Erin is soaking up the Maine sun for a couple of weeks, so today we’re pulling a biggie out of the vault: an episode all about inflammation hunting.

Yes, diet and lifestyle matter big time. But sometimes someone is doing “all the right things,” eating well, moving their body, taking care of themselves… and the math still isn’t mathing.

Erin and TFN lead practitioner Rachel Heintz, MS, RDN, IFMCP, FHP-C, are breaking down what inflammation actually is, what symptoms and labs can raise red flags, and how they use deeper testing to figure out what’s keeping the immune system irritated and overwhelmed.

They also get into gut health, blood sugar, gluten sensitivity, low beneficial bacteria, secretory IgA, calprotectin, cortisol, melatonin, mold, heavy metals, and why sometimes the answer is not a protocol.

P.S. Applications are officially open for the Fall 2026 cohort of The Funk’tional Nutrition Academy, Erin’s 14-month practitioner training and mentorship. Apply now!

1. The blood work, GI-MAP, DUTCH, and OAT clues Erin and Rachel look at when inflammation is suspected
2. Why Erin says the “basics” are not basic, and why skipping them can keep people stuck at 20% better
3. The secretory IgA cycle that keeps people catching everything that goes around
4. Why eating more (not fasting harder!) was the missing piece for one client’s blood sugar, gut, and weight
5. The chronic UTI case study that shows why functional medicine is really about quality of life

What does it mean to embody your magic? In this episode, Erin talks to psychic channel, medium, spiritual guide, teacher, and author Aycee Brown to get into allllll the tools: astrology, numerology, human design, mediumship, metaphysics, manifestation, intuition, and the ways they can help you come back to yourself.

Aycee shares what human design helped her understand about herself as a projector, the difference between intuition and anxiety, and why discernment is going to matter more than ever in a world full of misinformation, clickbait, and people trying to hijack your brain.

1. What coffee shops, neighborhood dogs, and daily interactions can teach you about your magic
2. How tools like astrology, numerology, and human design can help you come back to yourself
3. The “bricks” that block your intuitive gifts, and why healing helps you access what was already there
4. Why reading a physical book might be one of the most underrated spiritual practices right now

After working with hundreds of 1:1 clients (and thousands across all of TFN's offerings), Erin has noticed some VERY predictable patterns in the healing process. And spoiler alert: healing rarely looks the way people think it's going to!

What happens during "the dip" and why do so many people feel like quitting around months 3 and 4? Erin gets into the expectation vs. reality gap that keeps people stuck on the hamster wheel of healing, the nervous system patterns that surface when things start changing, and the difference between feeling “good enough” and feeling like a completely different human.

If you're in a season where you're questioning your progress, doubting your body, or wondering if anything is ever going to work for you, this might be the episode you need most.

1. The dopamine hits that come from finally getting answers, labs, and a plan
2. Why Erin doesn't want you to depend on practitioners, protocols, or wellness influencers forever
3. The surprising reason clients start pushing their boundaries around months 7 and 8
4. Why feeling amazing, overdoing it, and crashing can actually be a sign that your world is expanding (!)
5. The importance of embodiment and why it’s a part of Erin’s C.A.R.E method

PCOS just got a glow up. This wildly misunderstood condition affects 1 in 8 women and 170 million women worldwide, and has officially been renamed PMOS: Polyendocrine Metabolic Ovarian Syndrome. In this episode, Erin is joined by TFN lead practitioner Rachel Heintz, MS, RDN, IFMCP, FHP-C, to talk about why this name change matters.

Rachel breaks down why the old PCOS label created so much confusion, and how PMOS can impact metabolism, blood sugar, cardiovascular health, skin, fertility, mental health, and more.

This is a whole-human conversation about a whole-body condition, because women are more than “just hormones walking around,” and this condition was never just about the ovaries.

1. Why PCOS was renamed PMOS, and how the new name reflects what’s actually happening in the body
2. The four PMOS archetypes Rachel sees most often: insulin-resistant, inflammatory, adrenal, and post-pill
3. How perfume, dryer sheets, and what’s under your kitchen sink can all matter for endocrine health
4. The fertility case study that had surprisingly little to do with the ovaries themselves

Sometimes you go looking for that one cutting-edge clinical pearl, and what you actually get is a full body reminder of why this work matters.

After taking the TFN team to the IFM conference in San Diego, Erin is sharing her honest reflections and biggest takeaways, including the conversations that made her feel like functional medicine is moving in a hopeful direction.

She gets into GLP-1 tapering, preconception care, women’s health, emotional regulation, practitioner burnout, and community as medicine. Plus, emotional wellness is FINALLY entering the chat!

P.S. Applications for the fall cohort of the Functional Nutrition Academy open soon! Join the waitlist.

1. Why the IFM conference reinvigorated Erin, even if the curriculum wasn’t what she expected
2. Seeing Dr. Terry Wahls in person, and why she was an OG expander for Erin’s autoimmune healing
3. How GLP-1s may not have to be “forever drugs” when tapering and satiety signals are used skillfully
4. The “health-to-isolation pipeline” and why healing in a cocoon is powerful… until it starts making your life smaller

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.

1. The question Erin asks when she looks at labs: what did this person have to sacrifice, silence, or over-function through to get here?
2. Why healing can start to feel like a hamster wheel when you’re only working with one “fractal” of yourself
3. How Erin’s eating disorder recovery and autoimmune diagnosis deepened her understanding of self-attack biology
4. Why the 1970 kitten study explains “behavioral blindness” and how your brain can filter out parts of reality

Ozempic culture is officially here, and after last week’s GLP-1 episode with Jessica Brown, Erin has more to say.

This time, she’s getting into the side effects practitioners are seeing and the “microdosing” marketing language that’s gotten wildly out of hand. Erin talks about the difference between using GLP-1s skillfully vs. going a little willy nilly with telehealth prescriptions, and people chasing quick weight loss without understanding what’s happening physiologically.

This is an important “part 2” conversation around why these medications can be an incredibly effective tool… while still requiring education, self-awareness, support, and a whole lot more nuance than the internet shows.

In this episode:

• Why Erin thinks we’re wildly underprepared to use GLP-1s correctly
• What “Ozempic culture” gets right… and where the conversation completely misses the mark
• “Food as skinny vs. food as fuel” and why micronutrients matter more than ever if you’re on a GLP-1
• How Erin’s client used tirzepatide without jumping to higher and higher doses
• The GLP-1 side effects Erin is seeing most often, including SIBO flares and reflux

Oh boy… Erin is FINALLY having an unfiltered GLP-1 conversation with the person she wanted to have it with first: Jessica Brown, a clinical nutritionist, Stanford-trained teacher, founder of the GLP-1 Nutrition Academy, author of The Loving Diet and Beyond the Shot, and one of Erin’s longtime mentors.

This is not a “GLP-1s are good” or “GLP-1s are bad” episode. It’s the difference between semaglutide and tirzepatide, what “microdosing” means, and why these medications are being studied for so much more than weight loss. Erin and Jessica also talk about identity, worthiness, body positivity, and the role of social media influencers when it comes to GLP-1s.

• Why Jessica believes GLP-1s could become one of the biggest disruptions in modern healthcare
• Erin’s thoughts on influencers, GLP-1s, and the pressure to maintain a certain identity online
• How AI is impacting lab analysis and why consciousness matters (it’s AI-proof!)
• Why GLP-1s are not powerful enough to change your beliefs about worthiness and identity
• What practitioners NEED to know as GLP-1s and metabolic health reshape the future of functional medicine

If you feel like you’ve done EVERYTHING to support your fertility journey, cleaned up your diet, worked on your gut health, taken all the supplements, tracked alllll the things and you’re still not pregnant… this episode will speak to you.

Erin and TFN Practitioner Nicole Antes are walking through a fertility case study for a client who came to them after trying to conceive for a year with a 16+ supplement routine that wasn’t necessarily supporting her body in the way it needed.

Together, they get into the downstream effects of overly aggressive gut protocols, hyper-fixation, nervous system regulation, and how easy it can be for TTC to feel like a full-time job. There were some subtle shifts that helped this client finally move the needle and get a positive pregnancy test!

In this episode:

• The role of methylation, mitochondrial health, and antioxidant support in egg quality and embryo development
• Why herbal antimicrobials can sometimes “kill the good guys” after aggressive gut protocols
• How Dad’s health influences a healthy fertility journey, and how sperm quality can shift within 3-6 months
• Why taking a month off from tracking could be the most supportive nervous system shift
• The surprising thing this client did before finally getting a positive pregnancy test

There’s a version of functional medicine that works, and then there’s the version that leaves people with a stack of labs, a cabinet full of supplements, and a whole lot of confusion. In this conversation, Erin is joining holistic nutritionist Ali Shapiro on the Truce with Food podcast to get candid about the difference, what she’s seeing in her own practice, and why things have gotten a little “wonky” in the wellness space.

Erin gets into the trenches of how her work has shifted, why she’s no longer looking at the physical body in isolation, and what happens when you bring the nervous system, your patterns, and your lived experience into the room.

P.S. The special $49/month founder’s rate for the Manifest Your Health membership ends THIS week!

1. Erin’s definition of intuitive functional medicine, and why it’s not about choosing between the body, mind, or nervous system
2. How to self-source and trust your own body vs. outsourcing to experts
3. Why more data (labs, trackers, testing) isn’t always better, and how it can disconnect you from your body
4. The “and both” approach to health and why this is where real transformation happens
5. What it looks like to work with a practitioner who co-pilots with you
