Podcast 82 - What Jeff Browning Learned After 10 Years of OFM
After more than a decade of competing at the highest level of ultra-endurance racing, Jeff Browning continues to refine one of the most important aspects of performance—how he fuels.
In this episode of the OFM Podcast, Peter Defty sits down with Jeff to discuss how his nutrition strategy has evolved over 10 years of using the OFM (Optimized Fat Metabolism) approach. Fresh off the Cocodona 250 and preparing for the Western States Endurance Run, Jeff shares the lessons he's learned from years of racing, testing, and adapting his fueling strategy.
Together, they explore why endurance nutrition doesn't have to be a choice between high-carbohydrate fueling and strict ketogenic diets. Instead, they explain how strategic carbohydrate use, metabolic flexibility, and individualized nutrition can help athletes improve performance, reduce gastrointestinal distress, and support long-term metabolic health.
The conversation also dives into emerging topics such as protein intake during ultra-distance events, hydration and electrolyte strategies, gut health, and why supporting recovery may be just as important as fueling the race itself.
Whether you're training for your first marathon, preparing for a 100- or 200-mile ultramarathon, or simply looking to better understand endurance nutrition, this episode offers practical insights backed by more than a decade of real-world experience.
In this episode you'll learn:
Why OFM is not a ketogenic diet
How strategic carbohydrates can support endurance performance
What Jeff learned after racing the Cocodona 250
The role of protein during races lasting longer than 10 hours
How gut health influences performance and recovery
Practical hydration and electrolyte strategies
Why metabolic flexibility may outperform nutrition extremes
If you're looking for a smarter, more sustainable approach to endurance fueling, this conversation is packed with actionable insights you can apply to your own training and racing.

Podcast 81 - Dr Alicia Newsome on Women's Hormonal Health
Most women are told their hormones are the problem.
But what if that’s only part of the story?
In this conversation, we dive into how metabolism, stress, and lifestyle are actually driving hormonal imbalances—and why quick fixes often fall short.
If you’ve been dealing with fatigue, stubborn weight, or feeling “off,” this might change how you see your health.
Join host Peter Defty for an inspiring conversation with elite OFM athletes Bree Lambert-Sanders and Joe Sanders, two masters-level competitors proving that peak endurance performance doesn’t end at 40—or 50. Bree shares her breakthrough season, including top finishes at UTMB-CCC and Kodiak 100K, while Joe brings decades of competitive insight and the science-backed wisdom of fat-based fueling. This episode dives into metabolic efficiency, stress, recovery, longevity, and how Vespa + OFM help athletes perform at their best at any age. A must-listen for ultrarunners, triathletes, and anyone curious about optimizing human performance.
