Q: A person consumes 60 grams of carbohydrates, 20 grams of protein, and 10 grams of fat in a meal. Calculate the total energy intake from this meal in kilocalories ($$kcal$$), using the following energy values: carbohydrates = $$4\ kcal/g$$, protein = $$4\ kcal/g$$, fat = $$9\ kcal/g.$$

$$60 \times 4 + 20 \times 4 + 10 \times 9 = 240 + 80 + 90 = 410\ kcal$$
