carbohydrates. What is the energy value of this meal?
A) 150 kcal
B) 170 kcal
C) 190 kcal
D) 210 kcal
Correct Answer: B) 170 kcal
Rationale: Protein provides 4 kcal/g (8g × 4 = 32 kcal), fat provides 9 kcal/g (10g ×
9 = 90 kcal), and carbohydrates provide 4 kcal/g (12g × 4 = 48 kcal). Total: 32 + 90 +
48 = 170 kcal.

D) 110 grams
Correct Answer: C) 100 grams
Rationale: 1600 kcal × 0.25 = 400 kcal from protein. Since protein provides 4
kcal/g: 400 ÷ 4 = 100 grams.
