❓ Frequently Asked Questions
How much protein do I need?
For muscle building, aim for 1.6–2.2g per kg of body weight. During weight loss, consume 1.2–1.6g/kg to maintain muscle mass. For general health, 0.8–1.2g/kg is recommended.
What is the best macro split?
This depends on your specific goals. A common starting point is 30% protein, 40% carbs, and 30% fat. You can adjust these based on your progress and preferences. For Keto, aim for ~5% carbs, 25% protein, and 70% fat.
Do I need to hit my macros exactly every day?
Prioritize your calorie and protein targets. Carbs and fats can be adjusted more flexibly. Consistency over the week is more important than achieving perfection every single day.
What should I eat first - protein, carbs, or fat?
Total daily intake matters more for body composition than meal timing. However, including protein in every meal (every 3–5 hours) helps optimize muscle protein synthesis.

Understanding Macronutrients for Body Composition
Macronutrients—protein, carbohydrates, and fat—are the primary sources of energy in your diet. Balancing these effectively is the cornerstone of evidence-based nutrition.
The Role of Each Macronutrient
- Protein (4 kcal/g): Essential for muscle repair, hormone production, and enzyme function. It is highly satiating and vital for muscle retention during fat loss.
- Carbohydrates (4 kcal/g): The preferred fuel for your brain and high-intensity activities. Fiber-rich sources are vital for digestive health.
- Fat (9 kcal/g): Crucial for hormone balance, nutrient absorption (vitamins A, D, E, K), and long-term health.
Suggested Macro Splits
- Weight Loss: ~30% protein, ~35% carbs, ~35% fat.
- Muscle Gain: ~30% protein, ~45% carbs, ~25% fat.
- Maintenance: ~25% protein, ~45% carbs, ~30% fat.
- Ketogenic: ~25% protein, ~5% carbs, ~70% fat.

Understanding Macronutrients for Body Composition
Macronutrients—specifically protein, carbohydrates, and fat—are the three essential nutrients that provide your body with energy (calories). Mastering the balance of these nutrients is the foundation of evidence-based nutrition, helping you reach your specific health goals effectively.
The Role of Each Macronutrient
- Protein (4 kcal/g): Essential for building and repairing muscle tissue, enzymes, and hormones. It is the most satiating macronutrient and is critical for protecting your muscle mass when you are losing weight.
- Carbohydrates (4 kcal/g): Your body’s primary fuel source, especially for brain function and high-intensity exercise. Focus on fiber-rich options to support gut health and keep you feeling full longer.
- Fat (9 kcal/g): Vital for hormone production (including testosterone and estrogen), absorbing essential vitamins (A, D, E, and K), and maintaining overall cellular health. It is the most calorie-dense macronutrient.
Macro Splits Based on Your Goals
- Weight Loss: ~30% protein, ~35% carbohydrates, ~35% fat (increased protein helps preserve muscle mass).
- Muscle Gain: ~30% protein, ~45% carbohydrates, ~25% fat (carbohydrates provide the energy needed for intense workouts and recovery).
- Maintenance: ~25% protein, ~45% carbohydrates, ~30% fat.
- Ketogenic: ~25% protein, ~5% carbohydrates, ~70% fat.
