The gut is one of the most talked-about topics in health right now. But there’s also a lot of confusion. On this episode of the Dylan Gemelli podcast, Dr. Colleen Cutcliffe, Co-Founder & CEO of Pendulum, joins for a deep dive into the microbiome.
Dylan and Colleen dive into the questions people actually have: what matters most for your health, what’s real versus misleading, and how much the gut truly impacts the rest of the body.
Dylan Gemelli is known for his direct, performance-driven approach to health. His audience comes for simple explanations, real-world applications, and honest answers.
If you’ve heard that gut health matters but haven’t fully understood why, this is the kind of conversation that connects the dots.

What this episode covers
If you watch the full episode, you’ll notice this isn’t a linear, scripted conversation. It moves the way real curiosity does by starting broad and getting more specific as more questions come up.
Here’s a closer look at what Dylan and Dr. Cutcliffe unpack.
Starting with the fundamentals: what actually matters for health?
One of the first questions Dylan asks is simple, but important:
If you had to rank what matters most for health, where does the gut fit?
Dr. Cutcliffe’s answer is nuanced. The gut isn’t the only system that matters, but it’s one of the few that can influence all the others. Through the microbiome, the gut connects to digestion, metabolism, brain function and even immune response.
So while you can live with a gut that’s not working optimally, it may quietly affect how everything else performs.
Breaking down misinformation in gut health
There’s a lot of advice out there that sounds right but lacks substance.
Part of the goal of this episode is to separate what’s actually supported by science from what’s oversimplified or misleading. That shows up in how they talk about probiotics, diet trends, and even common assumptions like “all bacteria are bad.”
Adding more nuance to misinformation about the gut is the limited focus that traditional medical training has on emerging topics like the microbiome. It’s a relatively new area of science, and many healthcare providers simply weren’t taught how to evaluate or treat it.
That doesn’t mean they’re doing anything wrong. It just reflects how quickly this field is evolving. But it does mean that if you’re dealing with symptoms tied to the gut, you may need to look beyond standard approaches to fully understand what’s going on.
Your microbiome as a fingerprint
Dylan and Colleen introduce a powerful idea: Your microbiome is unique to you.
Even if two people have similar types of bacteria, the overall composition—the balance, the functions, the interactions—is different.
Your individual microbiome fingerprint reflects factors like your genetics, your environment, your diet and your habits. That’s why there’s no one-size-fits-all solution. What works for one person may not work the same way for someone else.
The everyday habits that shape your gut
A big portion of the episode focuses on practical, real-world recommendations.
Some of the biggest takeaways:
-
Antibiotics have one of the strongest effects, wiping out both good and bad bacteria
-
Diet plays a constant role, since you’re feeding your microbiome with every meal
-
Sleep and circadian rhythm are closely tied to gut health
-
Overtraining, stress, and travel can all shift the microbiome
It’s not just one thing. It’s the accumulation of small, repeated inputs over time.
The thread that runs through the entire conversation
If there’s one theme that ties the episode together, it’s this: Your microbiome is dynamic.
It changes based on what you do, it responds to your environment, and it can improve over time.
You don’t need a perfect routine. You don’t need to overhaul everything overnight. But understanding how your gut works and making small, consistent changes can have a real impact on how you feel.
