As nutrition goes, the simplest way in can put this is, EAT,


CrossFit aims to target nutrition to support physical activity but not body fat.  This nutrition plan is designed to control insulin spikes and promote fuel for optimal level of fitness.


The foundation of CrossFit’s hierarchy of development is Nutrition.  Proper nutrition builds a solid molecular foundation.  You cannot make up for poor nutrition with exercise.

CrossFit’s Nutrition Prescription

“Eat meat and vegetables, nuts and seeds, some fruits, little starch, and no sugar.  Keep intake to levels that will support exercise but not body fat.  Nutrition can be a touchy topic, like politics or religion, that people take very personally, but good nutrition is the foundation not only for general health but also for high-performance fitness.”

– Coach Greg Glassman
