Q: Calculate the total energy intake (in kcal) for a meal containing 50g carbohydrates, 20g protein, and 10g fat. Use the following values: $$4 \text{ kcal/g}$$ for carbohydrates, $$4 \text{ kcal/g}$$ for protein, $$9 \text{ kcal/g}$$ for fat.

$$(50 \times 4) + (20 \times 4) + (10 \times 9) = 200 + 80 + 90 = 370 \text{ kcal}$$

Q: A nutrition label states that a food contains 8g fat, 25g carbohydrate, and 5g protein per serving. Calculate the total energy per serving using the appropriate energy values for each macronutrient.

$$(8 \times 9) + (25 \times 4) + (5 \times 4) = 72 + 100 + 20 = 192 \text{ kcal}$$
