MojoKid writes: Psychologists at the University of Exeter and Cardiff University have published a study that demonstrates how a simple computer game can help people lose weight. Participants in the study who played the specialized game lost and average of 1.5 pounds in the first seven days, and 4.5 pounds after six months. They also reduced their daily caloric consumption by 220 calories. Dr. Natalia Lawrence led the team of researchers that developed the computer game for the study. It was designed to train people to resist unhealthy food snack foods through a “stop versus go” process. Participants sat in front of a Pentium 3 PC running Matlab software on a 17-inch monitor. They were then instructed to press certain keys when images of things like fruits and clothes would appear, indicating a “go.” But for images of calorie-dense foods (chips and cake, for example) they were instructed not to do anything, indicating a “stop” action.
