The Mathematical Formula
Total Calories = Σ (Food Calories per 100g × Serving Size / 100)

Calories are calculated from macronutrients:

Calories = (Protein × 4) + (Carbohydrates × 4) + (Fat × 9)

Where: - Protein provides 4 calories per gram - Carbohydrates provide 4 calories per gram - Fat provides 9 calories per gram - Alcohol provides 7 calories per gram

Daily Values (2000 calorie diet): - Protein: 50g - Carbohydrates: 300g - Fat: 65g - Saturated Fat: 20g
