Show answer and rationale
Correct answer: B — For many people, caloric intake is more than needed for their physical activity.
The correct answer is B: "For many people, caloric intake is more than needed for their physical activity." This is a significant contributing factor to obesity in America. When individuals consume more calories than their body requires for energy expenditure, the excess calories get stored as fat, leading to weight gain and obesity. While cultural practices like eating at celebrations and holidays (A) and larger portion sizes in restaurants (D) can play a role, ultimately, the imbalance between caloric intake and physical activity is a fundamental cause of obesity. While the reduction in physical education requirements in schools (C) may impact overall physical activity levels, the primary issue lies in the excess calories consumed compared to what is expended through activity.
