  7 Ways Sports Nutrition Has Changed Since I Started Podcasting

  Aug 12, 202629 minS8

  Seven years ago, I hit publish on the very first episode of The Eat for Endurance Podcast. At the time, elite athletes weren't talking as openly about how they fueled for training and racing, and the sports nutrition product market was only a fraction of its current size. In episode 143 of The Eat for Endurance Podcast , I reflect on 7 ways the sports nutrition world has shifted since I started my show back in 2019. I share the big themes I've observed, what I think we've gotten right, and where I think athletes should use caution. Here are the 7 topics I cover: How high-carb fueling became popular, and who may or may not benefit The rise of individualized sweat sodium testing and all the hype surrounding electrolytes The increase in REDS awareness and why that matters for athletes Why creatine has become one of the most talked about supplements, and if you should take it The protein boom and what you really need to know about this macro The prevalence of GLP-1 meds and what this means for athletes How athletes are talking about fueling more openly than ever before To celebrate the podcast's 7-year anniversary, I'm offering something I've never offered before: one-off 1:1 Fueling Sessions (60 minutes each). If you've been looking for personalized nutrition guidance but aren't ready to commit to a full coaching program, this is a chance to get your questions answered and leave with practical, individualized recommendations. Only 7 sessions are available on a first-come, first-served basis. This is open to new or existing clients.

  Fiber for Athletes: Timing, Gut Health & How Much You Need

  Jul 30, 202655 minS8

  Fiber has been having a moment lately. With social media trends like “fibermaxxing" on the rise and countless fiber-rich products hitting the market, it’s easy to get the misguided message that more is always better. So...how much fiber do athletes actually need? In episode 142 of The Eat for Endurance Podcast , fellow Sports Dietitian Angie Dye, MS, RDN, CSSD , joins me to answer that question and explain how to include fiber to support health without sabotaging your training. Angie and I discuss: What fiber is and why it's so important Different fiber types and how much you should be eating each day How fiber supports gut health, blood sugar, heart health, and more When to eat fiber and when to avoid it around training and racing What "fibermaxxing" is and if you should do it Our favorite high-fiber foods for athletes Whether fiber supplements and fortified foods have a place in your diet Special considerations for vegan and vegetarian athletes Practical ways to increase your fiber intake without upsetting your gut A big takeaway from this conversation is that athletes shouldn't fear fiber. They just need to be strategic with it! Tune in to hear the whole conversation.

  Are GLP-1s Safe for Athletes?

  Jul 16, 20261h 26mS8

  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 age Why under-fueling is still the primary issue for many athletes Who should (and shouldn't) consider these medications Potential risks of GLP-1 use, including lean body mass loss and GI distress Potential benefits to inflammation, autoimmune conditions, gut health, and mood Nutrition and supplement strategies when appetite is lower Dosing and microdosing for therapeutic use, not just weight loss Why athletes cycle on and off GLP-1s, including around race training Jenn's own story: early menopause, a cardiovascular family history, and how a short course of GLP-1s changed her health and performance Jenn'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

  Jul 2, 20261h 32mS8

  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 anemia Who's most at risk Common signs and symptoms of low iron and ferritin Which blood tests to order Why "normal" lab values aren't always optimal What low ferritin but "normal" iron actually means How gut health as well as different foods influence iron absorption How much iron you need from food, plus meal/snack ideas When supplementation makes sense Iron supplement timing and practical strategies Callie'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.

  Jun 11, 20261h 14mS8

  First, a huge congratulations to Grayson and her husband on the recent birth of their daughter, Violet!

Grayson and I discuss: Her transition from soccer to collegiate and eventually professional running Years of unexplained GI symptoms, misdiagnoses, and the road to finally getting answers Training and race-day fueling strategies, including for athletes with Crohn's disease Tried and tested strategies to alleviate performance anxiety Therapy, medication, and other mental health tools that have helped her Her move from sub-ultra distances to the 50K Training and fueling through pregnancy as a professional athlete Whether you're navigating a chronic illness, have felt dismissed by a healthcare provider, or want to fuel smarter and show up to race day with less anxiety, this episode is for you. 🎧 Grab your headphones, because this is a good one!
