The Fight Before the Fight: Charles Stull, Director of Performance Nutrition at the UFC PI | Ep.017

Vote for Charles for Trainer of the year at The World MMA Awards! https://www.worldmmaawards.com/votenow/   When people think about the UFC, they picture the walkouts, the knockouts, the highlight reels. But long before fighters step into the Octagon, there’s another fight happening, one with the scale, with food, with the limits of the human body.   I sat down with Charles Stull, Director of Performance Nutrition at the UFC Performance Institute, to talk about that hidden battle. Charles has shaped how some of the greatest fighters in the world approach weight cutting, recovery, and performance. He’s not just a dietitian — he’s someone who’s helped redefine what it means to fuel athletes in one of the most demanding sports on earth.   In this conversation, we break down the science, the strategy, and the reality of nutrition in combat sports. We talk about what’s working, what’s broken, and what it really takes to push the limits of human performance inside the UFC.   For me, this was more than just an interview. It was a chance to sit across from someone who has seen behind the curtain, and who is changing the way fighters prepare for the fight before the fight.   ✅ Fuel Your Performance – Protekt Products Electrolytes that actually work.
