Which of these groups typically require more than two thousand calories a day?

Teen boys typically require more than two thousand calories a day due to several factors associated with their growth and development. During adolescence, boys experience significant physical growth, which includes an increase in muscle mass and height. This developmental stage demands a higher caloric intake to support their energy needs for daily activities, sports, and the biological processes involved in growth.

In addition to physical growth, active teenage boys often engage in sports and other vigorous activities that further increase their energy requirements. The calorie needs can vary based on activity level, with more active boys requiring upwards of 3,000 calories or more to maintain a healthy balance of energy consumption and expenditure.

Comparatively, older men, adult women, and children generally have lower caloric needs depending on their age, size, activity level, and metabolic rate. While some older men may require higher calories, it is not as consistent across all such individuals as seen in adolescent boys. Adult women, particularly those who are not physically active, typically have lower energy needs. Children’s calorie requirements can vary significantly based on their growth stage and activity but generally fall below that of teenage boys.
