For purposes of this diet you would simply discard the fibrous material left over after juicing. What you want is the juice because that's where the highest concentration of vitamins & nutrients are which is what you're after with this diet. Once you're done you can use those leftovers for many things including making things like healthy snack chips and stuff. You won't need to add water to any of the juice as it's tasty just as it sits. Real juice before all the big $ corporations got a hold of the idea of juice and ruined it.
