CrossFit Diet: A Day in the Life of 3 CrossFit Athletes Nutrition

Ever wonder what fuels a CrossFit athlete? What drives them to their success? We know a big portion of it comes from discipline and hard work. But we also know that a lot can come from their diet and training. So we decided to ask some of the top CrossFit athletes on how they manage their CrossFit diet and what CrossFit supplements they use to support their training.

This blog will go over the CrossFit diet plan of CrossFit Games athletes. The CrossFit diet plan to lose weight will not necessarily be exemplified in these CrossFit diet plans, as a majority of these athletes are looking to increase their performance in their CrossFit training, gain muscle, and improve their body size, not necessarily weight loss.


What is the CrossFit Diet?

In a typical CrossFit diet plan, you will most likely see macronutrients like lean proteins, carbohydrates that consist of starchy vegetables, and monosaturated fats. Crossfitters tend to stay away from foods that are on the high glycemic index, foods that are more processed and high in sugar that tend to cause more inflammation. A crossfitters goal is build up their glycogen stores so they have the energy needed for their next WOD. Very rarely will you see their CrossFit diet plan with a goal of weight loss, unless they are looking to cut a “gaining” season. Again, you’ll often see common macronutrients of lean proteins, carbohydrates that are starchy vegetables, and monosaturated fats (oil).

Before we dive into these athletes CrossFit nutrition, let’s do a quick run-down of what macronutrients are and some of the common CrossFit diets among crossfitters.


What are macronutrients?

Macronutrients are the primary building blocks of your diet - protein, carbohydrates, and fat - which provide your body with energy. Protein provides the building blocks of the body, and not just to gain muscle. Every cell, from bone to skin to hair, contains protein. Carbohydrates fuel your body, especially your central nervous system, and brain, and protect against disease, according to the Mayo Clinic. Keep in mind that the type of carb you eat matters. Go for whole-grain, low glycemic carbs, not carbs on the high glycemic index. Low glycemic cards include legumes, fiber-rich starchy vegetables, etc. And finally, healthy fats support many of your body’s functions such as vitamin and mineral absorption, blood clotting, building cells, and muscle movement. Go for monounsaturated fats, these fats tend to be more anti-inflammation.

Zone Diet

The zone diet is often considered to be the best CrossFit nutrition model for optimal CrossFit training performance. This diet uses blocks. A block meal is a simplified unit for measuring the 3 macronutrients in your food (protein, carbohydrates, and fats). With the right balance of proteins, carbohydrates, and fats, you can control three major hormones generated by the human diet – insulin, glycogen and eicosanoids. In the zone diet, one block meal equals 7 grams of protein, 9 grams of carbohydrates, and 1.5 grams of fats. Learn more about how the zone diet works and how what a block meal looks like here.

Paleo Diet

The paleo diet is simple, if the caveman didn’t eat it, neither should you. When you’re following the paleo diet, you basically can eat foods that we could hunt and gather back in the day – foods like meats, fish, nuts, leafy greens, regional veggies, and seeds. This means no high glycemic index carbs and high inflammation processed foods like, pasta, bread, cereal, candy, etc. Instead of counting calories, macronutrients, and partitioning out a block meal like the zone diet, you just focus on eating the right foods. For some crossfitters, this a simple way to stay on top of their CrossFit nutrition. Learn more about the paleo diet and what foods you can and can’t eat at here.
