What is the maximum time the average person can survive without food?

The maximum time the average person can survive without food is generally considered to be around 30 days. This is based on various factors including the individual's health, hydration levels, and fat reserves. The body initially uses glycogen stores for energy, then transitions to fat and muscle tissue for sustenance.

After several days without food, the body starts to conserve energy and decrease its metabolic rate. While there have been extreme cases where some individuals have survived longer periods without food, these are not typical and often involve specific conditions. Thus, the rough average of around 30 days serves as a guideline for understanding human survival without food under standard circumstances.

Hydration also plays a crucial role in survival; without water, an individual may only survive a few days. Additionally, the other options suggest durations that either exceed known averages or do not align with physiological understanding of starvation, emphasizing that individuals generally cannot survive as long without food as these options propose.
