Leading the OFM Coaching Team is Peter Defty, the original developer of the OFM Program/Protocol. Peter pioneered the concept of fat adapted performance in 2000 first personally, then using running friends as guinea pigs then professionally when he joined Vespa.

From the onset athletes began to win, podium and set records using Vespa and the OFM protocol, however, these early successes were dismissed as anecdotal. Peter's athletes comprised the majority of the LCD cohort in the ground-breaking FASTER Study (Volek et.al.) A self-described empiricist (but one with a BS in Biology from UC Davis), Peter is constantly looking into and experimenting with how to further OFM to yield real world results.
