The Floss Diet is] by definition is an innovative method in which dental floss is fashioned and self-administered as an oral restrictive device and behavior modification tool. You can use this oral device to have real and interactive support that helps moderate food intake. The floss restricts the opening between teeth.
Having a smaller opening requires smaller pieces of food to pass through, which slows down the ability to ingest food. As a result your brain can receive the signal that the stomach is full using less food and fewer calories.
