Our friends over at Engadget tipped us off to a really unusual diet-helper called the Smart Plate. The 15-cm plate was invented by a Ukrainian scientist, Dr. Hryhory Chausovsky, and is weight sensitive. When the plate is overloaded with food, a palm sized computer attached to the plate is activated and audio alerts are triggered. At that point, acting like your own personal "weight-watcher," the plate will reprimand the user, saying things like, "Stop right there! And what about excess weight?" and "Where's your willpower?" If you really have a problem with overloaded your plate, especially in a buffet-type of situation, it would be worth getting a few odd looks as you pulled out your own dish if it helped you keep your diet under control. And having your plate reprimand you in public is significantly more embarrassing than just bringing out the plate itself, so there is a good chance that the plate really would keep you on track.

Dr. Chausovsky has a number of other weight-loss aids to his name, too. He has a second version of the plate that has a different type of sensor. This one will play music faster and faster, depending on the speed at which food is eaten and the rate at which utensils touch the surface of the dish. Slower eating would keep the music at a normal tempo. He also has a belt that monitors a stomach's expansion during a meal, an armband that monitors calorie intake per bite, a refrigerator magnet that demands"Are you here because you are really hungry, or is it just your emotions?" when the door is opened and "food spectacles" that are tinted to make good food look unappealing.

Chausovsky says that he doesn't take any money for any of his inventions, since he got into the business to benefit people, not to profit from them.
