Which family member has the highest daily calorie needs based on their activities?

The choice of Josh, aged 15, who participates in multiple sports, reflects an understanding of how physical activity levels influence daily caloric needs. Adolescents typically have heightened energy requirements due to growth, development, and increased activity levels.

Engaging in multiple sports demands a considerable amount of energy, not only for the physical exertion during practices and games but also for recovery and overall metabolic needs. This is particularly important during adolescence, a period marked by significant physical changes and growth spurts.

In contrast, while Jake, aged 17, working at a fast-food restaurant is certainly active, the nature of his job may not equate to the same level of cardiovascular and muscular exertion that can come from participating in various sports. Similarly, Amanda's and Karisa's activities are relatively less intensive when compared to the demands of playing multiple sports, which further supports the conclusion that Josh has the highest daily calorie needs due to his active lifestyle.
