Example Calculation
Let’s understand how the calculator works with a real example:
- Total Calories: 2000
- Protein: 30%
- Carbs: 40%
- Fats: 30%
Step 1: Calculate Calories for Each Macro
- Protein: 2000 × 30% = 600 calories
- Carbs: 2000 × 40% = 800 calories
- Fats: 2000 × 30% = 600 calories
Step 2: Convert Calories to Grams
- Protein: 600 ÷ 4 = 150g
- Carbs: 800 ÷ 4 = 200g
- Fats: 600 ÷ 9 = 66.67g
Final Result:
- Protein: 150 grams
- Carbs: 200 grams
- Fats: 66.67 grams
This gives you a clear daily nutrition target.
