Device and method of causing weight loss using removable variable volume intragastric bladder

A method and apparatus for causing weight loss in obese humans by occupying a segment of the stomach volume using a variable volume bladder filled with fluid. The bladder is inserted into the upper part of the stomach including the fundus through a percutaneous endoscopic gastrostony tube, which was non-surgically placed to create a permanent channel to the stomach. The inserted bladder is filled and emptied using a filling system for pumping fluid in and out of the bladder according to a predetermined scheme. The filling system comprises a reversible pump, a two-way valve connected to the filling tube, an electronic control means for automatically controlling the action of the filling system, and a battery. The electronic control means is connected to a plurality of sensors placed on the human body to detect digestion cycle and hemodynamic parameters. The electronic control means collects information detected by the sensors, governs the filling system according to the obtained information and predetermined operation scheme, and records times and volumes of the fluid transferred through the two-way valve.

Dietary compositions and method for promoting healthy weight loss cats

A dietary composition is provided for promoting healthy weight loss in cats which contains, on a dry matter basis, from about 0.2 to 1.5% by weight fatty acids selected from the group consisting of C18:3n3, C20:4n6, C20:5n3, C22:6n3, and mixtures thereof, and from about 28 to 50% by weight protein. The composition may be administered to obese cats to provide optimum weight loss while preventing hepatic lipidosis and other associated diseases.

Weight loss compositions and methods for individuals who may have gastric hyperacidity

Compositions and methods of losing weight are described that are suitable for individuals susceptible to gastric hyperacidity or gastroesophageal reflux. The compositions include in part a snack food having two or more rapidly digestible carbohydrates, in which the foodstuff or an aqueous mixture of the foodstuff and water has a pH equal to or greater than about 6, and in which the snack is substantially protein-free. The method of weight loss suitable for an individual with gastric hyperacidity includes substantially limiting the individual's caloric intake to about 1400 calories or less for women and 1800 calories or less for men in which the caloric intake includes one or more substantially protein-free snack foodstuffs having two or more rapidly digestible carbohydrates, in which an aqueous mixture of the foodstuff with water has a pH equal to or greater than about 6 and in which the individual loses weight.
