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.

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 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.

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.

If you’ve tried to lose weight after kids and found that the old playbook from your 20s and 30s isn’t working, this episode is for you. In this solo episode, I share my personal journey inside a dedicated body recomposition program, which helped me lose fat and build muscle in just 6 months. After years of overtraining and under-fueling—which eventually led to a wrecked metabolism, hormones and energy crashes—I realized the playbook of ‘move more eat less’ was not going to work in midlife.

In this episode, I break down the exact methods I used to lose 10 pounds, heal my metabolism, balance my hormones, and build real muscle. I break down this episode into three main sections—nutrition, fitness and lifestyle. I talk about reverse dieting—the strategy where you incrementally increase your daily caloric intake by 50 to 100 calories each week to heal your metabolism, restore hormonal balance, and prepare your body to be in a state where it can lose weight. Whether you want to lose fat, build muscle, or heal your metabolism, this episode is a full playbook on what body recomp entails!

If you are a woman who runs, lifts weights, or loves staying active, ignoring your lower core might actually be holding your performance back. Studies show that athletes are far more likely to experience pelvic health conditions than non-athletes, yet the traditional fitness world completely ignores how childbirth and anatomy impact daily activity, lifting and running.

In this episode we sit down with Dr. Rachel Selman—a performance sport scientist, orthopedic and pelvic physical therapist, and author of the upcoming book Floor It. Rachel shares how the pelvic floor is a critical force absorber for your body, how to move beyond basic Kegels into contraction and lengthening, and how to integrate pelvic floor training into your everyday routine.

Tune in for actionable self-assessments, tips for runners and lifters, and advice on how to stop settling for leaks, injuries and pain from a dysfunctional pelvic floor. Your pelvic floor is your ultimate foundation—let's learn how to make it functional for performance and life.

Have you felt like everyone else received a manual to life that you somehow missed? In today's episode, we sit down with Katy Weber who is an ADHD advocate and coach, and host of the Women & ADHD podcast. Katy shares her personal story of being diagnosed during the pandemic at age of 45. Despite appearing as high-achieving, she was white-knuckling her way through daily life, battling internal hyperactivity, and mistaking her struggles for personal failure.

We dive deep into why so many women are overlooked by standard diagnostic tools, which were originally built around the behavior of young boys. Katy opens up about the eye-opening moments that changed everything—including how overcompensating to hide executive dysfunction leaves women completely exhausted.

Katy also shares why the real key to thriving with ADHD isn't a magical planner or app, but a radical shift in mindset toward self-acceptance, how she navigated her kids' ADHD diagnosis, the biggest misconceptions about adult ADHD, and what friends can do to better understand and support their friends with ADHD.

Have you tried elimination diets, cut out countless foods, and done random internet cleanses, only to find yourself still dealing with uncomfortable bloating, irregular periods and gut issues? In this episode, we sit down with licensed naturopathic doctor, yoga instructor, and women's health expert, Dr. Ashley de Luna. Dr. de Luna shares her personal journey navigating severe gut issues from her earlier days as a vegetarian to medical school, and reveals why the secret to her healing wasn't a restrictive vegan diet—it was regulating her nervous system.

We pull back the curtain on how the gut acts as our "second brain" and why true digestive wellness must start with a safe, grounded nervous system. Dr. de Luna breaks down the physiology of the vagus nerve and explains why eating while stressed prevents your body from properly releasing digestive enzymes. You will learn direct, actionable strategies to shift your body out of "fight or flight" and into a "rest and digest" state. We also touch on parasites, mold, leaky gut, and hormones, for a holistic conversation on gut health for women.
