Summary
So many people bounce between specialists, run every lab under the sun, and still feel stuck in the same symptom loop. What if the problem isn’t missing data, but the way we’re looking at the body in the first place?
In this episode, Erin is giving you an exclusive sneak peek inside the Funk’tional Nutrition Academy Open House, where she breaks down her model of intuitive functional medicine.
Erin explains why healing requires more than labs and protocols, how nervous system patterns shape our symptoms, and why self-trust might be one of the most overlooked pieces of root cause care.
In this episode:
- Why chronic illness is often a breakdown in communication between body systems instead of a single root cause
- How practitioners can help clients rebuild self-trust and reconnect with their body’s healing intelligence
- The surprising role of interoception and how trauma, stress, and conditioning can distort how we interpret signals
- Erin’s framework for combining lab data, nervous system work, and intuition in root cause care

| 0:00.0 | This is one of the chief problems that we're seeing with healthcare. |
| 0:03.3 | We have different specialists who focus on one area, rather than understanding that disease is really a loss of communication and a loss of interplay between all areas of the body. |
| 0:14.6 | So there's just a huge lack of understanding of how these interrelationships work. |
| 0:20.1 | And that's why it can be so hard for our clients |
| 0:22.2 | to break out of chronic conditions, chronic illness, or chronic symptoms. Welcome to the functional |
| 0:28.7 | nutrition podcast, spell it with a K, because we do things a little differently around here. |
| 0:33.1 | I'm your host, Erin Holt, and I've got 15 years of clinical experience as a functional nutritionist |
| 0:37.4 | and mindset coach, creating a new model that I call intuitive functional medicine, where we combine |
| 0:42.7 | root cause medicine with the innate intelligence of your body. This is where science meets self-trust. |
| 0:49.3 | Your body already knows how to heal, and this show is going to show you how. |
| 0:53.7 | If you're looking for new ways of |
| 0:55.2 | thinking about your health, be sure to follow and share with a friend because you never know |
| 0:59.1 | whose life you might change. Hi, friends. Today we are going beyond systems biology and we're talking |
| 1:07.2 | about the missing link in functional medicine. This is actually a live class that I taught |
| 1:12.3 | just last week for our FNA, the Functional Nutrition Academy, Open House. It's the first time |
| 1:18.1 | that we've done this. It's still going on. It's two full weeks of opening our doors to live |
| 1:23.3 | classes so practitioners can come in and get a feel for the school. And this class, like I said, |
| 1:29.4 | we taught last week. And it got some really, really great feedback. So I figured I would release it |
| 1:34.6 | here as a podcast episode. We did have more of a Q&A discussion at the end of the class. We cut |
| 1:40.8 | that part out. But the whole class is here for you to listen to. Just as a reminder, |
| 1:46.2 | we are currently in FNA enrollment. We open enrollment twice a year. And we are keeping enrollment |
| 1:52.5 | open through the end of the month or until all seats are filled. So if you haven't filled out |
