Calorie Budget Calculator: calculate calorie budget for cooking and nutrition. Practical tips and worked examples.
Protein calories = Protein (g) × 4 kcal/g
Carbohydrate calories = Carbs (g) × 4 kcal/g
Fat calories = Fat (g) × 9 kcal/g
Alcohol calories = Alcohol (g) × 7 kcal/g
Total calories = Protein kcal + Carb kcal + Fat kcal (+ Alcohol kcal)
Worked example: 150g cooked chicken breast. Protein 46g (184 kcal), Carbs 0g, Fat 4g (36 kcal). Total = 220 kcal. Per 100g = approximately 147 kcal.
