A generalized goal is to drink approximately 64 ounces per day. This number depends on your height, weight, age and activity level. Initially you can expect to feel full from a few sips of water or clear liquids. During the phase I or liquid diet try to consume 4 ounces every hour. This would be approximately 1 ounce every 15 minutes. As the diet advances increase you can increase your intake to between 6 and 8 ounces every hour. Remember that you have to separate your liquids from your solids. It may be helpful to create a schedule and keep a food diary so you can review your daily intake. It is a good idea to carry a water bottle with you at all times to make sure that you are meeting the goal.
