In CrossFit founder Greg Glassman’s original synopsis of CrossFit as a lifestyle, paleo was the way to go. That is, minimal carbs, lots of veggies and fruit and meat, and no processed foods. However, CrossFitters (both the high-level athletes and the everyday box-goers) follow all sorts of diets. What’s important is that you follow an eating pattern that supports your level of exercise and helps you meet your various wellness goals.
