I also give you a brief refresher on off-season nutrition, including how to avoid the biggest mistake I see athletes make after a goal race.

Can You Really Get All the Nutrients You Need on a Plant-Based Diet? Oct 22, 2026

Show notes

Can plant-based athletes get enough protein, iron, and other key nutrients to support their training and performance?

In Episode 148 of The Eat for Endurance Podcast, NYC-based sports dietitian Natalie Rizzo, MS, RD, joins me to talk about what athletes need to consider when following a plant-based diet. Natalie brings both personal and professional experience to this topic: she eats this way herself and specializes in plant-based eating for athletes through her practice, Greenletes.

Natalie and I discuss:

What plant-based actually means, and how you don't need to eliminate every single animal product to benefit
Common mistakes we see, like relying too heavily on processed meat alternatives and not eating enough nutrient-dense foods
How to balance a high-fiber diet with GI tolerance and increased energy needs
How to get enough protein by combining different plant sources
Iron considerations for vegan and vegetarian athletes, including ways to improve absorption
Other nutrients that require extra attention, such as vitamin B12, vitamin D, calcium, and omega-3s
How to know if plant-based eating is right for you, plus tips for getting started

Whether you’re vegan, vegetarian, or simply plant-curious, listen to the full episode to learn how to fuel effectively!

Is Your Vitamin D Holding You Back? Oct 08, 2026

Show notes

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.

In episode 147 of The Eat for Endurance Podcast, sports dietitian and researcher Kelly Pritchett, PhD, RD, CSSD, joins me to talk about:

Why vitamin D matters for bone health, muscle function, immunity, and athletic recovery
The best food sources of vitamin D, and why these foods alone won't cut it
How sun exposure, skin tone, sunscreen, clothing, season, and geography impact your ability to produce vitamin D
Common causes of low vitamin D and who's most at risk
What vitamin D blood test results mean and why recommendations for optimal levels differ
When to get your vitamin D tested and how time of year affects your results
When supplementation makes sense, and how dosage can vary
How vitamin D works with calcium, magnesium, and vitamin K, especially for bone stress injuries
What the research says about vitamin D, illness, and performance

Tune in for a practical, evidence-based look at vitamin D for athletes.

Meal Prep for Busy Athletes: Simple Strategies to Save Time and Money Sep 24, 2026

Show notes

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.

Sandra, Kiana, and I discuss:

The difference between meal planning and prepping
How to start meal prepping when you feel overwhelmed or short on time
Realistic meal prep strategies for busy athletes, families, and people with demanding jobs
How to use batch-cooked ingredients in different meals throughout the week
The role of convenience foods, leftovers, takeout, and “emergency meals”
How to reduce food waste and save money on everyday groceries
Budget-friendly protein, produce, and carbohydrate options
How to lower the cost of gels, sports drinks, bars, and other sports nutrition products

One of the biggest takeaways from this conversation is that the best meal prep strategy is the one that actually fits your life.

Tune in for lots of practical ideas you can put to use this week!

Amanda Brooks on Ditching Diet Culture and Discovering What Her Body Can Do Sep 10, 2026

Show notes

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.

Can You Trust AI for Nutrition Advice? Aug 27, 2026

Show notes

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.

7 Ways Sports Nutrition Has Changed Since I Started Podcasting Aug 12, 2026

Show notes

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 for Athletes: Timing, Gut Health & How Much You Need Jul 30, 2026

Show notes

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, 2026

Show notes

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.
