Macronutrient Quantities

🍗 Protein (4 kcal/g) 150g
🍚 Carbohydrates (4 kcal/g) 200g
🥑 Fats (9 kcal/g) 67g

Mathematical Formula

\text{Protein (g)} = \frac{\text{Cal} \times P\%}{4} \quad | \quad \text{Carbs (g)} = \frac{\text{Cal} \times C\%}{4} \quad | \quad \text{Fats (g)} = \frac{\text{Cal} \times F\%}{9}

Proteins and Carbs contain 4 calories/g. Fats contain 9 calories/g.

What are Macronutrients (Macros)?

Macronutrients are the nutritional compounds your body needs in large quantities to produce energy and maintain cellular structures. They consist of:

  • Protein: Essential for tissue growth and repair.
  • Carbohydrates: The body's primary and most efficient source of energy.
  • Fats: Vital for hormone synthesis, cell membrane integrity, and brain health.

Frequently Asked Questions (FAQ)

What is the best macro split for muscle gain?

A high-protein zone split (30-40% Carb, 30-40% Protein, 20-30% Fat) is highly effective for building muscle.

Do fiber grams count towards carbohydrates?

Fiber is a carb, but it is not digested. Many diet systems track "net carbs" (total carbs minus fiber).
