The Eat for Endurance Podcast

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 messaging
How running went from a weight-loss tool to a reason to fuel properly
How she now fuels long runs and races 
Fueling myths and misconceptions Amanda often sees among the runners she coaches
How nutrition and exercise needs shift for female runners as they age
How 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.

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 guidance
What AI gets right (and wrong) when it comes to nutrition and health
Using AI for general information versus individualized nutrition advice
How to fact-check AI-generated information
Practical examples of when AI can be useful for active people
Why 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.

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. 
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 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.

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.
