Macro Rationale

"A gram of protein and carbohydrates each contain 4 calories, while a gram of fat contains 9 calories. Balancing these is key to performance and body composition."

What are Macros?

Macronutrients, or "macros," are the three main types of nutrients your body needs in large amounts to function: Protein, Carbohydrates, and Fats. Unlike micronutrients (vitamins and minerals), macros provide the actual energy (calories) your body burns.

The Protein Priority

Protein is essential for muscle repair, immune function, and hormone production. For those looking to build muscle or lose fat without losing muscle mass, a higher protein intake (30-45%) is often recommended.

Fats and Carbs

Carbohydrates are your body's preferred source of energy for high-intensity activity. Fats are necessary for brain health, vitamin absorption, and sustained low-intensity energy. The ratio between these two can be adjusted based on your personal preference and activity type.

Flexible Dieting

The most successful diet is one you can stick to. Use these macro targets as a guide, but don't obsess over hitting them perfectly every day. Focus on hitting your calorie goal and protein target first, then let the carbs and fats fill in the rest.

Frequently Asked Questions

What are macronutrients?

Macronutrients (macros) are the primary building blocks of your diet: proteins, fats, and carbohydrates. They provide the energy your body needs to function.
