The premise of the Michitaka Hirose Diet Goggles is that people will eat less of something if each portion looks to be extremely large. Essentially, these glasses magnify food relative to the wearer's hand.
This University of Tokyo professor has created glasses that use computer technology to artificially enlarge an Oreo so that it either grows or shrinks in size, relative to the hand. Tests show that people will eat ten percent less when the Oreo is grown 50 percent more. The technology is still in its infancy, as it is not capable of handling irregularly shaped foods like bananas just yet.
These goggles are a promising breakthrough to dieting into the future as there is no food restriction or vitamin prescription.
