Abstract: Compositions and methods for inducing statiety and for reducing caloric intake having at least soluble anionic fiber and at least one soluble cation. The compositions may be solid, fluid, or mixtures thereof.

Abstract: An ingestible composition to increase viscosity imparted to the digesta in an intestine that includes a soluble anionic fiber and a protected cation. The protected cation may be coated with an enteric coating, a lipid coating, or a sustained release coating.

Abstract: Methods for inducing satiety, reducing food intake, and reducing weight in an animal by ingesting at least one soluble anionic fiber in the presence of a milk source.

Abstract: Ingestible compositions that include one or more anionic soluble fibers are provided herein. An ingestible composition can be in solid or liquid form. In certain cases, a solid ingestible composition includes an extruded food product, such as a crispy, that includes one or more anionic soluble fibers. Liquid ingestible compositions that can include one or more alginate anionic soluble fibers and one or more pectin anionic soluble fibers are also provided. Methods for making ingestible compositions are provided, as well as methods for using the ingestible compositions, e.g., to induce satiety or to increase the viscosity of stomach contents.
