Are you eating the right way for your goals? Performance nutritionist Dr. Marc Bubbs has spent 20 years working with Olympic athletes, elite sports teams, and executives to optimize their health through diet and lifestyle. In this episode, he explains how nutrition isn’t one-size-fits-all, why carbs aren’t the enemy, and how small changes in your daily habits can have massive long-term impacts. Whether you’re a competitive athlete or just want to feel better, Dr. Marc breaks down the science behind what actually works—without the fads and misinformation that flood social media.

Key Moments
“We want you to enjoy life and food—if we do well Monday to Friday, you can live a little on the weekends.”

“If you wake up exhausted, lean on caffeine, and make bad food choices all day, the problem isn’t willpower—it’s how you set up your mornings and nights.”

“Most people think performance nutrition is just for Olympians, but the same principles apply whether you're training for gold or just trying to keep up with your kids.”
