How It Works

How to Calculate Macros Per Recipe

Formulas

Total Calories = (Protein x 4) + (Carbs x 4) + (Fat x 9)

Per Serving = Total / Number of Servings

Calorie Values

  • 1 g protein = 4 kcal
  • 1 g carbohydrate = 4 kcal
  • 1 g fat = 9 kcal

    • Worked Example

    A recipe has 80 g protein, 120 g carbs, 60 g fat, and serves 4.

    total_protein_g = 80total_carbs_g = 120total_fat_g = 60servings = 4
    1. 01Total calories: (80 x 4) + (120 x 4) + (60 x 9) = 320 + 480 + 540 = 1340 kcal.
    2. 02Per serving: 1340 / 4 = 335 kcal.
    3. 03Protein: 80 / 4 = 20 g per serving.
    4. 04Carbs: 120 / 4 = 30 g per serving.
    5. 05Fat: 60 / 4 = 15 g per serving.

    Frequently Asked Questions

    What are macronutrients?

    Macronutrients (macros) are protein, carbohydrates, and fat. They are the three nutrients that provide calories and are needed in large amounts.

    How do I find the macros of each ingredient?

    Check nutrition labels or use the USDA FoodData Central database. Weigh ingredients for accuracy.

    What is a good macro ratio?

    It depends on your goals. Common ranges: 40/30/30 (carbs/protein/fat) for balanced diet, 40/40/20 for muscle building, 20/30/50 for low-carb diets.
