How long can a person live without nourishment?

A person can typically survive without nourishment for about 1 to 2 months, depending on various factors such as body fat, hydration levels, and overall health. The body initially uses stored carbohydrates and fats for energy, but eventually, it will start breaking down muscle tissue. Hydration is crucial, as survival without water is generally limited to about 3 to 7 days. Individual circumstances can vary widely based on factors like age, health, and environmental conditions.
