Abstract: A dry nutritional meal replacement composition based on the formulation comprising inter alia a protein blend comprising protein concentrate in an amount of about 4.0-86.0% by weight; a blend comprising a cellulose gel and carboxymethyl cellulose gum in an amount of about 2.3-93.0% by weight; a vitamin blend in an amount of about 0.1-12.0% by weight; a mineral blend in an amount of about 0.1-19.0% by weight; a natural or artificial sweetener in an amount of about 0.1-80.0% by weight; dietary fibers other than the cellulose blend in an amount of up to about 66% by weight; and an effective amount of a flavoring agent, alone, or in combination with a coloring agent. The composition, when mixed with an ingestable liquid, such as milk, and shaken at low shear forms a shake, and when mixed at high shear forms a mousse. When ingested, the mixed composition elicits satiety and can be used as a total meal replacement without adverse gastrointestinal disturbances.
