Together they cover what’s happening to our hormones as we age and why symptoms look so different from woman to woman. Karen explains what’s most misunderstood about HRT, what to consider with estrogen, progesterone, and testosterone, including delivery forms and the lab markers she looks at, and how and when to testThey also get into whether to go by labs or by how you feel, why timing matters, and how to advocate for yourself with a practitioner.

    The Real Min. Effective Dose for Strength Training with Steph Gaudreau

    Send us Fan Mail We've gotten the memo: building and preserving muscle matters for women, at every age, for reasons that go way beyond aesthetics. But if lifting isn't already part of your routine, where do you actually start — and how do you make it stick when life is already full?  This week, I sat down with Steph Gaudreau, a certified strength and nutrition coach who's spent over a decade helping busy, athletic women over 40 train smarter, not harder. We cover the real minimum effective dose for strength training (it's less than you think), why combining exercises for "efficiency" usually means underloading your legs, how to build strength through tempo and range of motion in addition to adding weight, and why it's genuinely never too late to start. We also dig into fueling lifting sessions differently than endurance training, and why so many women are still afraid of carbs.  Resources from this episode can be found at: https://www.fuelwitherin.com/podcast/v/episode-36-the-real-minimum-effective-dose-for-strength-training-with-steph-gaudreau  CONNECT WITH STEPH Instagram profile | steph_gaudreau Website | https://www.stephgaudreau.com Fuel Your Strength Podcast | https://www.stephgaudreau.com/fuel-your-strength-podcast FUEL YOUR PERFORMANCE Momentous is my go-to for high-quality, science-backed supplements → Offer: Use code FuelWithErin for 14% off one-time purchase and 35% off first-time subscriptions Shop here: https://crrnt.app/MOME/1KeXpK4v  LETS CONNECT: Instagram | @fuel.with.erin Youtube | @Fuelwitherin Spotify | Apple Podcasts  Submit a Story | https://fuelwitherin.com ========== Disclaimer: The information provided in this podcast and its show notes is for informational and educational purposes only.

    The Blood Sugar Masterclass Every Woman Over 40 Needs with Nutritionist Kayla Girgen

    Send us Fan Mail You could be doing everything "right" and still riding a blood sugar roller coaster, with cravings, crashes, and mood swings driven by stress and not just what you eat, but how you pair your macros together. In this episode, I sit down with Kayla Girgen, a functional dietitian and certified personal trainer, and founder of Nutrition with Kayla, for a full blood sugar masterclass.  Kayla breaks down what a continuous glucose monitor (CGM) actually measures, why insulin resistance works like ‘sticky keys in a lock,’ and how to read your own data without a science degree. Kayle and I look at my own CGM history, to dig into how to read monitors and why you should keep your blood glucose levels looking like rolling hills vs peaks and valleys. The conversation also pivots to rucking—the simple, weighted-walk practice Kayla calls her "nature's Prozac", where Kayla breaks down the real benefits and exactly how to start with gear you already own.  Resources from this episode can be found at: https://www.fuelwitherin.com/podcast/v/episode-35-the-blood-sugar-masterclass-every-woman-over-40-needs-with-nutritionist-kayla-girgen  CONNECT WITH KAYLA Instagram profile | @kaylagirgenrd Website | kaylagirgen.com Free CGM guide: https://go.kaylagirgenrd.com/cgm-guide  Ruck Fit on Amazon: https://amzn.to/4hhG0pl FUEL YOUR PERFORMANCE Momentous is my go-to for high-quality, science-backed supplements → Offer: Use code FuelWithErin for 14% off one-time purchase and 35% off first-time subscriptions Shop here: https://crrnt.app/MOME/1KeXpK4v  LETS CONNECT: Instagram | @fuel.with.erin Youtube | @Fuelwitherin Submit a Story | https://fuelwitherin.com ========== Disclaimer: The information provided in this podcast and its show notes is for informational and educational purposes only.

    All-or-Nothing Eating Is Keeping You Stuck: The 80/20 Nutrition Fix That Actually Sticks with Francesca Scerbo

    Send us Fan Mail If you’re anything like me, you thrive on structure, control, and routine—until that same drive turns your nutrition into a rigid checklist that works against you. In this episode, nutrition coach and clinical expert Francesca Scerbo joins me to break down why rigid, all-or-nothing eating holds women back, and how adopting an 80/20 mindset with a few key elements in mind creates lasting results. Francesca—who overcame a teenage battle with anorexia before founding her company, Balanced Nutrition—explains why one-size-fits-all nutrition rules fail women and what a truly personalized, adaptive approach looks like. She busts common nutrition myths, revealing why food sensitivity tests can mislead you, how to hit your fiber targets without relying on supplements, the hidden hydration mistake that mimics hunger, and the label-reading trick to bypass ‘protein-washed’ marketing. This episode dives into specific, no-fluff tools Francesca and Erin use to stop guessing and start nourishing your body with confidence.

    Why Your Workouts Stopped Working (And What Actually Fixes It) with Dr. Carla DiGirolamo

    Send us Fan Mail You did the workout, you ate "clean,” and your body still isn't responding the way it used to. So what changed? In this episode, I sit down with Dr. Carla DiGirolamo, a double Board-Certified Obstetrician/Gynecologist and Reproductive Endocrinologist specializing in caring for active and high-performing women, to unpack what's really happening to active women's bodies in mid-life and beyond.  We get into why hypothyroidism can be misdiagnosed because of chronic underfueling, what LEA and RED-S are (and why most doctors have never heard of them), hot takes on microdosing GLP-1s and muscle/bone loss for midlife women, and how HRT, testosterone therapy, and IUDs actually fit together. This isn't a decline — it's a detour, and it comes with a new playbook.  Resources from this episode can be found at: https://www.fuelwitherin.com/podcast/v/episode-33-why-your-workouts-stopped-working-and-what-actually-fixes-it-with-dr-carla-digirolamo  CONNECT WITH Dr. CARLA DIGIROLAMO Instagram profile | @dr_carla_d  Website | https://www.drcarlad.com  Substack Athletic Aging | https://www.athleticaging.blog FUEL YOUR PERFORMANCE Momentous is my go-to for high-quality, science-backed supplements → Offer: Use code FuelWithErin for 14% off one-time purchase and 35% off first-time subscriptions Shop here: https://crrnt.app/MOME/1KeXpK4v  LETS CONNECT: Instagram | @fuel.with.erin Youtube | @Fuelwitherin Website | https://fuelwitherin.com ========== Disclaimer: The information provided in this podcast and its show notes is for informational and educational purposes only.

    What I Learned Going Down the Peptide Rabbit Hole (So You Don't Have To): Microdosing GLP-1s, BPC-157, Peptide Stacking and the Wild West of Sourcing

    Send us Fan Mail Peptides are everywhere right now — and the previous Peptides for Women episode with Jennifer Woodward just scratched the surface. In this episode I share the research I went down the rabbit hole to understand the full landscape for myself, and give you all the CliffsNotes.  In this follow-up solo episode, I break down the regulatory shifts and sourcing landscape, the repair peptide family flooding your feed (BPC-157, TB-500, GHK-Cu, KPV) and the marketed stacks built from them, the longevity peptides (MOTS-c, Epitalon, Pinealon, collagen), and a full deep dive on GLP-1s — semaglutide vs. tirzepatide, microdosing, the food-noise effect, and the ongoing muscle-loss debate.  No hype, no fear-mongering — just what the research does and doesn't say, so you can make an informed call for your own body.

    Peptides for Women: A Foundations-First Guide with Jennifer Woodward

    Send us Fan Mail Peptides are having a moment — GLP-1s, BPC-157, growth hormone secretagogues (GHSs) — but most of what you're hearing skips the part that actually matters: none of it works if your foundations aren't in place.  Jennifer Woodward, a Certified Functional Diagnostic Nutrition Practitioner and Board Certified Functional Wellness Coach, and host of Peptides for Women, joins Erin to break down what peptides actually are, which ones have helped her and the women she works with, and why she requires protein, minerals, strength training, and sleep basics before adding peptides. She also shares which ones are worth your money in midlife — from GLP-1s for metabolic reset to the KLOW Stack for joint and gut repair.  We also get into the research behind peptides, how to avoid sketchy sourcing, and client stories that show peptides can mean very different things depending on where you're starting from. This one is your foundations-first, no-hype guide to peptides.

    How Women Over 40 Can Lose Fat When Nothing You Used to Do Works Anymore

    Send us Fan Mail Do you feel busier than ever, yet suddenly unable to handle the stress, workouts, and endless to-do lists like you used to? Welcome to life and fitness after 40. In this episode, Erin sits down with Stephanie Crassweller, founder of Vitality OET and Hormone + Menopause Functional Health Coach, to unpack why the strategies that used to keep high-achieving women afloat—pushing harder, cutting more, sleeping less—stop working once hormones start to shift. Stephanie walks through your capacity bucket: why your stress tolerance quietly shrinks in perimenopause even when nothing else in your life has changed, why progesterone (not estrogen) is usually the first hormone to drop, and how years on birth control can leave your body without ever producing it naturally. They also cover why HRT won't fix weight gain on its own, how one bad night of sleep can spike insulin resistance by 25%, and the nervous system resets Stephanie actually uses to stay out of fight-or-flight.
