  2. Why Zach Bitter Went High Carb After 14 Years of Low Carb Fueling

    Why Zach Bitter Went High Carb After 14 Years of Low Carb Fueling

    What if the fueling strategy you’ve followed for years is no longer the one that best supports your performance? In Episode 131 of The Eat for Endurance Podcast, I’m joined by elite ultrarunner and coach Zach Bitter for a thoughtful conversation about his experience with both low and high carb fueling. After following a low carb diet for 14 years, including when he broke the World and American Records in the 100-mile distance, he decided to change course and try high carb fueling. It's been 8 months now of experimenting with more carbs, and so far, he’s had a very positive experience. Zach and I discuss: Why he originally went low carb as a younger ultrarunnerWhat his particular flavor of low carb fueling looked like in practiceWhat motivated him to dramatically increase his carb intake last yearHow high carb fueling has influenced his recent training and racingWhy you shouldn't make one single diet your whole identityThe importance of curiosity and flexibility for long-term health and performanceThis episode is full of nuance, and underscores the fact that there is no one-size-fits-all diet. As Zach says in the episode, don't be afraid to try something new, because if it doesn't work out, you can always go back to what you were doing before! 🎧 Tune in to learn more!

    (Re-Release) “Skinny Doesn’t Win Races”: Jessie Diggins on Fueling for Joy, Resilience, and Olympic Gold

    “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. 🎧 Tune in now for this inspiring conversation!

    How to Stay Healthy as an Athlete This Season

    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 functionThe J-curve relationship between exercise and immune health Why eating enough is key to preventing illnessThe role of carbs, specific micronutrients, and other fueling patternsWhy sleep and rest from exercise make your immune system more resilientWhat to do if you’ve been exposed to illness but aren’t sick yetDietary and lifestyle tips for when symptoms start showing upWhich supplements may be helpful, and when to take themHow your approach should differ when dealing with respiratory vs GI illness Immune health considerations during travel, including foodborne illnessIf 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.  🎧 Tune in to learn more! Links & Resources Follow Laura Ligos on Instagram and visit Laura's WebsiteIn 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." Join my membership, Fuel for Life Crew, for just $39/month (cancel anytime)Check out my free nutrition downloadsBrowse my library of nutrition masterclasses (all are included inside the Fuel for Life Crew membership)Interested in comprehensive, in-depth 1:1 coaching?

    Joe Corcione on Addiction, Recovery, and Everyday Ultra Running

    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 comeWhy small, consistent changes matter more than extremesHow 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 bodyWhy endurance athletes cannot only rely on exercise as a coping toolWhat sustainable ultramarathon training really looks likeHow he fuels himself during training runs and races🎧 Tune in to learn more!

    Do You Have A Healthy Relationship With Exercise?

    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 riskHow to tell if exercise is healthy or potentially harmfulWhat Leslie's message, "If you fuel it, you can do it" means in practiceThe connection between underfueling and over exerciseSigns that you might be weight suppressedWhat compassionate change can look likeAlso, 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.  🎧 Tune in to learn more!
