When figuring energy needs for active adolescents, several factors drive how many calories the body uses each day. Growth requires extra energy to build new tissues. Puberty brings hormonal changes that can alter metabolism and energy needs. Activity level directly increases energy expenditure through movement and exercise. Body size influences metabolic rate—larger bodies typically burn more calories at rest and during activity. Climate affects energy needs because staying warm in cooler environments requires additional energy. Metabolic rate itself determines how efficiently the body uses fuel and can vary between individuals. Taken together, these factors provide a complete picture of what sets an adolescent’s energy needs. The other options miss multiple important pieces—for example, growth alone omits puberty, activity, size, climate, and metabolic rate; climate alone omits growth, puberty, activity, and size; sleep duration is not a primary driver of daily energy requirements for active teens.
