Macros Calculation Formula Explained
The calculator uses scientifically accepted nutritional formulas to convert calories into grams.
Protein Formula
Protein(g)=100×4Calories×Protein%
Protein contains 4 calories per gram, which is why we divide by 4.
Carbohydrates Formula
Carbohydrates(g)=100×4Calories×Carbs%
Carbs also provide 4 calories per gram.
Fat Formula
Fat(g)=100×9Calories×Fat%
Fats contain 9 calories per gram, making them more calorie-dense.
Understanding Macro Ratios
Different goals require different macro distributions.
1. Weight Loss Ratio
- Protein: 40%
- Carbs: 30%
- Fat: 30%
2. Muscle Gain Ratio
- Protein: 30%
- Carbs: 50%
- Fat: 20%
3. Balanced Diet
- Protein: 33%
- Carbs: 33%
- Fat: 34%
These ratios can be adjusted based on your personal fitness goals.
Example Calculation
Let’s understand the tool with a real example.
Given:
- Calories = 2000 kcal
- Protein = 30%
- Carbs = 50%
- Fat = 20%
Step 1: Protein Calculation
Protein calories = 2000 × 30% = 600 kcal
Protein grams = 600 ÷ 4 = 150g
Step 2: Carbohydrates Calculation
Carb calories = 2000 × 50% = 1000 kcal
Carbs grams = 1000 ÷ 4 = 250g
Step 3: Fat Calculation
Fat calories = 2000 × 20% = 400 kcal
Fat grams = 400 ÷ 9 = 44.4g
Final Result:
- Protein: 150g
- Carbs: 250g
- Fat: 44.4g
