Water fasting is a type of fasting where individuals consume only water for a specific period, typically ranging from 24 hours to several days. This practice is often used for detoxification, weight loss, or spiritual reasons. During this time, the body relies on stored energy and nutrients, which can lead to various physiological changes. While water fasting can have potential benefits, it may also pose risks, especially for those with underlying health conditions. It's essential to consult a healthcare professional before starting a fast to ensure safety and to understand the possible effects on the body.
