2026/10/08
Low vitamin D can leave you more prone to bone injuries and illness, and it's more common in athletes than you might think. Few foods are good sources, and making enough from sunlight isn't a given, especially as the days get shorter.

Meal Prep for Busy Athletes: Simple Strategies to Save Time and Money
2026/09/24
Meal prep is a great way to make busy weeks easier, but it doesn’t have to mean spending your entire Sunday cooking identical, boring meals or blowing through your entire budget in one grocery haul.
In episode 146 of The Eat for Endurance Podcast, sports dietitians Sandra Frail and Kiana Gibson of No Sweat Nutrition join me to talk about meal planning and meal prep for active people, and ways to save money on both everyday and performance nutrition.

Amanda Brooks on Ditching Diet Culture and Discovering What Her Body Can Do
2026/09/10
Nutrition can be complex and personal, especially for athletes. Many people absorb misguided messaging about "good" and "bad" foods and what your body should look like, and lose sight of what's actually important for performance and overall health.
In episode 145 of The Eat For Endurance Podcast, longtime runner and experienced run coach Amanda Brooks joins me to talk about shifting her focus from restricting food to fueling more freely, resulting in stronger runs and a better relationship with her body.
Amanda and I discuss:
Growing up in the fat-free era, with diet culture and negative body image messagingHow running went from a weight-loss tool to a reason to fuel properlyHow she now fuels long runs and races Fueling myths and misconceptions Amanda often sees among the runners she coachesHow nutrition and exercise needs shift for female runners as they ageHow both food and running can bring people together A big takeaway from this conversation is that nutrition doesn't have to be about weight loss, or taking things away. It can (and should) be about giving your body what it needs to run, recover, and feel its best.

Can You Trust AI for Nutrition Advice?
2026/08/27
AI is everywhere these days and more and more people are turning to ChatGPT and other AI tools for nutrition and fueling advice. While AI can be incredibly useful for things like brainstorming meal ideas or collecting general nutrition information, it's not a substitute for individualized nutrition or medical advice.
In episode 144 of The Eat for Endurance Podcast, Sports Dietitian Jessica Isaacs, MS, RDN, joins me to talk about AI and nutrition, including:
Why athletes are increasingly turning to AI for fueling guidanceWhat AI gets right (and wrong) when it comes to nutrition and healthUsing AI for general information versus individualized nutrition adviceHow to fact-check AI-generated informationPractical examples of when AI can be useful for active peopleWhy AI should be used alongside dietitians and other health professionals (not instead of)A big takeaway from this conversation is that AI can be helpful, but it shouldn't be your nutrition decision-maker.

7 Ways Sports Nutrition Has Changed Since I Started Podcasting
2026/08/12
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 benefitThe rise of individualized sweat sodium testing and all the hype surrounding electrolytesThe increase in REDS awareness and why that matters for athletesWhy creatine has become one of the most talked about supplements, and if you should take itThe protein boom and what you really need to know about this macroThe prevalence of GLP-1 meds and what this means for athletesHow athletes are talking about fueling more openly than ever beforeTo 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.
Thank you again for listening, sharing the podcast, and supporting Eat for Endurance over the past seven years. Here's to the next chapter!

Fiber for Athletes: Timing, Gut Health & How Much You Need
2026/07/30
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 importantDifferent fiber types and how much you should be eating each dayHow fiber supports gut health, blood sugar, heart health, and moreWhen to eat fiber and when to avoid it around training and racingWhat "fibermaxxing" is and if you should do itOur favorite high-fiber foods for athletesWhether fiber supplements and fortified foods have a place in your dietSpecial considerations for vegan and vegetarian athletesPractical ways to increase your fiber intake without upsetting your gutA 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?
2026/07/16
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
2026/07/02
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
2026/05/28
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 ([email protected])!

Why Endurance Athletes Struggle with GI Issues (And How to Actually Fix Them)
2026/05/14
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.

How Much Protein Should Athletes Actually Eat?
2026/04/30
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!).

GLP-1 Medications: What Active People Need to Know
2026/04/16
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.

2026/04/02
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.
Jennifer helped launch the global bar category back in 1985 with her husband, long before fueling strategies became a core part of endurance performance. But this conversation goes far beyond the history of energy bars.
Jennifer and I discuss:
How she ran her first marathon at the age of 13Her early interest in cooking and food scienceWhat it was like building PowerBar out of her apartment while still in collegeHow she balanced running a business, training, and raising 6 childrenHow her relationship with running changed after having kids, and especially after her husband's sudden death in 2004Why learning the drums later in life became such an important outletWhat inspired her return to the bar business decades later with JAMBARJennifer’s story is a powerful reminder that your identity is never fixed. How you move and fuel your body as well as how you spend your time is meant to evolve across different seasons of life.

Why Thyroid Health Matters for Athletes
2026/03/19
What if your low energy or stubborn performance plateau have little to do with your training, and everything to do with your thyroid?
In episode 133 of The Eat for Endurance Podcast, I’m joined by Katie Morra, MS, RD, LDN, IFMCP, to talk all about thyroid health for athletes.
Katie is a Registered Dietitian and former Division 1 athlete who specializes in complex chronic illness. Her practice, Gut Honest Truth, focuses on the identification and treatment of root causes behind chronic inflammatory conditions, autoimmune disease, gastrointestinal dysfunction, and thyroid dysfunction.
In this episode, Katie and I discuss:
What the thyroid actually does and how it impacts almost everything in the bodyCommon signs of thyroid dysfunction in active peopleThe connection between underfueling, stress, and thyroid functionWhy looking at TSH alone doesn’t tell the full story, and what you should get tested insteadKey nutrients for thyroid health How gut health impacts nutrient absorption and thyroid functionWhen someone may need thyroid medicationThe difference between Hashimoto’s and hypothyroidism caused by underfuelingPractical nutrition and lifestyle strategies to support the thyroidThis is a complex topic and we only scratch the surface, but it’s a really helpful starting point if you’ve ever wondered whether your thyroid could be playing a role in how you feel or perform.
