How do puberty-driven growth spurts primarily change macronutrient requirements compared with earlier childhood?

• A. They lower carbohydrate needs because adolescents become more insulin sensitive during puberty and therefore require fewer carbs than younger children.
• B. They increase total energy needs and maintain similar carbohydrate proportions while protein needs move closer to adult per-kg recommendations and fat remains 25–35% of energy.
• C. They eliminate the need for increased micronutrient intake because growth is primarily soft-tissue and does not require extra vitamins or minerals.
• D. They drastically increase protein needs above adult levels requiring at least 2 g/kg body weight to support muscle and bone growth during adolescence.

Answer: (B)
