Abstract: Compositions are provided comprising a balance between lysine and essential amino acids and metabolizable energy. The compositions are useful in methods to prevent or treat obesity in an animal without concomitant loss of lean muscle mass. The compositions may also be used in methods to preserve or to cause a gain in lean muscle mass in an animal in need thereof.

Abstract: The present invention provides animal food compositions comprising high quality proteins and highly digestible carbohydrates which result in reduced stool production and stool odor upon ingestion by an animal, and methods for use.

Abstract: A food composition that is useful for increasing antioxidant levels in the body is provided having increased levels of sulfur-containing amino acids, such as methionine, cysteine, or mixtures thereof. Methods of using these compositions for increasing antioxidant levels in the body in mammals, especially in companion animals, are also provided.

Abstract: A method to measure enhancement in the quality of life of an animal fed a super senior pet food composition comprising quantitating the gene expression levels of one or more genes in said animal and comparing said levels in the animal to levels in the animal prior to administration of said super senior pet food composition. A method to enhance the quality of life of an animal by modulating the expression level of one or more genes in said animal in order to mimic the pattern of expression seen in vivo after administration of a super senior pet food composition.
