1. A method of controlling obesity, comprising the steps of positioning a sleeve impervious to digestive juices and normal foods in the digestive tract, arranging the sleeve in the digestive tract in such a manner that substantially all normally ingested food material passing naturally through the oral cavity and then passing through the digestive tract is caused to pass through the sleeve while being isolated from direct contact with the surrounding area of the interior walls of the digestive tract and body fluids secreted by such surrounding area interior walls such that natural absorption of food material in the digestive tract is impaired and a net caloric intake for a given quantity of ingested food is thereby reduced, said sleeve being disposed substantially entirely in the stomach.
