A fat-binding composition contains an inclusion complex with a host molecule and a guest molecule. The guest molecule includes one or more amino acids, vitamins, flavorants or related compounds, rutin, betanin derivatives thereof, and mixtures thereof. The fat-binding composition may be in the form of a tablet or powder, for example, and may be incorporated into a food or beverage product. If in the form of a powder or tablet, the composition may optionally contain a carbonation-forming component and may be dissolved in carbonated or non-car-bonated water. The fat-binding composition may also be employed in a method for binding fat ingested by an animal which includes having the animal ingest the composition, or a food or beverage product containing the same.
