What physiological changes may adolescents experience that affect their nutritional needs?

Adolescents undergo a variety of physiological changes that significantly impact their nutritional needs, particularly highlighted by significant physical growth and changes in body composition. During this developmental stage, adolescents experience growth spurts that require increased caloric intake to support the energy demands of growing bones, muscles, and overall body mass. This also includes changes in body composition, as adolescents often gain lean muscle mass, which increases their metabolic rate and nutrient requirements.

These physiological developments necessitate a careful consideration of nutrient intake, particularly in proteins, vitamins, and minerals, which play critical roles in growth and development. Additionally, the demands of increased physical activity typical in adolescence further amplify the need for proper nutrition to support both performance and overall health.

In contrast, options reflecting decreased energy needs, constant metabolic rates, or increased hormonal stability do not align with the typical adolescent experience, as energy requirements and metabolic rates typically increase during this time due to rapid growth and activity levels.
