Starvation: How Long Can the Human Body Last Without Food?
The length of time a person can survive without food varies based on individual factors like health, body composition, hydration, and environmental conditions. Typically, a healthy individual can endure several weeks without food, using fat stores and muscle mass for energy. However, hydration is critical as dehydration can lead to rapid decline and potentially be fatal within days. The body enters ketosis, utilizing fat for fuel, but prolonged food deprivation can cause severe complications like organ failure and weakened immunity. These situations require caution and medical supervision.
