Most people chalk chronic bloating, food reactions, and “IBS” up to diet alone—yet Lyme disease can be the missing link. As the “Great Mimicker,” Lyme can dysregulate the nervous system, disrupt bile flow, open the gut barrier, and trigger downstream inflammation that looks like everyday digestive issues.

In this Gut Reset Summit interview, Dr. John Dempster sits down with Dr. Jaban Moore to unpack the Lyme–gut connection: why infections and co-infections fuel food sensitivities, how vagus nerve stress derails digestion, smarter ways to test beyond the basics, and a strategic, root-cause roadmap for real recovery.

Could investigating Lyme be the turning point in your chronic gut symptoms?

I thought I was doing everything right.
I swapped soda for almond milk lattes. Ditched sugar. Embraced oatmeal and sprouted grain bread.
But I still felt bloated, sluggish, and stuck.

Turns out, some of the “cleanest” foods in my kitchen were silently wrecking my metabolism.

That’s the thing:
Not all healthy foods are healthy for you.

Even oatmeal, agave syrup, almond milk, and “protein” bars can spike insulin, disrupt gut health, or inflame your thyroid - especially if your system’s already overwhelmed.

This isn’t about restriction. It’s about awareness. Because when your metabolism is inflamed or your hormones are off, even the best diets backfire.

In my latest blog, I’m breaking down the top 5 foods most people eat daily that unknowingly sabotage their progress - and how to uncover what your body truly needs to thrive.

I was eating cleaner than ever.
Working out more. Cutting sugar, processed foods, and late-night snacking.
But the scale wouldn’t budge, and my energy felt worse than before.

Here’s what I didn’t realize:
Chronic stress was hijacking my metabolism.

When cortisol stays high, your body shifts into survival mode.
Blood sugar rises, insulin resistance builds, thyroid slows, gut becomes inflamed, sleep gets disrupted - and your body holds onto fat as protection.

No diet or workout could fix it until I addressed the real issue: stress.

In my latest blog, I share how stress blocks fat burning, why traditional diets fail when your cortisol is chaotic, and what it really takes to reset your metabolism from the inside out.

Most people think leaky gut is something you either “have” or “don’t” - but intestinal permeability can switch on and off, and when it stays hyperpermeable, it can ripple far beyond digestion into inflammation, brain fog, and even autoimmunity.

In this Gut Reset Summit interview, Dr. John Dempster sits down with Dr. Peter Kan - board-certified in integrative and functional medicine and creator of NeuroMetabolic Integration - to demystify leaky gut. They unpack real root causes (processed foods and gluten, dysbiosis, toxins like glyphosate, blood sugar and thyroid imbalances, chronic stress), smarter testing (zonulin/occludin antibodies, LPS), and practical, data-driven strategies to restore barrier integrity and resilience.

Could healing your gut lining be the missing link in your chronic symptoms?

I used to wonder why I felt exhausted all day, only to be wide awake at night.

My mind would race at 10pm, and at 3am I’d be staring at the ceiling - heart pounding, thoughts buzzing.
Then mornings came, and I’d feel groggy, irritable, and desperate for coffee just to function.

Turns out, it wasn’t just stress.
My cortisol rhythm was in chaos.

Cortisol isn’t bad. It’s your energy hormone, meant to rise in the morning and taper at night. But when chronic stress, blood sugar swings, inflammation, poor sleep, or overtraining flip this rhythm, you’re left tired-but-wired - trapped in survival mode.

In my latest blog, I share why this cortisol chaos sabotages your sleep, metabolism, hormones, and gut - and what it really takes to restore your natural rhythm and reclaim steady energy again.

I thought I was doing everything right.
Swapped white bread for sprouted grain. Added leafy greens, quinoa, wild salmon, almond butter.
But the scale didn’t budge. In fact, it crept up.

Here’s what I didn’t realize:
Weight gain isn’t just about calories.
If your gut is inflamed, your blood sugar unstable, or your hormones out of sync, even the healthiest foods can work against you.

In my latest blog, I share why your “perfect” diet might be fueling hidden inflammation, bloating, and metabolic sluggishness - and what your body is really trying to tell you.

Most parents focus on their child’s physical fitness and education—yet the pillar that’s often missing is mental fitness. Without it, stress and anxiety can silently disrupt gut function and weaken resilience.

In interview, Dr. John Dempster sits down with Natalie von Teichman, founder of miindfully and creator of TATE, the first multisensory meditation stuffy for kids. Together they explore how teaching children mindfulness and breathwork builds mental agility, stimulates the vagus nerve, and lays the foundation for a healthier gut and immune system.

Could strengthening your child’s mind be the key to protecting their gut health?

I used to think detoxing was the answer.
Juice cleanses, herbal flushes, fasting resets.
But instead of feeling better, I felt worse - more bloated, tired, and foggy than before.

Here’s what I learned:
Detoxing without first healing your gut is like pouring buckets of water into a clogged sink.
Nothing flows out. It just overflows, making a bigger mess.

Your gut is your drainage pathway. If it’s inflamed, leaky, or imbalanced, toxins just recirculate, burdening your liver and triggering more inflammation.

In my latest blog, I share why gut repair is the foundation of true detoxification - and how rebuilding your gut lining, microbiome, and digestive strength unlocks the energy, clarity, and weight loss you’ve been seeking.

I cleaned up my diet. Added workouts. Tried to sleep better.
But the belly fat? It stayed.

What I didn’t realize is that my body wasn’t fighting fat.
It was fighting stress.

Chronic stress isn’t just mental. Biologically, it raises cortisol, slows your thyroid, inflames your gut, disrupts sleep, and drives cravings - all while telling your body to store fat as protection.

In my latest blog, I share why this stress-weight gain cycle keeps so many people stuck, why it’s not about willpower, and what it really takes to break free.

Childhood gut health is under threat, as rising autoimmunity, allergies, anxiety, and ADHD are no longer rare but common.

In this Gut Reset Summit interview, Dr. John Dempster speaks with Dr. Elisa Song, an integrative pediatrician, about why healing leaky gut in children is crucial for lifelong immunity, mental health, and development. From the first years of microbiome formation to the role of diet, antibiotics, and even the vagus nerve, the conversation reveals how the gut is shaping our kids’ future health in ways we can no longer ignore.

Could your child’s gut be the missing link to their growth and resilience?
