How do you use continuous glucose monitoring as a non-diabetic athlete to optimize pre-workout fueling without chasing noisy data, and which metrics matter most to you? Can you share one moment when CGM feedback led you to change meal timing with a clear performance benefit?

I use CGM as a gentle guide, not a scoreboard. I look mostly at how stable my glucose stays in the two hours before training--no big dips or surges--since that affects how steady my energy feels. A memorable shift came when I saw that my morning workouts tanked if I ate overnight oats too close to training; pushing that meal 90 minutes earlier leveled my glucose curve and completely changed how sharp and strong I felt through the session.
