THE FOUNDATION —

Built on Systems Science

For decades, medicine has treated the brain and the body as separate systems. Dr. Emeran Mayer has spent his career dismantling that division. The Mayer Model is the result — a comprehensive, evidence-based framework that places the brain-gut-microbiome system at the center of human health.

01

Emergence

The whole is greater than the sum of its parts. Systems exhibit properties and behaviors that do not exist at the individual component level — individual neurons don’t have thoughts, but a network of them does.

02

Feedback Loops

Systems are dynamic and self-regulating. Information flows through reinforcing or balancing loops that dictate how the system adapts, grows, and maintains stability over time.

03

Boundary & Environment

Systems do not exist in a vacuum. They are open networks that constantly interact with and are shaped by their surrounding environment — biological, psychological, and social.

THE FRAMEWORK —

Seven Interconnected
Pillars

Each pillar plays a distinct and measurable role in supporting the brain-gut-microbiome system. Improving one tends to benefit the others. Neglecting one creates vulnerability across the system.

  • 01   Food
  • 02   Exercise
  • 03   Mindfulness
  • 04   Resilience
  • 05   Community
  • 06   Purpose
  • 07   Sleep
Pillar 01

FOOD

01
MOST DIRECT LEVER
Food is the most direct lever we have over the health of our gut and microbiome. The quality, diversity, and timing of what we eat shapes the microbial communities that in turn influence our brain chemistry, immune regulation, and inflammatory state. The Mayer Model emphasizes a plant-rich, fiber-forward, polyphenol-dense approach to eating — one personalized to the individual rather than applied as a rigid prescription.

Pillar 02

EXERCISE

02
SYSTEMIC IMPACT
Exercise does far more than strengthen muscles and the cardiovascular system. Regular physical movement directly promotes gut motility, reduces intestinal permeability, increases microbial diversity, and lowers systemic inflammation. It is one of the most powerful tools available for keeping the brain-gut system functioning well.

Pillar 03

MINDFULNESS

03

NEUROBIOLOGICAL
Mindfulness — encompassing meditation, breathwork, and present-moment awareness — is not a soft add-on, but a neurobiologically grounded intervention. Mindfulness practices modulate the stress response, reduce the brain’s amplification of gut signals, and help regulate the autonomic nervous system signals that travel between brain and gut. For many people with brain-gut disorders, mindfulness is as important as any dietary change.
Pillar 03

RESILIENCE

03

GUT HEALTH STRATEGY
Resilience refers to the capacity to navigate adversity without sustained biological dysregulation. Chronic negative emotions — anxiety, anger, grief, loneliness — are not merely psychological experiences. They alter gut motility, increase intestinal permeability, shift the composition of the microbiome, and drive inflammation. Building resilience is a gut health strategy.

Pillar 05

COMMUNITY

05

UNDERAPPRECIATED
Community is one of the most underappreciated determinants of health. Shared meals, meaningful relationships, and a sense of belonging activate neurobiological pathways that benefit the brain and gut alike. Loneliness, by contrast, is a potent stressor with measurable consequences for gut permeability and immune function.

Pillar 06

PURPOSE

06

EXISTENTIAL FOUNDATION
Purpose — the sense of meaning, connection to something larger than oneself, and a reason to show up — provides a psychological foundation that buffers stress and supports the long-term behavioral consistency that health requires. However one arrives at it, a sense of purpose is associated with better health outcomes across virtually every measure.

Pillar 07

SLEEP

07

RECOVERY WINDOW
Sleep is the brain-gut system’s most essential recovery window. During sleep, the brain clears metabolic waste, the gut undergoes repair, and the microbiome resets its circadian rhythms. Chronic sleep disruption raises cortisol, increases intestinal permeability, reduces microbial diversity, and impairs the brain’s ability to regulate pain and emotion. Prioritizing sleep is not passive — it is one of the most powerful interventions available for restoring balance to the brain-gut-microbiome system.
