I think we’ve all heard the term, “you are what you eat.”? This might be the most common advice that you get from nutrition experts, regardless of your fitness journey.

(don’t shoot the messenger!)

This term simply means that you are the sole contributor of what you allow your body to take in…meaning you largely control the factors that ultimately affect your health, your nutrition, and your overall well-being.

Now, how does this relate to CrossFit? Understanding how much to eat and what to eat is very important to get the best results for your CrossFit training.

Today, we’ll delve into the basics of CrossFit macros. This will include the process of tracking macros, how to count them, the recommended foods you need to eat to “hit” your macros, and everything else you need to customize your meals!

What Are Macros and Why is Counting Macros Important for CrossFit Athletes?

Macronutrients or “macros” are the building blocks of our diet and provide us with the energy necessary to survive CrossFit WODs and metcons. Each macronutrient has a specific role and importance in supporting our overall performance.

Carbohydrates (“carb”) serve as the primary source of fuel for high-intensity exercise. Carbs provide the energy needed to power through intense CrossFit training sessions and support optimal performance (Spriet, 2014).

Proteins are essential for muscle growth and repair. They help in building and maintaining lean muscle mass (and making muscle gains), which is crucial for actually building strength and endurance from your CrossFit training (Phillips & Van Loon, 2011).

Lastly, we have fats. Fats play a vital role in providing sustained energy during workouts. This macronutrient also supports hormone function, which is essential for overall health and performance.

The Ultimate “Macros for CrossFit” Guidelines

As I’m sure you’re well aware, CrossFit workouts are a combination of high intensity, fast-paced, strenuous exercises  which and heavy lifting sessions. The grueling nature of these sessions is why you need to properly fuel and prepare your body through food! 

As a general rule, the CrossFit dietary needs focus on lean protein, healthy fats, and moderately low carbohydrate consumption. A good macronutrient ratio starting point is: 40% carbohydrates, 30% protein, 30% fat. However, you will likely find that you’ll need to make tweaks and adjustments over time.

Calculating Your Custom CrossFit Macros

Calculating your custom CrossFit macros is an essential step in optimizing your diet to meet your specific needs and goals. By determining your ideal macro breakdown of proteins, carbs, and fats, you can fuel your performance and support your CrossFit journey.

To calculate your custom CrossFit macros, several factors should be taken into consideration like your body composition, activity level, and performance goals. By understanding your unique requirements, you can develop a personalized macro ratio that aligns with your needs.

But how would you get the recommended numbers of macros for your body? The easiest way is to check for free online macronutrient calculators like calculator.net where you can easily fill out all necessary information about your body, and get the results in just a few clicks.

Once you have filled out the information about yourself, you have the option to choose what your goals would be. After that, you will be provided with results specific to your age, body weight and height like this:

It’s important to remember that your nutritional needs are different from everyone else. The best tip is consulting with a nutritionist or dietitian who specializes in sports performance and CrossFit can provide further guidance, ensure accurate calculations, and even give you a detailed plan for your meals. Precision Nutrition coaches are oftentimes not nutritionists or registered dieticians, but have received training specifically in calculating macronutrients for sports performance. 

I Got My Macros! What’s Next?

Now that you have the recommended amounts of macronutrients for your body, the next step is to prepare your meals and track how many of each macronutrient are consumed each day. The easiest way to do this is via food tracking applications like  myfitnesspal or Macrostax.

It would take you less than 5 minutes to record and input the meals you have consumed, and through these innovative applications, you can directly see if you’re hitting your daily goals!

Effective Ways To Adjust Your CrossFit Macros 

You might be doing CrossFit to build muscle, lose weight, or to simply tone your body. You have to remember that your macronutrient intake should be adjusted depending on the type of goal you want to achieve.

Here are ways that you can optimize your diet:

Losing Fat While Maintaining Energy

If your goal is to trim fat while maintaining energy levels for your CrossFit metcons, it’s important to create a moderate caloric intake deficit while still providing your body with the necessary nutrients to sustain performance.

The key to achieving this balance is by adopting a balanced macro ratio that enables sustainable fat loss without compromising energy and muscle mass. This approach typically involves:

• Reducing overall calorie intake by approximately 10-20% to create a modest caloric deficit
• Keeping protein intake at an adequate level to support muscle maintenance and recovery
• Adjusting carbohydrate and fat intake to maintain energy levels and optimize nutrient partitioning

Bulking Up: When to Increase Your Intake

If you’re aiming to bulk up and increase muscle mass, adjusting CrossFit macros involves increasing overall calorie intake to support muscle growth and performance. This can be achieved by:

• Increasing calorie intake by approximately 5-10% to meet the heightened calorie needs
• Boosting protein consumption to support muscle protein synthesis and recovery
• Incorporating additional carbs to provide energy for intense workouts and promote muscle glycogen replenishment

Maintaining Muscle Mass with Strategic Macro Balancing

When it comes to maintaining muscle mass during weight loss or any other phase, strategic macro balancing is crucial. This approach focuses on optimizing your macronutrient ratios to prioritize muscle preservation while still achieving (possible) body composition goals.

Key strategies for maintaining muscle mass include:

• Keeping protein intake high to prevent muscle breakdown and support muscle repair
• Incorporating strength training exercises to stimulate muscle growth and maintenance
• Adjusting carbohydrate and fat intake to support energy levels and overall nutrient balance
