Japanese diet glasses

Japanese diet glasses are one of the newest innovations in weight-loss tips, aids and boosters- relying on our sense of sight to inhibit food intake. The diet glasses out of Japan are, on one hand, a totally risk-free way to eat less and lose weight. They are, however, a bit silly.

Researchers at the University of Tokyo developed the Japanese diet glasses as a drug-free way to get people trying to eat less to perceive meals as larger and more satisfying when wearing the devices.

 On one device goggle-mounted cameras send images to a computer, which magnifies the apparent size of the cookie in the image it displays to the wearer while keeping his hand the same size, making the snack appear larger than it actually is. In experiments, volunteers consumed nearly 10 percent less when the biscuits they were eating appeared 50 percent bigger.

They ate 15 percent more when cookies were manipulated to look two-thirds of their real size.
