| 01 Apr 2025 | EP03: Practitioner Missteps in Resolving Metabolic Dysfunction | 00:40:10 | |
Most cases of type 2 diabetes could be predicted—and prevented—if we knew how to recognize the earliest metabolic red flags hiding in plain sight.
What if your patient’s “normal” labs are quietly pointing to dysfunction—and no one’s looking closely enough to catch it? In this episode, Tracy Harrison shares the story of Jane, a woman in her 40s who feels fine today but is on a predictable path to type 2 diabetes within the next decade. Her fasting glucose and A1C may look great now, but behind the scenes, rising insulin or C-peptide levels are already telling a different story.
Tracy walks through the subtle signs of early metabolic dysfunction and why standard lab markers often lull both patients and practitioners into a false sense of security. She pushes for a shift in perspective: What do we make of “optimal” labs when the patient’s diet, stress, or symptoms tell a different story? What can we catch early if we pay closer attention to things like reactive hypoglycemia, eating hygiene, and even overlooked contributors like toxin exposure and gut motility?
From the pancreas to the microbiome, Tracy connects the dots in a way that’s practical and actionable for real-world clinical practice. She also shares key tools that can support earlier intervention, from smarter lab assessments to supplements like inositol and berberine.
This episode is packed with clinical insights and reminders that prevention starts long before blood sugar goes up, and that patients like Jane are counting on us to see what others miss.

| 01 Apr 2025 | EP06: Weight Loss through the Functional Medicine Lens | 01:08:26 | |
Weight gain isn’t always a result of overconsumption; it’s often the body’s natural response to imbalances that go undetected for years.
In this episode, Tracy Harrison breaks down four functional imbalances commonly at the root of overweight and obesity, starting with insulin resistance that often hides behind “normal” labs. How many patients are told they’re fine when their metabolism is anything but?
Tracy explains how stress, subclinical hypothyroidism, hormone disruption, and environmental toxins can all push the body to hold onto weight, even when someone is doing everything “right.” Could that daily fatigue or bloating be tied to something deeper?
This episode leaves practitioners with a challenge: stop chasing symptoms and start identifying the early signs of imbalance. Because when we address the real root causes, weight loss becomes a natural outcome, and patients finally feel seen, supported, and in control.

| 08 Apr 2025 | EP07: Root Causes of Disease in the Rx | 00:39:54 | |
Medications your patients trust most may be the very ones quietly driving their disease.
How often do we stop to question the long-term impact of the most common prescriptions? Tracy Harrison takes a close look at the unintended consequences of medications like beta blockers, diuretics, antibiotics, and high-dose vitamin D. These are drugs patients often take for years, sometimes decades, without realizing they could be fueling nutrient depletion, sleep disruption, gut dysfunction, or immune imbalance.
What happens when a beta blocker meant to lower blood pressure also suppresses melatonin and CoQ10? Or when a prescribed vitamin D dose leaves someone more magnesium-deficient than before? Tracy connects the clinical dots and urges practitioners to think beyond the prescription pad. She makes the case for a more nuanced approach, one that questions assumptions, looks for root causes, and sees medications as tools, not permanent solutions.
If you’ve ever wondered why a patient plateaus despite doing “everything right,” this episode offers perspective that could shift your clinical lens.

| 01 Apr 2025 | EP02: What IS Functional Medicine? | 00:16:23 | |
Functional medicine rejects symptom-chasing and asks a better question: why did the body stop working the way it’s designed to?
In this episode, Tracy Harrison explains what functional medicine really is through the lens of systems engineering. What if we approached the human body like a complex system, where every piece plays a role in either promoting health or driving dysfunction?
Using the image of a bonsai tree, Tracy illustrates how we miss the bigger picture when we focus only on the problem we can see. She then takes it a step further with three real-world examples of people who all have hypertension, but for completely different reasons. One person is dealing with blood sugar issues. Another is struggling with nutrient metabolism. A third is unknowingly affected by toxic exposure from decades ago.
So how do we help someone heal if we don’t first understand why they’re sick? This episode is an invitation to think differently. It challenges listeners to stop asking what to fix and start asking what’s interfering with the body’s ability to function. Through a systems engineering lens, Tracy shows how personalized assessment and targeted intervention can help restore balance without relying solely on symptom management.

| 01 Apr 2025 | EP01: Surprising Reasons They Don’t Get Better: Key Clinical Insights for Practitioners | 00:37:12 | |
Most cases of recurring IBS aren’t about the gut bugs. They’re about what’s upstream and overlooked.
Why do so many patients feel better at first, only to end up right back where they started? Tracy Harrison shares the real reasons IBS, type 2 diabetes, and other chronic conditions often come roaring back. She highlights two patterns that get missed far too often: maldigestion caused by low pancreatic enzyme output (which is closely tied to blood sugar issues) and sluggish gut motility linked to subclinical hypothyroidism, vagus nerve dysfunction, or past trauma.
Tracy also breaks down how poor sleep and internal stress quietly derail healing, even when a patient’s lifestyle looks “healthy” from the outside. Is someone really sleeping well, or are they just used to feeling tired? Is their blood sugar problem coming from diet, or from the constant background noise of stress?
Tracy connects the dots between oral health, immune dysfunction, and metabolic disease, showing how inflammation in the mouth can ripple through the whole system. She explains why high-dose vitamin D can backfire, how common medications like ibuprofen or PPIs might be sabotaging progress, and what to watch for when a patient’s improvement stalls without a clear reason.
At the heart of it all is a question every practitioner needs to ask: Am I offering too much, too fast? Tracy reminds us that real change comes from partnership, not overwhelm. The smartest plan in the world won’t help if it leaves your patient behind.

| 01 Apr 2025 | EP04: GLP-1 Gotchas for Practitioners | 00:28:21 | |
GLP-1 medications are everywhere right now and for good reason. They suppress appetite, support weight loss, and help manage type 2 diabetes. But what happens when we overlook the ripple effects they can have on the body?
In this first episode of Functional Medicine for Real-World Impact, host Tracy Harrison walks through four clinical “gotchas” every practitioner should keep in mind when patients are using GLP-1 agonists. She starts with one of the most common and disruptive complaints: nausea. For many patients, it’s not just the medication. It’s an underlying issue like histamine overload, subclinical hypothyroidism, or nutrient insufficiency that makes the symptoms worse.
Tracy also raises a critical question: Are we giving GLP-1s to patients who are already insulin resistant... or already hyperinsulinemic? If so, we may be increasing their risk for hypoglycemia, emotional reactivity, and unintended shifts in body composition.
Then there’s the issue of gallbladder health. Slowed motility may reduce appetite, but it can also make existing hepatic biliary congestion worse, especially for those with fatty liver or metabolic disease. Are we screening for this before starting treatment?
This episode challenges practitioners to look closer, ask better questions, and avoid assuming that symptom reduction equals success. Medications can be helpful, but only when paired with a deeper clinical lens and a commitment to long-term, real-world health.
Episode Breakdown: 00:00 Understanding GLP-1 Medications 01:02 Nausea and Dysmotility 05:01 Histamine Overload 08:04 Hypothyroidism and Dysmotility 10:01 Vitamin B6 and Magnesium Deficiency 11:27 Malnutrition Risks 17:00 Hypoglycemia Concerns 20:41 Hepatic Biliary Congestion 25:10 Responsible Use and Dosage 27:00 Importance of Empowering Patients

| 15 Apr 2025 | EP08: “You Are What You Eat”? Think Again! | 00:28:13 | |
Most people assume that eating healthy food is enough. But the real issue is often not what’s on the plate. It’s whether the body can actually use it.
In this episode, Tracy Harrison questions the idea that nutrition starts and ends with food choices. She breaks down why so many patients fail to thrive despite eating well and how digestion quietly plays a much bigger role than we give it credit for.
Tracy walks through four patient groups that often struggle with maldigestion: those with acid reflux, diabetes, hypothyroidism, and chronic aches and pains. Could common medications like PPIs or NSAIDs be interfering with nutrient absorption? Could sluggish bile flow or low enzyme output be blocking access to critical micronutrients? These are the kinds of questions she urges practitioners to ask more often.
Along the way, she explains why foundational functions—stomach acid, bile, enzyme activity, brush border integrity—deserve just as much attention as the more complex topics in functional medicine. Because when those basics are overlooked, even the best nutrition plans can fall flat.
This is a call to shift your focus back to the basics and to recognize that restoring digestive function may be the most powerful clinical move you can make.

| 01 Apr 2025 | EP05: Gut-Brain-Chronic Pain Connections | 00:43:15 | |
Chronic pain isn’t just a nuisance. It’s often a gut-driven signal that something deeper is out of balance.
In this episode, Tracy Harrison takes a practical look at how gut health shapes our experience of pain. She questions the default approach of reaching for medications and instead encourages practitioners to ask: what’s really driving the discomfort? Pain isn’t random. It often points to deeper issues like inflammation, nutrient deficiencies, and microbial imbalances, all of which are rooted in the gut.
Tracy breaks down how over-the-counter drugs like NSAIDs can quietly erode the gut lining, interfere with nutrient absorption, and set off a chain reaction that worsens the very symptoms they’re meant to relieve. She also shares why it’s worth paying closer attention to factors like sleep apnea, chronic stress, and low-grade infections that keep the body in a state of physiological alarm, and make pain more intense.
The conversation turns toward the gut-brain connection, where neurotransmitters like serotonin and GABA play a powerful role in pain perception. What happens when dysbiosis disrupts their production? How do nutrient shortfalls, especially in B12, magnesium, and tryptophan, shift the nervous system’s response to pain?
For practitioners, this is a clear reminder: if you’re not looking at gut health, you may be missing the source of your patient’s pain. Tracy lays out the case for why functional medicine must go beyond managing symptoms to uncovering the systems at play. It starts in the gut, and it can change everything.

| 22 Apr 2025 | EP09: Supplements: Missteps and Best Practices | 01:00:43 | |
Most supplement mistakes happen when we forget to ask the simplest questions: Why this? Why now? And for how long?
In this episode, Tracy Harrison breaks down why even the most well-intentioned supplement plans can miss the mark. She explains the three core reasons to use supplements (relief, reversal, and maintenance), and how overlooking these distinctions can lead patients to stay on products long after they’ve served their purpose.
Tracy also unpacks the hidden consequences of common medications, like how statins and beta blockers drain CoQ10 or how birth control pills deplete vitamin B6, creating new issues that are often misunderstood or missed entirely. Are your patients feeling better because of what you recommended or despite it?
This episode is a call to slow down, think critically, and move beyond protocol checklists. Tracy shares practical ways to educate patients so they feel like partners, not bystanders, in their own care. If you’ve ever wondered how to improve outcomes without overcomplicating your practice, Tracy offers a smart, grounded place to start.
