Abstract: A portion of a natural sponge is compressed into a capsule which can be swallowed. The capsule dissolves in the stomach, allowing to sponge to expand and fill a substantial portion of the stomach to give a feeling of fullness and to suppress the appetite. Nutritious foods and dietary supplements may be consumed contemporaneously. The sponge portion, which passes through the human body without being dissolved, may be cleaned and reused. Another portion of natural sponge may be kept in the mouth to promote salivation and improve digestion.
