After 72 hours without food, the body enters a state of ketosis, where it begins to break down fat for energy due to depleted glycogen stores. Muscle breakdown may also occur as the body seeks protein for essential functions. Additionally, metabolic processes slow down to conserve energy, and hormonal changes can lead to increased fatigue, irritability, and cognitive decline. Hydration becomes crucial, as dehydration can significantly impact bodily functions during this period.
