Water is the most important thing to consume while you are fasting. Use these recommendations as a guideline for how much to drink:

Daily Water Intake Suggestions For Females:

• 4-8 years old – drink 1.7 liters of water per day
• 9-13 years old – drink 2.1 liters of water per day
• 14-18 years old – drink 2.3 liters of water per day
• 19+ – drink 2.7 liters of water per day

Daily Water Intake Suggestions For Males:

• 4-8 years old – drink 1.7 liters of water per day
• 9-13 years old – drink 2.4 liters of water per day
• 14-18 years old – drink 3.3 liters of water per day
• 19+ – drink 3.7 liters of water per day

While you are fasting, however, you will probably lose more water than usual, so you may need to drink an extra 2 cups of water in addition to the suggestions above.
