303: Periodised Nutrition in Practice: Delivering the Plan Away From the Club

This week on the Science for Sport Podcast, Richard Graves is joined by Rachel Muse, one of the leading performance chefs working with elite athletes across professional sport.Rachel is the founder of Talk Eat Laugh, a specialist performance-chef service supporting athletes in their own homes. Her work bridges the gap between performance nutrition science and real-life eating habits, ensuring athletes follow precise nutritional plans without meals becoming clinical, restrictive, or culturally disconnected.In this episode, Rachel shares her unconventional journey from mathematics graduate to elite performance chef, and explains how chefs, nutritionists, and sports science teams work together to deliver periodised nutrition away from the training ground. The conversation explores how macronutrient targets are delivered in practice, how food preferences and cultural background shape compliance, and why fuelling the brain is just as important as fuelling the body.This is a rare insight into a part of the performance system that is often overlooked, but critical to recovery, consistency, and late-game performance.

In this episode, you will learn

• What periodised nutrition actually means in practice, beyond the theory
• How performance chefs work from nutritionist-led macro prescriptions
• Why chefs should not act as nutritionists, and where the professional boundaries sit
• How to deliver exact macronutrient targets without meals becoming boring or restrictive
• The role of carbohydrates in sustaining physical and cognitive performance late in matchesHow cultural background and food identity influence nutritional compliance
• Why elite performance nutrition is as much about psychology and trust as it is science
• What “success” really looks like when supporting elite athletes away from the club environment
