What is the kcalorie value of a meal supplying 110g of carbohydrates, 25g protein, 20g fat and 5g alcohol?

Question

To determine the total kilocalorie value of the meal, I’ll calculate the energy contributed by each macronutrient and then add them together.
First, carbohydrates: 110 g at about 4 kcal per gram equals 110 × 4 = 440 kcal.
Next, protein: 25 g at about 4 kcal per gram equals 25 × 4 = 100 kcal.
Then, fat: 20 g at about 9 kcal per gram equals 20 × 9 = 180 kcal.
Finally, alcohol: 5 g at about 7 kcal per gram equals 5 × 7 = 35 kcal.
Now summing these contributions: 440 + 100 + 180 + 35 = 755 kcal.
Option a (160) is far too low, as it would require omitting nearly all macronutrient energy or using incorrect values, which contradicts standard Atwater factors.
Option b (345) underestimates the energy from carbohydrates and fat, not accounting for the full contributions calculated above.
Option c (560) combines partial sums that miss either the alcohol energy or some macronutrient energy, making it inconsistent with the full calculation.
Option d (755) matches the correct total energy when applying typical macronutrient energy values and summing them accurately.
