What Happens to Your Brain When You Eat Sugar?

Your brain fog, afternoon crash, and post-meal irritability aren't random — they're your nervous system responding to blood sugar instability. This article breaks down exactly how your brain controls glucose regulation through the autonomic nervous system, what's really happening during a sugar crash, and two simple, science-backed habits (meal sequencing and post-meal walking) that can reduce blood sugar spikes by up to 40% — no restrictive dieting required. Whether you're dealing with reactive hypoglycemia, chronic fatigue, or trying to protect your long-term cognitive health, understanding the glucose-brain connection is the first step to lasting metabolic wellness.

Your Pain Isn’t in the Tissue. It’s in the Map.

Chronic pain is often not a reflection of ongoing tissue damage, but a dysfunction in how the brain maps and processes the body. As the nervous system becomes sensitized, pain signals amplify and persist even without injury, driven by a degraded cortical map and dysregulated brain–body communication. Neuro-orthopedic rehabilitation restores this map through precise, intentional movement and neurological retraining, while regenerative medicine addresses lingering tissue dysfunction. Together, these approaches break the chronic pain cycle by targeting both the central nervous system and peripheral inputs.

What Separates a Good Athlete from a Great One

Youth athletic performance is driven by nervous system development, not just physical training. Proper nutrition, recovery, sleep, and autonomic balance (HRV) determine how well the brain and body adapt, learn, and perform. Supporting these systems is what separates good athletes from great ones.

Spring Has Always Known What your body is waiting to release and how to let it go safely

Spring is a natural time for detox, but modern detox methods often miss the mark. This article explains how fat loss releases stored toxins and why symptoms like fatigue and brain fog can appear during dieting or fasting. Learn how to properly support your body’s detox pathways—including liver function, gut health, bile flow, and fiber intake—for safe and effective detoxification. Discover why sequencing matters, how to avoid common detox mistakes, and how to optimize weight loss without overwhelming your system.

How Our Most Difficult Patients Changed the Way We Practice

Patients with chronic fatigue, brain fog, and post-viral symptoms are often told their lab results are “normal”—yet they still don’t feel well. This blog explains how underlying issues like mitochondrial dysfunction, poor cellular energy production, and autonomic nervous system imbalance can go undetected in standard care. By combining advanced therapies such as qEEG brain mapping, neurofeedback, hyperbaric oxygen therapy (HBOT), ozone therapy, and photobiomodulation (laser therapy), this approach targets the root cause of chronic illness. The focus is on restoring energy at the cellular level, improving brain function, regulating the immune system, and helping the body return to a true state of recovery.

Everyone's Telling You to Max Out Your Protein.

Protein has become one of the most aggressively promoted nutrients in modern nutrition, but more is not always better. In this article, we break down what the science actually shows about protein intake, how the body uses amino acids, and why muscle growth depends on more than simply increasing protein. Learn how metabolic health, training stimulus, and individualized nutrition determine how effectively your body uses protein.

Five Years After COVID Changed Everything: What We Now Understand About the Brain, the Immune System, and Why So Many People Never Fully Recovered

Five years after the COVID-19 pandemic reshaped global health, the medical community is still uncovering how the virus altered the relationship between the brain and immune system. While many recovered quickly, a significant number of people developed lingering symptoms such as brain fog, fatigue, autonomic dysfunction, and chronic inflammation. Emerging research suggests that COVID was not simply a respiratory infection—it disrupted immune signaling, brain inflammation pathways, and the protective barriers that regulate communication between the body and the nervous system. These disruptions help explain why some individuals never fully returned to baseline health and why symptoms can persist for months or even years. This article explores what clinicians and researchers now understand about post-COVID immune dysfunction, neurological symptoms, and why a growing number of patients require a more integrated brain-immune recovery approach.

The Injury Nobody’s Measuring

Most people are told to rest after a brain injury and wait for the fog to lift. But for the patients still struggling months or years later, rest isn't enough — and Dr. Justin Dearing explains why. In this article, Dr. Dearing reframes brain injury as a systems-level autonomic injury that cascades across blood flow, heart rate, digestion, stress physiology, and cognitive function all at once. Drawing on The Dearing Clinic's multi-omics diagnostic approach — including qEEG brain mapping, eye movement assessment, autonomic stress testing, gut diagnostics, and more — he outlines why passive recovery fails so many patients and what active, measured, sequential intervention actually looks like. At the center of it all is a compelling case study: a former professional football player initially labeled with early-onset dementia whose cognitive decline turned out to be multi-system dysregulation — measurable, correctable, and ultimately reversible. If you or someone you love is still symptomatic after a brain injury and has been told their imaging looks fine, this is the article that reframes everything.

Your 40s Determine Your 70s: The Decade That Decides Everything

Your 40s aren't the beginning of the end — they're the most important decade for determining the quality of your life at 70 and beyond. Dr. Justin Dearing breaks down why the signals your body is sending right now matter more than you think, and what most doctors are missing. If you've been told you're "fine" but don't feel fine, this is worth your next 10 minutes.

The Rhythm Your Immune System Needs and What Happens When Your Gut Loses It

Explore how a balanced gut-brain-immune rhythm is foundational to wellness — and what happens when it’s disrupted. In this article from The Dearing Clinic, Dr. Justin Dearing explains that your immune system follows a daily rhythm governed by the autonomic nervous system, and when that rhythm falls out of balance, symptoms like food sensitivities, brain fog, chronic fatigue, and heightened immune reactivity often emerge. Rather than viewing these as separate issues, he shows how a breakdown in the gut-brain-immune axis creates a self-reinforcing cycle of inflammation, nervous system hypervigilance, and microbiome imbalance — and why addressing the underlying mechanisms, not just symptoms, is key to lasting health.

The 7-Day Neuro-Metabolic Breathing Reset: Why You'll Feel Different Before You Understand Why

Most adults breathe 16-20 times per minute without realizing that anything over 12-14 breaths per minute keeps their nervous system in chronic stress mode. This subtle hyperventilation blocks oxygen delivery, depletes dopamine, drives inflammation, and prevents other health interventions from working—no matter how perfectly you're doing everything else. This 7-day protocol teaches you the breathing mechanics your body was designed to use, with measurable changes in HRV, sleep quality, and nervous system function. You'll feel the difference before you understand the neuroscience behind why it works.

Monitoring What Matters: The Case for Neuro-Metabolic Surveillance in Dementia Prevention

Dementia prevention begins long before memory symptoms appear. By understanding how metabolic health and brain function interact, neuro-metabolic surveillance offers a proactive framework for identifying imbalances early and supporting healthy cognitive aging.

Vitamin C: The Regenerative Foundation Functional Medicine Forgot

Vitamin C is not a supplement — it’s the infrastructure your body relies on to repair, regenerate, and maintain itself. From collagen synthesis and vascular integrity to mitochondrial protection and immune regulation, every regenerative process depends on adequate Vitamin C availability. At The Dearing Clinic, we’ve seen firsthand how high-dose intravenous Vitamin C transforms outcomes when used to prepare the body for regenerative therapies. This article explores why oral supplementation falls short, why formulation matters, and how optimizing the body’s terrain changes everything about healing, performance, and longevity.
