Final answer:
To calculate the total calories in a diet, you need to multiply the grams of each macronutrient (carbohydrates, protein, fat, and alcohol) by their respective calorie values. Carbohydrates and protein provide 4 calories per gram, fat provides 9 calories per gram, and alcohol provides 7 calories per gram.
Step-by-step explanation:
To calculate the total calories in a diet, we need to multiply the grams of each macronutrient (carbohydrates, protein, fat, and alcohol) by their respective calorie values. Carbohydrates and protein provide 4 calories per gram, fat provides 9 calories per gram, and alcohol provides 7 calories per gram. Let's calculate:
Carbohydrates: 200 g x 4 calories/g = 800 calories
Protein: 150 g x 4 calories/g = 600 calories
Fat: 102.3 g x 9 calories/g = 920.7 calories
Alcohol: 14 g x 7 calories/g = 98 calories
To find the total calories, we add up the calories from each macronutrient: 800 + 600 + 920.7 + 98 = 2418.7 calories.
