Scientists have revealed that just by looking at the flickering screen could banish your hunger pangs, and so a broken TV or a TV that needs tuning could be helpful.
Food cravings seem to disappear instantly if someone spends just a few seconds at the black and white flickering screen. The volunteers who carried a hand held computer device displayed the flickering images and reported that their hunger pangs did subside by almost 23 percent immediately after they watched them.
During the course of the study, by psychologists at Flinders University in Adelaide, Australia, they also consumed nearly 40 percent fewer calories than participants who did not view the images.
The highly unusual dieting regimen deploys a technique known as dynamic visual noise, where thousands of tiny black and white dots bounce around the screen.
Scientists have been using dynamic visual noise in the laboratory for years, mainly to analyze how it affects short-term working memory.
But now research is beginning to show it can help people diet by blocking the vivid images that form in the brain when we experience sudden food cravings for treats like chocolate, ice cream or chips.
