Summary
A physical transformation doesn’t automatically change the story you’re living inside. You can lose the weight, change the labs, clear the symptoms, hit the goal… and still feel like the same OG version of yourself. In this solo episode, Erin is talking about the “neuroscience of reality” – how your brain uses old beliefs, past experiences, and predictive patterns to construct what you see, how you feel, and what you think is possible for you.
This episode is all about self-sabotage. Erin explains how the brain filters millions of pieces of information down to a tiny fraction of conscious awareness, and how understanding this can create a massive amount of compassion for yourself in the healing process.
P.S. The Manifest Your Health app was built to support this exact process! Join today.
In this episode:
- The question Erin asks when she looks at labs: what did this person have to sacrifice, silence, or over-function through to get here?
- Why healing can start to feel like a hamster wheel when you’re only working with one “fractal” of yourself
- How Erin’s eating disorder recovery and autoimmune diagnosis deepened her understanding of self-attack biology
- Why the 1970 kitten study explains “behavioral blindness” and how your brain can filter out parts of reality

| 0:00.0 | We don't just passively perceive the world. We actively generate it. |
| 0:06.6 | Perception is a process of informed guesswork. Perception, what you're perceiving, is the brain's best |
| 0:13.0 | guess at interpreting ambiguous sensory input. It's essentially a story our minds tell us. |
| 0:24.5 | And in order to tell that story, the brain uses prior expectations. It's called predictive processing. Your brain is a prediction machine. And it's constructing |
| 0:30.7 | your reality in the moment based on what has happened in the past. So no, you don't just observe reality. Your brain |
| 0:41.4 | is actively constructing it. It's building it based on those predictions. Welcome to the functional |
| 0:49.5 | nutrition podcast, spell it with a K, because we do things a little differently around here. |
| 0:53.8 | I'm your host, Erin Holt, and I've got 15 years of clinical experience as a functional |
| 0:57.6 | nutritionist and mindset coach, creating a new model that I call intuitive functional medicine, |
| 1:02.9 | where we combine root cause medicine with the innate intelligence of your body. |
| 1:07.4 | This is where science meets self-trust. Your body already knows how to heal and this show |
| 1:12.8 | is going to show you how. If you're looking for new ways of thinking about your health, be sure to |
| 1:17.3 | follow and share with a friend because you never know whose life you might change. |
| 1:22.6 | Hey out there. How we doing? Happy June. Listen, I have received so much wonderful feedback from the |
| 1:30.6 | past two conversations we've had here on the show, especially the one with Jessica Brown. |
| 1:35.8 | That was a doozy. I knew that talking about GLP ones would elicit some reactions and some feelings totally normal, |
| 1:47.9 | totally understandable. I just didn't anticipate how much positive feedback I would get, |
| 1:53.8 | where people are really appreciating these conversations. And so I just love you guys. |
| 1:59.4 | And for those of you who have DM me, thank you. It's been really great to see your response to this conversation. And I want to make it crystal clear that I do not think everyone should be on a GLP1. Hopefully last week's episode really emphasized that point. can be problematic they can cause a ruckus |
| 2:19.5 | with your physiology but they can be a tool in some people's tool bag and i think we just have to |
| 2:26.3 | look at all of these things as tools whether it's a supplement or breathwork or a pharmaceutical, their tools in the tool bag. |
| 2:38.0 | And I am all for giving people more tools, not taking them away, kind of my forever stance. |
