When relying on stored glycogen for energy, how long can this energy last in an individual without liver disease?

Relying on stored glycogen for energy is a key aspect of how the body manages its energy resources, particularly during periods of fasting or increased physical activity. In a healthy individual without liver disease, glycogen stored in the liver can sustain blood glucose levels and provide energy for various bodily functions.

Typically, when the body is at rest or engaged in light activity, the stored glycogen can last from approximately 24 to 48 hours. This duration allows the body to maintain a stable blood glucose level and continue necessary metabolic processes before needing to tap into fat stores or consume new sources of energy.

Individuals with liver disease may experience altered glycogen storage and release capabilities, leading to different energy sustainability durations. Thus, in a healthy individual, the 24 to 48-hour timeframe reflects a normal physiological response to energy demands, making this the correct choice. The other options suggest shorter timeframes, which do not accurately represent the body's capabilities under normal conditions.
