At its core, CrossFit is about health and happiness. It’s not just about working out, it’s about transforming your lifestyle. However, the folks at CrossFit understand that it’s about finding the right program and diet for you.

As such, the CrossFit nutritional guidelines are more of a system – basic rules on how to eat for an improved lifestyle – that are adjustable to your own goals. However, understanding the basics of these rules is imperative to creating the balanced, healthy lifestyle that CrossFit can afford you.

The basic underlying concepts are based in the Paleo and Zone diets:


Paleo was the first “diet” of CrossFit. Inspired by the way our caveman and cavewoman ancestors would eat, it’s a simple system focused on consuming unprocessed and whole foods.

Paleo specifically has more rules on what you can and cannot eat, but within the CrossFit Nutritional Guidelines these are adjusted somewhat. They are broader, with the focus more on eating unprocessed, whole foods, than on telling you what to eat.

The Zone Diet

CrossFit also borrows the 40/30/30 macronutrient split from the Zone Diet. For people who are working out regularly, this provides enough carbs and fats required to power you through high-intensity workouts and keep the body’s natural processes running effectively. It also provides enough protein to help you build muscle and get stronger.

CrossFit also recognizes how high-glycemic, or high-sugar, carbs are worse for you than other types of carbs. Sugars should be limited as much as possible.

The CrossFit nutritional system uses these principles as a baseline for a performance and health-based diet. However, these are loose regulations that most gyms understand won’t fit everybody who comes through their doors.

the benefit of focusing on systems instead of a strict diet plan means that, by a skilled nutritionist, they can be adjusted to fit different goals.

Weight loss, muscle building, and high-performance goals can all be met within the boundaries of the above guidelines, by adjusting macronutrient and micronutrient intake as well as nutrient timing specific to your lifestyle.

Good coaches, like the ones at CrossFit Surrey, can teach you how to eat better for a healthier, more active lifestyle. They won’t only teach you what to eat and how much, but also the habits and tactics you’ll need to implement a new diet into your life, and destroy the old habits holding you back.
