A 12‑year‑old boy weighs 45 kg, is 150 cm tall and is 13 years old. His basal metabolic rate (BMR) can be estimated by the equation \( \text{BMR}=66 + (13.7 \times \text{weight}) + (5 \times \text{height}) - (6.8 \times \text{age}) \) (kcal/day). He engages in moderate‑intensity activity, for which an activity factor of 1.6 is applied.\n\n(a) Calculate his total daily energy expenditure (TDEE).\n(b) If his diet supplies 55 % of calories from carbohydrates, 30 % from protein and 15 % from fat, determine the number of grams of each macronutrient he should consume per day. (Use 4 kcal g⁻¹ for carbohydrate and protein, and 9 kcal g⁻¹ for fat.)

Answer Options

A. TDEE ≈ 2300 kcal/day; Carbohydrate ≈ 320 g, Protein ≈ 170 g, Fat ≈ 38 g
Correct Answer B. TDEE ≈ 2151 kcal/day; Carbohydrate ≈ 296 g, Protein ≈ 161 g, Fat ≈ 36 g
C. TDEE ≈ 2000 kcal/day; Carbohydrate ≈ 275 g, Protein ≈ 150 g, Fat ≈ 33 g
D. TDEE ≈ 1900 kcal/day; Carbohydrate ≈ 260 g, Protein ≈ 140 g, Fat ≈ 30 g
Correct Answer
B
Correct Option:
TDEE ≈ 2151 kcal/day; Carbohydrate ≈ 296 g, Protein ≈ 161 g, Fat ≈ 36 g
