The promising results of an experiment at Krakow's historic Jagiellonian University School of Medicine suggest that the end of obesity could be just a brain-wave away, DPA reported. "You're not hungry! You're not hungry!" This simple impulse, sent to the brain by an electrode implanted at its base, has seen two obese patients begin slowly but surely to shed excess kilos, according to a report in Thursday's edition of Poland's mass circulation Gazeta Wyborcza daily. Simpler and safer than a stomach staple, liposuction or crash diets, the fat-fighting electrode is the brain-child of Krakow doctor Jacek Sobczak. Initial tests are being carried out on a woman and man who both weighed-in respectively at a hefty 120 and 130 kilos. Since the electrodes, which have an on-and-off switch, were implanted on January 12 the patients are able to switch them on when they get up in the morning and enjoy the day without the obsessive need to gobble down everything in sight, physicians say. As a result the kilos are melting away. More experimental implants on several other patients are planned in the coming days and weeks.
