This week we’re joined by Sam Shepherd, Head of Sports Science at Precision Fuel & Hydration. Sam came to Precision after twelve years as a Lecturer and Reader at Liverpool John Moores University, where he specialised in exercise metabolism — particularly how the body uses carbohydrates and fats, and how training and nutrition can be shaped to improve both health and performance.
He’s not just a scientist, either. Sam is a practising sports nutritionist and a keen triathlete, with eight IRONMAN® finishes since 2018, including the World Championships in Kona in 2022.
