“Healthy, happy, and balanced athletes are the ones that make it across the finish line again and again throughout a long career and leave a legacy.”
— Jessie Diggins

Jessie Diggins is currently competing in her fourth and final Winter Olympics in Milan-Cortina. I interviewed her back in January 2021, just one week after her historic Tour de Ski win on some of the same Italian mountains she's skiing on now.

Since our recording, Jessie has become the most accomplished cross-country skier from the US, with 4 Olympic medals (she won her 4th one today!), 3 World Cup overall titles, 7 World Championship medals, and countless other accolades.

Even though it's no longer Covid times (thank goodness), this powerful conversation about fueling for joy, resilience, and longevity in sport remains just as relevant and important today.

In Episode 37, I’m honored to be joined by cross-country skier and Olympic gold medalist Jessie Diggins. She is not only dominating her sport, but also using her platform to promote healthy fueling, body positivity, and the importance of enjoying food without restriction.

Many fans first fell in love with Jessie during the 2018 Winter Olympics, where she and Kikkan Randall won the first-ever American gold medal in cross-country skiing. At the time of this interview, Jessie had also just won the Tour de Ski, becoming the first American to claim the title.

In this conversation, Jessie challenges the idea that leanness leads to success, reminding athletes that “Skinny doesn’t win races. Fast wins races.” She emphasizes that fueling well, prioritizing health, and embracing joy are essential to reaching the start line ready to race.

Wondering what you can realistically do to stay healthy during training, travel, and sick season? That's what Laura Ligos, RD (aka The Sassy Dietitian) and I chat about in Episode 130 of The Eat for Endurance Podcast.

This episode is not about immune “hacks” or doing more. Instead, we break down what actually supports immune health from a nutrition and lifestyle perspective, and explore where athletes often get tripped up when training, underfueling, poor sleep, and life stress stack up.

Laura and I discuss:

• How training, recovery, fueling, sleep, and life stress interact to influence immune function
• The J-curve relationship between exercise and immune health
• Why eating enough is key to preventing illness
• The role of carbs, specific micronutrients, and other fueling patterns
• Why sleep and rest from exercise make your immune system more resilient
• What to do if you’ve been exposed to illness but aren’t sick yet
• Dietary and lifestyle tips for when symptoms start showing up
• Which supplements may be helpful, and when to take them
• How your approach should differ when dealing with respiratory vs GI illness
• Immune health considerations during travel, including foodborne illness

If you’re dealing with stress, constant colds, lingering fatigue, or that frustrating feeling of being almost sick for days on end, this conversation is for you.

• In the J-Curve study we mentioned, it's worth noting: "The main limitation in the field is that most of the studies were conducted in military populations. Military intensive training introduces a wide range of bias because this intensive training usually is accompanied with dietary energy deficiency, sleep deprivation, and psychological stress."

In Episode 129 of The Eat for Endurance Podcast, I’m joined by ultrarunner, coach, and host of The Everyday Ultra Podcast, Joe Corcione.

Joe’s story is not the typical “natural-born athlete” narrative. He wasn't active growing up, and he struggled with drugs and alcohol as a teenager and young adult.

With a willingness to do the work (both physically and mentally) and make small changes, Joe gradually became sober and reshaped his identity. He went on to finish over 25 ultramarathons, coach runners around the world, and build the Everyday Ultra community.

Throughout our conversation, you’ll notice a powerful theme around the stories we tell ourselves and how these stories impact our behavior.

Joe and I explore:

• How his early beliefs that he was "unathletic" held him back for years to come
• Why small, consistent changes matter more than extremes
• How shifting from a fixed to a growth mindset helped him recover from addiction, start running longer distances, and determine what eating style worked best for his body
• Why endurance athletes cannot only rely on exercise as a coping tool
• What sustainable ultramarathon training really looks like
• How he fuels himself during training runs and races

Welcome to Season 8 of The Eat for Endurance Podcast! In this episode, I'm joined by Registered Dietitian Leslie Schilling, MA, RDN, CSCS, CEDS-C for an important conversation about exercise dependence, a pattern of compulsive movement that can threaten an athlete’s mental and physical health.

I heard Leslie speak on this topic at a conference and immediately knew I wanted to bring her on the show. This is partly because I struggled with exercise dependence in the past, and also because of how frequently I see people exercise beyond what is safe or recommended.

Leslie and I discuss:

• What exercise dependence is, and who is most at risk
• How to tell if exercise is healthy or potentially harmful
• What Leslie's message, "If you fuel it, you can do it" means in practice
• The connection between underfueling and over exercise
• Signs that you might be weight suppressed
• What compassionate change can look like

Also, toward the end of the episode, we walk you through a validated questionnaire to help you evaluate if you may be experiencing some level of exercise addiction.

Happy New Year, everyone! I'm back with one last bonus episode of The Eat for Endurance Podcast, this time with a behind-the-scenes look at what it’s actually like to work with a sports dietitian.

I walk through how I work with athletes inside my private practice, from start to finish. I discuss who 1:1 nutrition coaching is best for, how long athletes typically work with me, what my approach looks like, the kinds of changes I often see when athletes get the right support in place, and so much more.

I also share an overview of my monthly membership, Fuel for Life Crew, which is designed for athletes who want nutrition guidance, education, and community without full 1:1 coaching.

This episode is meant to be informative, not a sales pitch. It answers the most common questions I get about my services so you can decide if working with a sports dietitian makes sense for you!

I'm back with another short bonus episode, this time, all about how to fuel confidently during the holidays. I build on what I talked about in the last episode, so if you missed it, go back and give it a listen!

Between disrupted routines, travel, stress, social events, and allll the festive foods, it’s easy to slip into patterns like skipping meals or trying to “earn” or “burn off” what you eat. But the truth is: your nutrition needs don’t suddenly change just because it’s December.

In this episode, I share simple, compassionate strategies that help you stay fueled, enjoy the foods you love, and keep your energy steady during this busy season.

I cover:

• Why the holidays don’t require a new nutrition approach, just more flexibility
• The most common pitfalls people face
• Why skipping meals (especially breakfast) and "saving" calories backfire
• How to build a flexible holiday fueling framework
• Practical strategies for how to eat when you have a big meal or event planned
• What “checking in with your body” actually looks like
• Travel-friendly fueling strategies that keep you energized on the go
• How to move your body during the holidays without slipping into the earn/burn mindset

This is a must-listen if you tend to get thrown off your routine this time of year or find yourself feeling stressed about food, travel, or holiday meals. These tools will help you stay grounded without rigid rules, and enjoy the season more fully.

Happy December! I'm hopping back on the mic to bring you a bonus episode all about a topic that comes up every single year with my clients: off-season fueling.

When training volume drops and structure loosens, it’s easy to shift your focus away from your nutrition. And let's face it - it's also a crazy time of year. But what you eat in the off-season has a huge impact on your energy, recovery, general health, and how you feel heading into your next training cycle.

Whether you're taking real time off, switching activities or sports, or simply doing less of the same, this episode will help you stay fueled without micromanaging every bite.

In this episode, I cover:

• What the “off-season” actually is (and why it matters)
• Core fueling principles that don’t change, no matter the season
• How to adjust your nutrition when volume and intensity drop
• A practical look at carb needs during lower-volume training
• How to build balanced meals and snacks without tracking everything
• When (and when not) to consider body recomposition goals
• Why fueling your workouts still matters in the off-season
• How to use this time to build resilience for your next training cycle

This is a must-listen for anyone feeling a little lost with their nutrition after a big training cycle or who needs a refresher on foundational fueling strategies that are relevant year-round.
