'Diet glasses' to stop overeating

Big eaters may be eyeing a cure to their overindulgent feeding habits.

Special goggles that trick them into thinking the healthy snack in their hand is actually a doughnut or makes biscuits appear larger than they really are have been on show in Japan.

Clever-clog researchers at the University of Tokyo have developed ‘diet glasses’ that use computer wizardry and augmented reality to fool the senses and make users feel more satisfied with smaller - or less appealing - treats.

Volunteers ate nearly 10 per cent less when the biscuits they were eating appeared 50 per cent bigger – but gobbled 15 per cent more when the cookies were manipulated to look two-thirds of their actual size.

While the goggles have yet to be commercialised, studies so far have shown 80 per cent of foodies tested said they were fooled.
