Abstract: A method of producing oncolysis and regression of malignant tumors and other malignant conditions without adverse effects on normal body cells is described. A calorically and compositionally defined nutritional regimen providing a minimum of amino acids and fatty acids and a maximum of carbohydrates is administered concurrently with a drug regimen of an agent or agents that uncouple oxidative phosphorylation, most preferably 2,4-dinitrophenol.

Abstract: An improved method is described for producing oncolysis, including regression of malignant tumors or other malignant conditions, without adverse effects upon normal body cells. In addition to a calorically and compositionally defined nutritional regimen providing a minimum of amino acids and fatty acids and a maximum of carbohydrate, administered concurrently with a drug regimen of an agent or agents that uncouple oxidative phosphorylation (most preferably 2,4-dinitrophenol), there is also concurrently administered a selected amount of a substantially non-toxic fatty acid oxidation inhibitor capable of effectively lowering the mitochondrial .beta.-oxidation rate of fatty acids.
