It is a dietary regime created by Dr William D. Kelley. In Kelley's program, patients are evaluated to determine their individual physiological weaknesses. The regime is then designed to address the patient's requirements. They are put on a diet of juices, mostly raw foods, some cooked foods, and supplements consisting of mainly enzymes and grandulars. Dr Kelley placed a great deal of emphasis on the use of pancreatic enzymes, in higher doses than needed, just for protein metabolism. His program depends upon these enzymes to destroy the cancer cells. He viewed that cancer cells are essentially protein and therefore the patients needs the pancreatic enzymes to digest and metabolize the excess amount of protein.
