How did Zach's diet change?

Zach Bitter made significant changes to his diet by adopting a low-carbohydrate approach over the past decade. He periodically adjusts his carbohydrate intake based on his training cycles. For instance, during the off-season, his diet is very low-carb, almost ketogenic, but he reintroduces more carbohydrates during intense training periods to support his performance 1 .
