Mathematical Formulas & Calculation Methods

Macronutrient Calorie Conversions

Standard energy densities: Protein = 4 kcal/g, Carbohydrates = 4 kcal/g, Fats = 9 kcal/g.

Protein (g) = (Total Cal × Protein%) / 4 | Carbs (g) = (Total Cal × Carb%) / 4 | Fat (g) = (Total Cal × Fat%) / 9

Worked Step-by-Step Examples

Example 1: 2,200 Calorie Target on a 30% Protein / 40% Carb / 30% Fat Split

"Calculate daily grams and per-meal breakdown for 3 meals per day."

Steps:

Protein Calories = 2,200 × 0.30 = 660 kcal → 660 / 4 = 165g Protein.
Carbohydrate Calories = 2,200 × 0.40 = 880 kcal → 880 / 4 = 220g Carbs.
Fat Calories = 2,200 × 0.30 = 660 kcal → 660 / 9 = 73g Fat.
Per Meal (3 meals/day): 165/3 = 55g Protein, 220/3 = 73g Carbs, 73/3 = 24g Fat per meal.

Result: Daily: 165g Protein, 220g Carbs, 73g Fat (Per Meal: 55g P / 73g C / 24g F)
