Summary
What if your gut-brain axis isn’t just a “cute concept”… but the thing running the show?
Erin is giving you the FULL class from last week’s Funk’tional Nutrition Academy Open House, breaking down how stress, subconscious patterns, and nervous system signaling directly shape digestion. This one’s for my practitioners, but honestly, if your gut isn’t improving, you’re going to want to hear this too.
You’ll understand how perception shapes digestion, why healing requires both gut work and nervous system work, and how to start interrupting the loop that keeps symptoms stuck.
In this episode:
- The role of subconscious patterning in shaping your symptom experience, and how those patterns can be changed
- How neuroplasticity becomes a tool for gut healing, and why your brain is not stuck in old patterns
- How shifting out of a constant “on guard” state can restore motility, enzyme output, and real digestive function
- The “prediction loop” your brain runs after repeated gut symptoms, and how it primes your body to react
- How your brain can misinterpret normal gut sensations as “dangerous”, through visceral hypersensitivity

| 0:00.0 | All day, every day, your nervous system is scanning your environment, both internally, what's going |
| 0:07.1 | on inside and externally. So we have exteroception, which is taking in cues from our outside world, |
| 0:14.7 | external stimulus. We have interoception, which is listening and being aware of the cues coming |
| 0:19.9 | from inside our body. And then we have |
| 0:22.2 | proprioception, which is basically like where we are in space. So your brain is constantly taking in |
| 0:28.8 | and integrating all three of these things. And it acts like a filter. So we have stimulus that |
| 0:35.5 | comes in. The brain has to categorize it. It has to define it. |
| 0:39.6 | It has to say, what does this mean? What category do I put this in? And then based on how it tags it, |
| 0:45.9 | how it determines what the meaning is, it signals to the rest of the body. Welcome to the |
| 0:52.2 | Functional Nutrition Podcast. Spell it with a K, because we do things |
| 0:55.0 | a little differently around here. I'm your host, Erin Holt, and I've got 15 years of clinical experience |
| 0:59.9 | as a functional nutritionist and mindset coach, creating a new model that I call intuitive |
| 1:04.6 | functional medicine, where we combine root cause medicine with the innate intelligence of your body. |
| 1:10.3 | This is where science meets self-trust. |
| 1:13.0 | Your body already knows how to heal and this show is going to show you how. If you're looking |
| 1:18.1 | for new ways of thinking about your health, be sure to follow and share with a friend because you |
| 1:22.3 | never know whose life you might change. |
| 1:25.4 | Hey, friends. Today is all about the gut brain access, specifically how stress perception and the |
| 1:30.9 | subconscious shape, digestive health. |
| 1:33.6 | We've got a fully packed episode for you today. |
| 1:36.9 | There's a lot, a lot, a lot of stuff in here. |
| 1:39.1 | You guys love last week so much that we decided to release another class from our FNA open house. |
