Food app clicks away chocolate-iced donuts

A game that trains the brain to avoid unhealthy food, such as cakes, biscuits and chocolate, can lead to "pain-free" weight loss and cut energy intake by more than 200 calories a day, scientists say.

Psychologists at the University of Exeter in Britain showed that fewer than 10 minutes a day of "brain training" using a game that takes away the "mental reward" of sugary and fatty foods reduces calorie intake.

Professor Natalia Lawrence's Food Trainer app is free and is being launched this month on Android devices.
