment plan.
What Is a Metabolic Screening for Psychiatry?
A metabolic screening is a comprehensive lab workup that assesses key factors affecting brain health.
Standard Psychiatry vs. Metabolic Psychiatry
Approach | Standard Psychiatry | Metabolic Psychiatry |
Assessment | Symptom-based | Data-driven |
Treatment | Medication & therapy | Metabolic optimization + targeted treatment |
Testing | Often limited to basic labs (if any) | Full metabolic screening |
A metabolic screening may include:
• Fasting glucose & insulin levels → Blood sugar stability is key for focus, mood, and energy.
• Hemoglobin A1C → Long-term blood sugar regulation, linked to cognitive health.
• Lipid panel (LDL, HDL, triglycerides, LDL-P) → Cholesterol impacts brain function and inflammation.
• Thyroid panel (TSH, Free T3, Free T4, Reverse T3) → Even subtle dysfunction can mimic anxiety and depression.
• Inflammatory markers (CRP, homocysteine, ferritin) → Chronic inflammation is a silent driver of mental illness.
• Vitamin & mineral levels (B12, folate, magnesium, zinc, selenium, omega-3s) → Deficiencies can cause brain fog, anxiety, and low motivation.
By testing these markers, we don’t have to guess what’s wrong—we can pinpoint areas for intervention.
What Is Metabolic Therapy for Mental Health?
Metabolic therapy refers to using lifestyle interventions, nutrition, and targeted supplementation to improve brain energy metabolism and neurotransmitter balance.
One of the most well-researched metabolic therapies for psychiatric conditions is the ketogenic diet.
One Example: How the Keto Diet Impacts ADHD (and Other Conditions)
Note: I don't necessary endorse the keto diet or other diets, but it is really important to have the conversation.

Research suggests that a ketogenic diet (high-fat, low-carb, moderate protein) may help ADHD symptoms by stabilizing brain energy levels, reducing inflammation, and supporting neurotransmitter function.
• Ketones as Brain Fuel: Unlike glucose, ketones provide a more stable and efficient energy source for the brain.
• Dopamine Regulation: Ketogenic diets may help balance dopamine signaling, reducing hyperactivity and impulsivity.
• Neuroinflammation Reduction: Chronic inflammation disrupts focus and cognition—ketosis has anti-inflammatory effects.
A study discussed in ADDitude Magazine found that children with epilepsy and co-occurring ADHD symptoms showed improved impulse control and attention on a ketogenic diet.
While keto isn’t for everyone, it highlights the power of metabolic therapy in psychiatric care.
Other metabolic therapies include:
✅ Mediterranean diet → High in omega-3s, antioxidants, and fiber to support brain health.
✅ Intermittent fasting → Can improve brain plasticity, dopamine balance, and cognitive resilience.
✅ Targeted supplements → Magnesium, L-theanine, omega-3s, and adaptogens for stress resilience.
What Does a Metabolic Doctor Do?
A metabolic psychiatrist (or psychiatric NP with a metabolic focus) acts as a brain and body systems optimizer. The goal is to move beyond symptom suppression and focus on root cause resolution.
Mind-Body Connection: Why Mental and Physical Health Are Inseparable
Many people separate mental and physical health, but they are deeply connected:
• Inflammation → Chronic inflammation can lead to anxiety and depression.
• Blood Sugar Instability → Spikes and crashes in blood sugar contribute to mood swings and fatigue.
• Thyroid Dysfunction → A sluggish thyroid can mimic depression; hyperthyroidism can trigger anxiety.
• Gut Health → 90% of serotonin is made in the gut—if your microbiome is off, your mood will be too.
The brain doesn’t function in isolation—mental health is a full-body process.
Why Data-Driven Psychiatry Is the Future
Traditional psychiatry often relies on trial and error:
“Try this medication and see how you feel in six weeks.”
Metabolic psychiatry relies on objective data:
“Let’s measure your metabolic health, fix the underlying dysfunction, and track progress with real biomarkers.”
This personalized approach allows for:
✅ Faster, more effective treatment
✅ Fewer medication side effects
✅ Long-term mental resilience
No two people are the same. Mental health treatment shouldn’t be one-size-fits-all.
How to Get Started
If you’re tired of the conventional mental health treadmill, where medications are the only solution and deeper issues aren’t addressed, it’s time for a different approach.
Metabolic psychiatry isn’t about rejecting medications—it’s about making sure your brain and body are optimized so that any treatment works better.
