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.”
