In this episode of Progress in Practice, Charlie Reading is joined by Claire Fudge, founder of Fourth Discipline, clinical dietitian, performance nutritionist, and elite athlete.

Claire shares how she helps business professionals, founders, and executives who are also athletes optimise their health, nutrition, and performance - not just to feel better, but to compete and thrive for decades to come.

This is a conversation about far more than food. Claire opens up about growing up in a family bakery, the work ethic that shaped her, the life-changing accident that forced her to rethink her direction, and how that ultimately led her to build a business helping high performers accelerate both health and results.

It is a powerful episode on resilience, asking for help, building a fulfilling life, and staying deeply human in an AI-driven world.
