This invention relates to a nutritional dietary 
system, formulation, kit and method for use in preparing an individual for a predetermined activity which requires a clean 
digestive tract, particularly the colon. Such predetermined activities include, but are not limited to, gastrointestinal 
surgery and colon screenings. Specifically, the present invention provides an individual low amounts of fat, 
dietary fiber and 
solid food content to minimize stool formation and / or facilitate removal of stool from the 
digestive tract prior to the predetermined activity. The present invention also provides the individual with sufficient calories and 
nutrition to enable the individual to conduct daily, routine activities while utilizing the present invention. In one alternative embodiment, the dietary 
regimen of the present invention provides a variety of pre-packaged, 
ready to eat or easy to prepare nutritional liquid or 
solid foods which, when coordinated with a 
laxative regimen, result in removal of residue such that a medically and / or diagnostically useful procedure can be performed on the 
digestive tract.
