What Are Macronutrients?
Macronutrients (macros) are the three main nutrients that provide energy: protein, carbohydrates, and fat. Each plays a vital role in your body:
- Protein (4 cal/g): Builds and repairs muscle, supports immune function
- Carbohydrates (4 cal/g): Primary energy source, fuels brain and muscles
- Fat (9 cal/g): Hormone production, vitamin absorption, cell structure
Macro Ratios by Goal
Weight Loss
Higher protein (35%) helps preserve muscle mass during a calorie deficit. Moderate carbs (35%) and fat (30%) provide balanced energy.
Maintenance
Balanced approach with 30% protein, 40% carbs, and 30% fat. Suitable for maintaining current body composition.
Muscle Gain
Higher carbs (45%) provide energy for intense workouts and muscle growth. Protein at 30% supports muscle synthesis, with 25% from fats.
