    Are GLP-1s Safe for Athletes?

    Many athletes are not good candidates for GLP-1s. But for some, these medications can be a useful tool. In episode 141 of The Eat for Endurance Podcast, I'm joined by fellow Sports Dietitian and endurance athlete Jennifer O'Donnell-Giles, MS, RDN for the final installment of my GLP-1 mini-series. Jenn brings 27 years of clinical experience to this conversation, along with a perspective that's evolved a lot over the past few years. Jenn and I discuss: How natural GLP-1 production can decline with ageWhy under-fueling is still the primary issue for many athletesWho should (and shouldn't) consider these medicationsPotential risks of GLP-1 use, including lean body mass loss and GI distressPotential benefits to inflammation, autoimmune conditions, gut health, and moodNutrition and supplement strategies when appetite is lowerDosing and microdosing for therapeutic use, not just weight lossWhy athletes cycle on and off GLP-1s, including around race trainingJenn's own story: early menopause, a cardiovascular family history, and how a short course of GLP-1s changed her health and performanceJenn's biggest takeaway: in the athlete population, a GLP-1 is just one piece of the puzzle, and works best alongside solid nutrition and lifestyle habits. Weight loss can be part of why someone uses one, but there are other potential benefits as well. Whether a GLP-1 is right for an athlete depends on who they are, why they want it, and whether the foundation is already in place. It's not appropriate for everyone, especially anyone with a history of disordered eating or a complicated relationship with food.  Tune in for a nuanced, experience-based look at where these medications can genuinely help endurance athletes, and where they can do real harm.

    Your Iron Questions, Answered: Everything Athletes Need to Know

    Iron deficiency is one of the most misunderstood nutrition issues affecting active people, and it's a lot more complicated than a single lab value. In episode 140 of The Eat for Endurance Podcast, I'm joined by fellow Sports Dietitian Callie Roseland, MS, RDN, CSSD to break down everything you need to know about iron and ferritin as an active person. Callie and I discuss: The difference between iron deficiency and anemiaWho's most at riskCommon signs and symptoms of low iron and ferritinWhich blood tests to orderWhy "normal" lab values aren't always optimal What low ferritin but "normal" iron actually meansHow gut health as well as different foods influence iron absorptionHow much iron you need from food, plus meal/snack ideasWhen supplementation makes senseIron supplement timing and practical strategiesCallie's mantra throughout the episode is simple but powerful: "Test, don't guess." Understanding WHY your iron is low is what allows you to address the root cause, not just mask symptoms with a supplement.  Tune in for the full breakdown on testing, supplementation, and nutrition strategies to support healthy iron and ferritin levels.

    What Is Food Noise? A Dietitian's Personal Experience with GLP-1 Medications

    GLP-1 medications are taking the world by storm, but the conversations surrounding them can lack nuance. That’s why I’m doing a 3-part podcast series with three different dietitians all about these drugs. ICYMI, we kicked things off with GLP-1 Medications: What Active People Need to Know. The series continues in episode 138 with Summer Kessel, RD, CSOWM, a Certified Specialist in Obesity and Weight Management and GLP-1 nutrition expert. Summer also has personal experience taking GLP-1s herself, which brings a unique perspective to this conversation. Summer and I discuss: What food noise is, and how it differs from hunger or cravingsHer personal experience with obesity, weight loss, and taking GLP-1sOverlap between food noise, chronic dieting, and disordered eating patternsWho should (and shouldn't) be on these drugs Risks and benefits of GLP-1 use in different populationsWhy inappropriate GLP-1 use cases shouldn't overshadow people who genuinely need these drugsHow weight stigma and judgment can make GLP-1 conversations even more difficultWhy compassion, individualized care, and ongoing professional support matter I hope this episode helps you better understand GLP-1 medications and the experiences of those who use them. I know this is a controversial topic...questions and feedback are always welcome (claire@eatforendurance.com)!  🎧 Tune in for the full conversation!

    Why Endurance Athletes Struggle with GI Issues (And How to Actually Fix Them)

    In episode 137 of The Eat for Endurance Podcast, I’m joined by Sports Dietitian Kylee Van Horn, RDN for a deep dive into one of the most common (and frustrating) challenges endurance athletes face… GI issues. From nausea and vomiting to bloating, cramping, and diarrhea, GI symptoms can seriously impact training, racing, and confidence around fueling.  The tricky part? It’s usually not just one thing causing the problem. Kylee and I discuss: Why GI issues are so common during endurance exerciseThe difference between upper vs. lower GI symptomsWhy you may need to stop blaming the gelsCommon fueling and hydration mistakes that contribute to GI distressThe role of underfueling and low energy availabilityGut training and improving carb tolerance during exerciseFueling considerations for marathons, triathlons, and ultrasWhen GI symptoms may warrant further medical evaluationWhile GI challenges are common in endurance athletes, they are not something you just have to accept as “normal.” With the right strategy, support, and a bit of troubleshooting, most athletes can significantly improve their symptoms. 🎧 Tune in to hear the full conversation!

    How Much Protein Should Athletes Actually Eat?

    In episode 136 of The Eat for Endurance Podcast, I’m joined by Holley Samuel MEd, RD, CSSD, CPT to break down one of the most talked-about topics in the nutrition world right now… protein! From social media trends to grocery store shelves, protein is everywhere these days. And while it is essential for performance, recovery, and overall health, the messaging around it has left a lot of athletes confused about how much they actually need. In this episode, we cut through the noise and bring the conversation back to what  matters most... having a balanced approach to fueling that fits your unique needs and active lifestyle.   Holley and I discuss: Why protein is everyone's favorite macro right nowGeneral protein targets for athletes (and why more isn’t always better)How protein needs change across life stages and training demandsAnimal vs. plant protein and what athletes should know about bothCommon protein myths and where recommendations go wrongProtein timing considerationsWhen protein supplements can be helpful (and when they’re not)The bottom line is: protein matters, but so does everything else on your plate (especially my favorite… CARBS!). 🎧 Tune in to hear the full conversation!

    GLP-1 Medications: What Active People Need to Know

    GLP-1 medications are everywhere right now, but the conversation around them often lacks nuance and is rarely discussed through the lens of active people. That’s exactly why I’m doing a 3-part podcast series all about GLP-1 medications, with athletes in mind. In this series, you’ll hear from three dietitians who regularly work with GLP-1 agonists and each bring a unique clinical and personal perspective to the conversation. I'm kicking things off in episode 135 with Courtney Smith, MS, RD, CDCES, a sports dietitian, diabetes specialist, and longtime endurance athlete. Together, we break down the basics of GLP-1 medications and what active people need to know in the context of training and health. Courtney and I discuss: The history of GLP-1 medications, especially in diabetic populationsWhy they have exploded in popularity in recent yearsHow the various drugs on the market differ, plus dosing practicesThe benefits and side effects she's observed in practiceHow crucial it is to get ongoing professional support when on GLP-1's, and why you still need to work on diet & lifestyle changesWhy she generally does not recommend GLP-1 drugs for most athletesIf you’ve been hearing about GLP-1 medications and wondering how they may affect your training, fueling, recovery, blood sugar, or overall health as an active person, this episode will answer your questions while laying an important foundation for the rest of the series to come. 🎧 Tune in for the full conversation!

    What happens when your identity as an athlete evolves, but your passion for movement, innovation, and challenge stays the same? In episode 134 of The Eat for Endurance Podcast, I’m joined by Jennifer Maxwell, co-founder of PowerBar and creator of JAMBAR, to talk about running, entrepreneurship, fueling a large, active family, and finding new passions later in life.
