Example Calculation

Case Study:

A 30-year-old female, weighing 70 kg and measuring 165 cm tall, moderately active, aiming to lose weight.

Caloric Needs:

1,800 kcal (TDEE adjusted for weight loss).

Macro Split:

40% carbohydrates, 30% protein, 30% fat.

Results:

- Carbs: 180g (4 calories/gram).

- Protein: 135g (4 calories/gram).

- Fats: 60g (9 calories/gram).

How to Calculate Macro Percentages from Grams

To determine macro percentages:

  1. Multiply grams of carbohydrates and protein by 4 (calories/gram) and fats by 9.
  2. Sum the total calories.
  3. Divide each nutrient’s calorie value by the total and multiply by 100 for the percentage.

Example:

- Carbs: 180g x 4 = 720 kcal.

- Protein: 135g x 4 = 540 kcal.

- Fats: 60g x 9 = 540 kcal.

- Total: 1,800 kcal.

- Percentage: Carbs (40%), Protein (30%), Fats (30%).
