Roughly how many calories of stored energy as fat does the average adult human hold?

The average adult human stores a significant amount of energy as fat, which serves as a vital energy reserve for various bodily functions and physical activities. The correct answer indicates that an average adult can store approximately 130,000 calories of energy in the form of fat.

This figure is derived from the understanding that the body stores fat in adipose tissue, which varies widely among individuals depending on factors such as age, sex, genetic predisposition, and overall body composition. While these variations exist, studies estimate that the average adult, depending largely on body size and composition, typically holds around this amount of energy. This stored fat is crucial for maintaining energy balance, especially during periods of fasting or extended physical activity.

The other options represent values that are higher or lower than the expected average, which do not align with the commonly accepted estimates of fat storage in the average adult. Thus, the choice of 130,000 kcals is grounded in established research on human energy storage capabilities.
