How to Optimize Your Macros

Your macronutrient split dictates how your body uses the calories you consume. Here's a breakdown of how to structure your diet based on your fitness goals.

Protein

The building block of muscle. Essential for recovery, muscle growth, and preserving lean mass during a diet. Protein is also highly satiating, keeping you full longer.

Carbohydrates

Your body's preferred energy source. Carbs fuel high-intensity workouts, replenish muscle glycogen, and spike insulin (which is highly anabolic for muscle growth).

Fats

Crucial for hormonal health, particularly testosterone production. Fats also aid in the absorption of essential vitamins and provide a slow-burning energy source.

Macros for Maintaining

Maintaining your weight while improving body composition (body recomposition) requires a balanced approach. Focus on performance and recovery.
