How long does the body have with no fluid or food intake and what are the stages?

The human body can typically survive without food for about 1 to 2 months, depending on individual factors like fat reserves and overall health. However, without water, survival is generally limited to about 3 to 7 days. During the initial stage of fasting, the body uses glycogen stores for energy, followed by fat breakdown, and eventually muscle protein. Dehydration stages can lead to symptoms like fatigue, confusion, and eventually organ failure if fluid intake is not restored.
