🧠 Example: Calculating Nutrition for Chicken Breast
Let’s say you want to calculate the nutrition for 150 grams of Chicken Breast.
| Nutrient | Per 100g | Input Value |
|---|---|---|
| Protein | 31g | 31 |
| Carbs | 0g | 0 |
| Fat | 3.6g | 3.6 |
| Cost | $1.20 | 1.20 |
Calculation:
- Grams Factor = 150 / 100 = 1.5
- Protein = 31 × 1.5 = 46.5g
- Carbs = 0 × 1.5 = 0g
- Fat = 3.6 × 1.5 = 5.4g
- Calories = (46.5×4) + (0×4) + (5.4×9) = 249.6 kcal
- Cost = $1.20 × 1.5 = $1.80
✅ Results:
- Total Protein: 46.5g
- Total Fat: 5.4g
- Total Calories: 249.6 kcal
- Cost: $1.80
