There's a persistent myth in the fitness world that you can't build serious muscle or perform at an elite level on a gluten-free diet. It's simply not true.
What is true is that navigating a high-performance diet while gluten-free takes a little more planning. This guide breaks down exactly how much protein you need, how to protect your gut, and how to time your nutrition around training.
