| Abstract: |
An oral weight control apparatus and method adapted to block solid foods from entering the stomach of a user thereof, while at the same time allowing the user to freely move his tongue and jaws, to talk, to breathe, to drink fluids, and to participate in other desirable activities without the presence of the apparatus being visible or otherwise made known to anyone other than the user. The apparatus includes a guard, net, or other sieve-like blocking means that is secured inside the mouth of the user. Liquids and finely ground foods may freely pass through the guard or sieve but solid foods may not. In the preferred embodiment, the blocking means functions as a one-way valve, blocking solid foods from entering the stomach through the mouth but allowing food within the stomach to pass back out through the mouth (as would occur, for example, during regurgitation). The method includes mounting such an apparatus within the mouth in order to constrain the user to follow a suitable diet comprised of liquids and finely ground foods having a desired nutrient level.

What is claimed is:
1. An oral weight control device for impeding the eating process and slowing down the rate of food consumption to thereby allow the body time to naturally register the sensation of being full prior to completion of a meal, said device comprising:
- an upper support member adapted to be secured to the inside back of the user's mouth;
- a sieve-like guard pivotally coupled in vertical orientation to the support member to allow the guard to raise and lower in response to movements of the user's tongue, said guard having meshed openings therein of a selected size to impede the otherwise unobstructed passage of large food particles;
- said guard including means for positioning a bottom edge thereof at a part of the mouth forward of the support means and near the user's tongue when the device is properly located within the mouth;
- said pivotal attachment providing means for displacement of the guard into a substantially nonblocking position in response to emergent food, thereby preventing possible choking from regurgitated food material.
