Colitis, Coaching, and Comebacks – Jimmy Baydoun’s Journey with Jason Theobald

In this episode of The Excellence Cartel, we sit down with competitor and coach Jimmy Baydoun to unpack a raw, eye-opening journey through colitis.

This condition nearly sidelined his physique goals and quality of life. From debilitating symptoms to endless frustration with conventional medical approaches, Jimmy shares how navigating a high-level prep with a chronic illness forced him to think differently about health, performance, and longevity.

But what changed everything was his partnership with coach Jason Theobald. Together, they began peeling back the layers, restoring gut health, reducing inflammation, and structuring training, nutrition, and supplementation to support healing and progress.

We get into the science, yes—but more importantly, the lived experience. Jimmy walks us through what it’s like to coach and compete while battling a condition that flares unpredictably and can drain every ounce of energy.

We cover the key protocols that worked, how mindset plays a critical role in chronic illness, and what he’d tell any athlete who feels like their body is working against them.

If you or your clients are battling gut dysfunction, autoimmune issues, or feel like they’re doing everything right but still spinning their wheels, this one is packed with information from Jason's 20+ years of knowledge.
