Metabolic Psychiatry
in Washington DC

A Whole-Person Approach
to Mental Wellness Through
Brain and Metabolic Health

Functional psychiatry looks beyond symptom checklists. It asks a deeper question:

 

Why is your brain functioning the way it is right now?

 

At Proactive Psychiatry, functional psychiatry combines evidence-informed psychiatric care with a broader look at metabolism, sleep, nutrition, hormones, inflammation, stress physiology, executive function, and lifestyle patterns.

 

This is not “alternative psychiatry.” It is psychiatry with a wider lens.

 

If you are in Washington, DC, Maryland, New York, or Colorado and want a more comprehensive approach to ADHD, anxiety, depression, burnout, sleep issues, or cognitive performance, functional psychiatry may be a good fit.

Metabolic Psychiatry: TL;DR

 

Metabolic psychiatry is an emerging field that examines how metabolism, inflammation, nutrition, sleep, exercise, hormones, and overall physical health affect brain function and mental health.

​

At Proactive Psychiatry, I use a metabolic psychiatry framework alongside evidence-based psychiatric care to better understand conditions such as:

​

  • ADHD

  • Depression

  • Anxiety

  • Burnout

  • Brain fog

  • Fatigue

  • Cognitive dysfunction

  • Mood instability

 

This does not mean mental health conditions are simply metabolic disorders.

 

Rather, it recognizes that the brain is part of the body, and factors such as blood sugar regulation, sleep quality, inflammation, nutrient deficiencies, physical activity, and metabolic health may influence psychiatric symptoms.

​

My goal is to help patients identify potentially modifiable contributors to mental health challenges while still utilizing proven psychiatric treatments when appropriate.

What Is Metabolic Psychiatry?

 

Metabolic psychiatry is a rapidly growing area of research exploring the connection between:

​

  • Brain health

  • Cellular energy production

  • Metabolism

  • Nutrition

  • Inflammation

  • Hormones

  • Physical health

 

The brain represents approximately 2% of body weight yet consumes roughly 20% of the body’s energy.

​

Because the brain is one of the most energy-demanding organs in the body, disruptions in metabolism may contribute to symptoms such as:

​

  • Poor concentration

  • Brain fog

  • Low motivation

  • Fatigue

  • Anxiety

  • Depression

  • Emotional dysregulation

  • Cognitive dysfunction

 

Metabolic psychiatry asks a simple question:

​

Could improving metabolic health help improve mental health?

​

For many patients, the answer may be yes.

Why Metabolic Health Matters for Mental Health

 

Historically, psychiatry focused primarily on neurotransmitters such as:

​

  • Dopamine

  • Serotonin

  • Norepinephrine

 

These neurotransmitters remain important.

​

However, modern research increasingly demonstrates that mental health may also be influenced by:

​

Sleep

 

Poor sleep can affect:

​

  • Mood

  • Attention

  • Impulse control

  • Memory

  • Emotional regulation

 

Even mild chronic sleep deprivation can worsen ADHD, anxiety, and depression symptoms.

​

Blood Sugar Regulation

 

Blood sugar fluctuations may contribute to:

​

  • Irritability

  • Fatigue

  • Cravings

  • Anxiety

  • Brain fog

  • Difficulty concentrating

 

Many patients report improved mental clarity when blood sugar becomes more stable.

​

Inflammation

 

Chronic inflammation has been associated with:

​

  • Depression

  • Cognitive symptoms

  • Fatigue

  • Mood disorders

 

While inflammation is rarely the sole cause of psychiatric symptoms, it may be one contributing factor.

​

Physical Activity

 

Exercise has been shown to support:

​

  • Executive functioning

  • Mood

  • Sleep quality

  • Stress resilience

  • Neuroplasticity

 

Movement remains one of the most powerful lifestyle interventions available.

​

Nutritional Status

 

Deficiencies or suboptimal levels of nutrients such as:

​

  • Vitamin D

  • Iron

  • Vitamin B12

  • Folate

  • Magnesium

  • Omega-3 fatty acids

 

may contribute to symptoms in some individuals.

​

Insulin Resistance

 

Emerging research suggests insulin resistance may be associated with:

​

  • Depression

  • Cognitive impairment

  • Brain fog

  • Reduced energy

 

Addressing metabolic dysfunction may help support overall brain health.

Metabolic Psychiatry and ADHD

 

ADHD is often viewed exclusively through the lens of dopamine and executive function.

​

While these mechanisms are important, ADHD symptoms may also be influenced by:

​

  • Sleep quality

  • Physical activity

  • Nutritional intake

  • Metabolic health

  • Stress

  • Circadian rhythm disruption

 

At Proactive Psychiatry, ADHD treatment often includes discussion of:

​

Sleep Optimization

 

Many adults with ADHD experience:

​

  • Delayed sleep schedules

  • Insomnia

  • Poor sleep quality

 

Improving sleep may improve focus and executive functioning.

​

Nutrition

 

Patients frequently ask about:

​

  • Protein intake

  • Blood sugar stability

  • Omega-3 supplementation

  • Elimination diets

  • Food sensitivities

 

While nutrition is not a cure for ADHD, it can be an important part of comprehensive treatment.

​

Exercise

 

Exercise may support:

​

  • Dopamine signaling

  • Mood regulation

  • Focus

  • Executive functioning

 

For many adults with ADHD, physical activity becomes a critical component of symptom management.

Metabolic Psychiatry and Depression & Mood Disorders

 

Depression is complex and multifactorial.

​

Potential contributors may include:

​

  • Genetics

  • Life stressors

  • Trauma

  • Neurobiology

  • Sleep disorders

  • Medical conditions

  • Metabolic dysfunction

 

Metabolic psychiatry encourages evaluation of factors such as:

​

  • Sleep quality

  • Nutritional status

  • Physical activity

  • Inflammation

  • Hormonal health

  • Insulin resistance

 

For some individuals, improving these factors may complement traditional treatments such as:

​

  • Psychotherapy

  • Medication

  • Behavioral interventions

Metabolic Psychiatry and Anxiety

 

Anxiety symptoms can sometimes be worsened by physiological stressors including:

​

  • Sleep deprivation

  • Blood sugar instability

  • Excess caffeine

  • Chronic stress

  • Sedentary behavior

  • Poor recovery

 

Addressing these factors may help create a stronger foundation for anxiety treatment.

​

Metabolic psychiatry does not replace therapy or medication when needed.

​

Instead, it seeks to optimize the biological environment in which recovery occurs.

What a Metabolic Psychiatry Evaluation May Include

 

Depending on your symptoms and goals, an evaluation may explore:

​

Lifestyle Factors

​​

  • Sleep patterns

  • Exercise habits

  • Nutrition

  • Stress levels

  • Recovery practices

​

Medical History

​​

  • Weight changes

  • Cardiometabolic risk factors

  • Chronic illnesses

  • Hormonal concerns

  • Family history

​

Laboratory Assessment

 

When clinically appropriate, labs may include evaluation of:

​

  • Vitamin D

  • Iron studies

  • B12

  • Folate

  • Thyroid function

  • Metabolic markers

  • Other individualized testing

 

Testing is always guided by clinical judgment and individual circumstances.

​

Others benefit from medication, therapy, coaching, or a combination of approaches.

​

The goal is to use the best available evidence while considering the whole person.

Root Causes of Unwellness

Cause: Improper integration of the pillars of wellness (see below)

> Solution: Reconnect with the pillars through a meaningful evaluation and a thoughtful rebalancing 

​

Cause: Environmental factors 

> Solution: Assess our surroundings to determine what actionable steps we can take to improve our environmental

​

Cause:  A. Perceptional and/or relational factors 

 B. Overwhelming societal constructs (I call this the "square peg in a round hole" problem)

> Solution: Critically reconsider how we respond to and interpret the world around us

​

Cause: Biological and/or chemical factors 

> Solution: Analyze our baseline to determine standard deviation - address with medication where appropriate 

Holistic Pillars of Wellness & Health

Based on the principles of integrative psychiatry

I. Nutrition.

The fuel we put into our bodies impacts our capacity to maximize our cognitive function, physical existence, and longevity. 

​

II. Movement.

Our bodies are made to move in order to survive - without adequate movement and connection with the world around us we are rejecting an evolutionary truth of our existence. 

​

III. Recovery.

The extent to which we recharge determines to our ability to thrive, physically and emotionally.
