Which factor is NOT listed as influencing energy needs for active adolescents?

• A. Growth, puberty, and activity level
• B. Body size and metabolic rate
• C. Climate
• D. Sleep duration

Answer: (D)

Energy needs for active adolescents are driven mainly by growth and puberty, how much they move, and their body size and metabolism. Growth and puberty push calorie needs higher to support tissue development, while activity level directly increases calories burned. Body size and metabolic rate set the baseline energy required at rest and during activity. Climate can shift energy needs a bit because extreme temperatures require more energy for thermoregulation, but its effect is usually smaller than that of growth, puberty, and activity. Sleep duration, while important for health and recovery, does not determine how many calories are needed to fuel growth and activity, so it isn’t listed as influencing energy needs.
