Fuelin Sessions

In this episode of Fuelin Sessions, Scott Tindal is joined by Dr. Alan McCubbin, accredited sports dietitian and Monash University researcher, to pressure-test carb loading against the new "Beyond Belief" review paper. They dig into why a 50-year-old practice rests on just two flawed double-blind trials; why old physiology studies were never designed to answer today's performance questions; and why blinding carbs is so hard. The takeaway isn't a debunk: lack of evidence isn't evidence of no effect. Carb loading stays. It's low-cost, low-risk, and worth it.

In this episode of Fuelin Sessions, Scott is joined by applied sport scientist Jonah Rosner (ex-NFL, Nike Running Performance Lab NYC). They discuss why mechanical tension — not heavy weight — drives muscle growth, how blood flow restriction builds similar muscle at 20–30% of your max, who benefits most from injured athletes to hospital patients, and the practical protocol: limb occlusion pressure, the 30-15-15-15 scheme, and BFR's role in recovery and pain relief.

In this episode of Fuelin Sessions, Scott is joined by professional runner and Puma athlete Lucy Reid. They discuss her recovery from a medial meniscus root repair and eight weeks non-weight-bearing, why the biggest nutrition mistake injured athletes make is easing off exactly when fueling matters most, why recovery often means eating more rather than less, a supplement protocol driven by blood testing and retesting instead of guesswork, the rehab tech behind her comeback (blood flow restriction, muscle stim, and the AlterG treadmill), the DEXA scan showing under 3% muscle asymmetry, and her return to racing at the British 10K Championships after 16 months out.

In this episode of Fuelin Sessions, Scott is joined by Fuelin dietitian and triathlete Megan Foley. They discuss a new study of female athletes at the 2024 Nice Ironman World Championships that found most fell short of their carb-loading targets, why the gap on race day is rarely about knowledge and almost always about execution, how "eating clean" and too much fiber can sabotage a race, the finding that athletes who fueled more finished faster, the mindset shift from training to eat to eating to train, and the lack of female representation in sports-nutrition research.

In this episode of Fuelin Sessions, Scott is joined by running coach and writer Mario Fraioli. They discuss his recovery from disordered eating and the "lighter is faster" myth that still lingers in endurance sport, the influence a coach's words can have on an athlete for decades, the super-shoe and fueling revolution behind today's tumbling marathon times, why no endurance champion trains low-carb, and a candid take on doping and the case for more transparent testing.

Content note: this episode discusses disordered eating. In the US, the National Alliance for Eating Disorders runs a free, clinician-staffed helpline (allianceforeatingdisorders.com).

In this episode of Fuelin Sessions, Scott is joined by Chief Fueling Officer Daniela Ryf. They discuss her transition from professional athlete to lifestyle, her hesitancy to jump on the latest supplement trends, the importance of consistency, and a newfound realization of how enjoyment and social connection can make a big difference in fitness.

Are shortcuts killing what makes sport worth doing? Scott Tindal and co-host Jan dig into the Enhanced Games and performance-enhancing drugs — and why taking the easy route strips away the consistency, the work, and the discomfort that give endurance sport its meaning.They also take on the optimization trap — why athletes become "prisoners to the numbers" with wearables like Whoop and Oura — before getting practical on real-food fueling, protein and meal timing, and the carb-loading science most athletes get wrong.

In this episode, Scott sits down with Megan Foley to talk about her 5th-place finish in the women’s pro field at Ironman 70.3 Chattanooga. They over what her training actually looked like, where her race-week fueling went sideways, the post-race cherry juice, and they unpack how stepping back from full-time racing produced her best long-course result.

In this episode of Fuelin Session, Scott sits down with Dr Alan McCubbin to work through the latest debate in endurance nutrition. Does REDS syndrome actually hold up? They cover Penny Slater's new paper on what athletes and coaches misunderstand about under-fueling, the Areta-led paper challenging the IOC's REDS model, and why the gap between energy availability and energy balance trips up so many athletes.
