A new device to treat obesity has researchers buzzing about the possible implications. The device, known as the VBLOC, is attached to the vagal nerves in the abdomen. These nerves transmit signals of hunger and an empty stomach to the brain. The VBLOC blocks those signals, hopefully helping the person trying to lose weight feel full longer and eat fewer calories.

The VBLOC is seen as a safer alternative to gastric bypass and other weight loss surgeries. These surgeries, though effective, are extremely invasive and involve certain health risks. The VBLOC is less invasive in that there's no cutting of internal organs.

No one is sure yet if it will work, but the VBLOC is in human trials right now. The research team is looking for participants, so if you'd like to be part of their research study, follow the link for an application.
