The duration of a fast can vary significantly depending on individual health, hydration, and the type of fast. Generally, a person can safely fast for 24 to 72 hours without serious health risks if they stay hydrated. Some individuals have fasted for more extended periods, such as several days to weeks, but this should only be done under medical supervision. Extended fasting can lead to nutrient deficiencies and other health complications if not managed properly.
