If you want more energy, faster recovery, and better performance in the gym and in daily life, the way you fuel your body deserves as much attention as the way you train it.

This conversation looks at nutrition through a performance lens, with insights that apply whether you are training for the gym, long workdays, or full days of skiing in the mountains. Dr. Andrew Fix is joined by Katie Hardie, a board-certified holistic nutritionist and functional diagnostic nutrition practitioner, to talk about how food choices shape energy, recovery, focus, and consistency, and why many people struggle to see results even when they believe they are eating well. The discussion moves beyond calorie counts and into how digestion, stress, and food quality quietly influence how your body shows up day after day.

Katie shares a grounded approach to performance nutrition that prioritizes meals you can repeat and enjoy. They explore why food has to taste good to be sustainable, how to learn what balance of protein, fats, and carbohydrates works best for your body, and why lingering soreness or low motivation can be signs of under-fueling rather than overtraining. What changes when you start listening to how your body responds instead of following rigid rules? How might your workouts improve if recovery and fueling finally support each other?

This episode reframes nutrition as a practical performance tool that supports strength, stamina, and clarity, with ideas you can apply immediately without turning food into another source of stress.
