Boost Your CrossFit Gains: Dietitian Reveals the Power of Carbs

Sam, a 34-year-old fitness enthusiast, is dedicated to transforming his physique through consistent exercise. With a commitment to weightlifting and CrossFit five times a week, Sam's primary goal is body recomposition. Weighing 208 pounds with approximately 20% body fat, he is focused on gaining muscle while reducing fat. Achieving such goals requires not only rigorous training but also a well-planned nutrition strategy. Sam recently shared his daily eating habits with Insider's Nutrition Clinic for expert feedback.

Sam follows a structured eating routine that begins with a 16-hour fasting period each day. During his eating window, he consumes between 2,600 to 3,000 calories. His first meal includes four eggs cooked in butter, a high-fiber tortilla, and a coffee blended with butter, heavy cream, Stevia, and MCT oil. This high-fat breakfast is designed to provide sustained energy. For his second meal, Sam opts for a protein-rich dinner featuring sources like steak, chicken, pork, or fish, accompanied by high-fiber vegetables and unsweetened almond milk.

Intermittent fasting, such as Sam's 16-hour fast, has become a popular approach for weight management. By limiting the eating window, fasting helps many individuals maintain a calorie deficit, which is essential for weight loss. However, experts point out that achieving a calorie deficit doesn't necessarily require fasting; it can be attained through other dietary strategies as well. While fasting can aid in controlling calorie intake, it's important to ensure that nutrient needs are met during eating periods to support overall health and fitness goals.

Dr. Mike Molloy, a sports dietitian and nutrition coach for professional CrossFit athletes, reviewed Sam's diet and provided valuable insights. He noted that while Sam's diet isn't bad, it is heavily focused on fats with very few carbohydrates. Given Sam's high-intensity CrossFit workouts, Dr. Molloy recommends increasing carbohydrate intake to better fuel his training. Carbohydrates are crucial for providing the glucose needed by the anaerobic energy system during intense exercises, enhancing both endurance and energy levels.

To better support his fitness objectives, Dr. Molloy suggests that Sam adjust his macronutrient distribution. Keeping within his daily calorie range of 2,600 to 3,000, Sam could benefit from a macronutrient ratio of 30% protein, 30% fat, and 40% carbohydrates. This adjustment would ensure he has enough carbohydrates around his workouts to maximize performance and recovery. Additionally, maintaining a protein intake of 0.75 to 1 gram per pound of body weight helps in muscle maintenance and growth, aligning perfectly with Sam's body recomposition goals.

Sam's dedication to his fitness routine is commendable, and with a few dietary tweaks, he can further enhance his results. Incorporating more carbohydrates into his meals will provide the necessary energy for his high-intensity workouts, aiding in better performance and faster recovery. By balancing his macronutrients effectively, Sam can continue to achieve his body recomposition goals while maintaining overall health and endurance.
