Move over, protein. There’s a new wellness obsession in town and her name is FIBER.

In this episode, Erin talks about the rising trend of “fibermaxxing” and why it’s more than just a catchy Gen Z trend. You’ll learn how fiber fuels your gut microbiome, supports short-chain fatty acid production, and impacts everything from hormone balance to inflammation.

But it’s not as simple as loading up overnight. Erin explains the distinct differences between soluble, insoluble, and resistant starch fibers, why variety is key for a resilient, diverse microbiome, and how to add fiber-rich foods and functional fiber supplements without triggering digestive distress.

Start slow, stay consistent, and prepare to reap the benefits!

• Why “fibermaxxing” is more than just a TikTok trend, and how to use it to actually improve gut health
• The hidden ways your gut microbiome shapes immunity, mood, hormone balance, and even your detox capacity
• How different types of fiber, like soluble, insoluble, and resistant starch, work alongside polyphenols to feed good bacteria
• Erin’s favorite strategies for upping your fiber game without the gas, bloating, or IBS flare-ups
• Why eating 30-40 different plants each week is the simplest path to a stronger microbiome

Your thyroid influences nearly EVERY system in your body, from metabolism and digestion to mood, fertility, and energy, and in this episode, Erin is sharing how to support your thyroid health with deep nutrition.

You’ll learn why blood sugar regulation is the foundation of hormone health, and how thyroid-supportive nutrients like selenium, magnesium, and zinc can help optimize function and reduce risk for common imbalances.

Erin also explores the nuances of “anti-nutrients” like iodine and goitrogens, especially for those managing Hashimoto’s. She outlines practical food choices (think colorful veggies!), supplementation tips, and key labs to keep an eye on, so you can feel more confident in supporting your thyroid health starting today.

• Why unstable blood sugar makes thyroid medication and supplements less effective
• Must-have foods and nutrients to rotate for thyroid support, including selenium, magnesium, and zinc
• The surprising truth about cruciferous veggies like broccoli and cauliflower - and how you can enjoy them without sabotaging iodine uptake
• When iodine helps and when it can trigger Hashimoto’s flare-ups
• The safe supplements nearly everyone can use vs. those that require lab testing first

Is it really perimenopause, or just stress, habits, and thyroid shifts at play? In this episode, Erin is debriefing her 6-month thyroid and hormone protocol experiment.

After noticing changes in mood, cycle irregularities, fatigue, and PMS, she decided to run a full panel of labs, including thyroid markers, sex hormones, a DUTCH test, and a GI-MAP stool test.

Erin breaks down exactly what her labs revealed, the protocols she implemented, and the results she’s experienced that have shifted her energy, mood, and cycles.

Her biggest takeaway? Protocols aren’t one-size-fits-all. With the right testing, lifestyle shifts, and targeted support, you can move from feeling “off” to feeling like yourself again.

In this episode:

• Why a “normal” TSH doesn’t always mean your thyroid is working optimally, plus the key marker Erin found functionally low
• Erin’s favorite supplements to support thyroid conversion, adrenal resilience, and hormone balance
• Why lifestyle habits, stress, and resiliency matter just as much as labs when addressing hormone health
• The surprising supplement Erin stopped and what she replaced it with that made a “night and day” difference
• Why so many people assume “hormone protocol” automatically means HRT – that’s not always the case!

Forget botox and retinol. Peptides are changing the game in skincare longevity, and for the past six months, Erin’s best-kept skincare secret has been a science-backed line that doesn’t just improve how skin looks. It actually helps reverse its biological age!

In this episode, we’re uncovering ALL the groundbreaking research on peptides with OneSkin co-founder, scientist, and healthy aging advocate, Carolina Reis Oliveira, PhD.

Instead of quick fixes or invasive treatments, Carolina explains how their proprietary OS-1 peptide targets “zombie cells” (senescent cells) that accelerate skin aging and inflammation, helping restore healthier, more resilient skin.

From reversing fine lines and wrinkles to supporting scalp and hair vitality, this episode applies a functional approach to skincare to help you look and feel better at every age.

Getting your labs done can feel empowering. FINALLY, you can have hard data about what’s going on inside your body.

But want to know the truth? Those results alone rarely create transformation. In this episode, Erin is talking all about Function Health, a direct-to-consumer lab testing company founded by Dr. Mark Hyman. She breaks down exactly what you get, and why it’s valuable if you’re serious about improving your health.

There can be major advantages of this kind of testing (think comprehensive biomarker panels, functional medicine interpretation, and the ability to track trends over time), but even the best labs won’t move the needle without a plan for integration.

Tune in to learn about Erin’s “Information + Integration = Transformation” framework, along with real-world client examples to show how coaching, mindset shifts, and consistent action are the true game changers.

• The #1 misconception about comprehensive lab testing
• How Function Health’s biomarker panels stack up against traditional testing and why Erin thinks it’s a smart idea for certain people
• The key difference between conventional reference ranges and functional medicine’s optimal ranges (and why this matters for early intervention!)
• Erin’s “Information + Integration = Transformation” framework for turning knowledge into lasting behavior change
• How Erin’s client shifted from red flags in their blood work to coaching and lifestyle shifts to spark change

It’s time to uncover what's ACTUALLY going on in your gut! Are you stuck in the cycle of treating SIBO over and over, only to have your symptoms return? Today, Erin and Rachel Heintz, MS, RDN, are revealing the most common reasons that keep people stuck in the SIBO loop, including why standard protocols and restrictive diets often miss the mark, and the deeper, more nuanced reasons SIBO recurs.

You'll learn what your stool test might be trying to tell you, how stress and low stomach acid sabotage gut healing, and the critical roles bile flow, mineral status, and even meal timing play in your recovery.

Whether you're dealing with persistent bloating, IBS-like symptoms, or have been told you just need “another round of antibiotics”, this conversation will help you finally move forward.

In this episode:

• Why low stomach acid and bile flow are two of the biggest root causes of recurring SIBO
• Grazing all day might be sabotaging your gut's natural cleaning system (the Migrating Motor Complex)
• The surprising role of serotonin and mineral imbalances in gut motility and chronic constipation
• What your breath test and stool test can and can’t reveal about your gut health
• Why SIBO won't truly resolve unless you address large intestine dysbiosis, immune function, and structural issues like valve dysfunction or surgical adhesions
