Normally, fiber is great for moving things through your system, but when the body must separate out juice from fiber, there is an energy expenditure there that is significant. For our purposes, we want to reduce this burden as much as possible so that we can give the body and digestive tract a break from having to break down solid food – so that the saved energy can be transferred to cleansing processes. When you save energy in one department you can expend it somewhere else.
