Example Calculation
Let’s understand with a real example:
- Total Calories: 2000
- Protein: 30%
- Carbs: 40%
- Fat: 30%
Step 1: Convert Percentages to Calories
- Protein Calories = 2000 × 30% = 600
- Carbs Calories = 2000 × 40% = 800
- Fat Calories = 2000 × 30% = 600
Step 2: Convert Calories to Grams
- Protein = 600 ÷ 4 = 150g
- Carbs = 800 ÷ 4 = 200g
- Fat = 600 ÷ 9 = 66.67g
Final Result:
- Protein: 150g
- Carbs: 200g
- Fat: 66.67g
This gives you a complete macro plan for your day.
