Abstract: Disclosed herein are methods of using glucose anti-metabolites to alter utilization of glucose or other energy sources and to mimic metabolic effects of caloric restriction. In particular, in one embodiment herein, methods of enhancing longevity in an animal are described, the methods comprising administration of a composition comprising a glucose anti-metabolite to the animal. In another embodiment, methods of enhancing longevity in an animal are described, the methods comprising administration of a composition comprising avocado extract, wherein the avocado extract comprises mannoheptulose. In yet another embodiment, methods of enhancing longevity in an animal are described, the methods comprising administration of a composition comprising mannoheptulose.

Abstract: A method of obtaining beneficial biological results associated with caloric restriction may be gained by administration of a composition containing at least one active agent which blocks metabolism of glucose as a source of energy in cells in glucose metabolism blocking effective amounts to an animal in need thereof.

Abstract: A process and composition for controlling fecal hair excretion and trichobezoar formation in animals such as cats and rabbits is provided and includes feeding the animal a composition comprising from about 10 to about 42 wt % crude protein, from about 4 to about 30 wt % fat, from about 1 to about 25 wt % total dietary fiber, and a supplemental fiber source. The supplemental fiber source is present in amounts which provide from about 1 to about 13 weight percent of supplemental total dietary fiber. The animal is maintained on the diet for a sufficient period of time to control fecal hair excretion and trichobezoar formation.

Abstract: A process is provided for reducing adiposity in an animal such as a companion animal by feeding the animal an effective amount of Vitamin A for a time sufficient to reduce adiposity in the animal. Preferably, the such effective amount comprises from about 50,000 IU to about 1,000,000 IU of Vitamin A per kilogram of diet. Such an effective amount provides sufficient Vitamin A to decrease accumulation of body fat, increase UCP1 levels, and decrease serum leptin levels in the animal.

Abstract: Disclosed herein are pet food compositions. In one embodiment, pet food compositions which are described comprise a component selected from 2-deoxy-D-glucose; 5-thio-D-glucose; 3-O-methylglucose; 1,5-anhydro-D-glucitol; 2,5-anhydro-D-mannitol; mannoheptulose; and mixtures thereof. In yet another embodiment, pet food compositions which are described comprise an extract of plant matter selected from avocado, alfalfa, fig, primrose, and mixtures thereof. The pet food compositions may be prepared by any of a variety of processes including, but not limited to, optional processes described herein.
