A method by which one ensures maximum voiding of solid consumables, often to avoid adverse health effects from the matter consumed; i.e., consuming large amounts of fiber supplements immediately prior to and after a meal. The initial fiber intake provides the base, or "anvil," upon which the meal will rest. The final fiber intake, or "hammer," sits upon the meal. The resulting combined pressure of the "anvil" and "hammer" upon the meal, referred to as the "fiber vice," ensures effective and complete voiding of the meal to the subject's supreme satisfaction.
