You can drink water during most types of fasting, especially intermittent fasting. Water does not affect blood sugar or insulin levels and contains zero calories, so it doesn't break the fast. In fact, drinking water is encouraged to stay hydrated, reduce hunger, and support digestion during fasting periods. The main exception is dry fasting, which prohibits all food and liquid intake, including water, for a designated time. Dry fasting carries health risks such as dehydration, so it should be done only under medical supervision. In summary:
- During intermittent fasting and most fasting types, drinking water is allowed and recommended.
- During dry fasting and some religious fasts (e.g., Ramadan or Yom Kippur), water is not permitted during the fasting hours.
- Water helps with hydration, hunger control, and overall well-being while fasting.
Therefore, unless you are doing dry fasting or fasting for specific religious reasons that forbid water, you can and should drink water while fasting.
