A healthy 28-year-old moderately active woman has a calculated EER of 2,200 kcal/day. Her 4-day intake record shows total daily calories: Day1 2,300 kcal (CHO 55%, Fat 28%, Protein 17%), Day2 2,100 kcal (CHO 48%, Fat 32%, Protein 20%), Day3 2,250 kcal (CHO 60%, Fat 22%, Protein 18%), Day4 1,950 kcal (CHO 50%, Fat 30%, Protein 20%). Calculate her 4-day average calorie intake and analyze whether her average macronutrient distribution falls within the AMDR for each macronutrient. Provide brief justification.

• A. Average 2,150 kcal/day; Carbs 70% (exceeds AMDR), Fat 10% (below AMDR), Protein 20% (within); indicates insufficient fat intake.
• B. Average 2,400 kcal/day; Carbs 40% (below AMDR), Fat 35% (upper AMDR), Protein 25% (within); overall calorie surplus is likely.
• C. Average 2,150 kcal/day; Carbs 53.3% (within AMDR), Fat 28.0% (within AMDR), Protein 18.8% (within AMDR); overall appropriate distribution though slightly below EER.
• D. Average 1,900 kcal/day; Carbs 50% (within), Fat 20% (lower bound), Protein 30% (high); indicates significant energy insufficiency unlikely to meet EER.

Answer: (C)
