Additionally, children, the elderly, those who are breastfeeding, and people with chronic illness should not attempt a water fast. Day 1: Consume 1½ to 3 liters of water per day, spread out throughout the day. Three liters is about 12 8-ounce glasses per day, so you can break it down into 12 glasses of water throughout the day. Water will be the only thing you consume for the next 3-4 days. Day 2: Same as yesterday. Consume 1½ to 3 liters of water, spread out throughout the day. Day 3: Same as before. Consume 1½ to 3 liters of water, spread out throughout the day. Day 4: Here you can choose to end your water fast, or you can fast for one last day. If you continue your fast, consume 1½ to 3 liters of water, spread out throughout the day.
