The experimental pill works in the same way as gastric pacemakers to suppress appetite. A gastric pacemaker is an implant that is surgically placed in the stomach and wired to the vagus nerve.
This nerve carries signals from the stomach to the hypothalamus, the area of the brain responsible for regulating appetite.
The pacemaker has a sensor that detects when food is entering the stomach. It then fires low-level electrical pulses into the vagus nerve to fool the brain into thinking the stomach has no more room.
Gastric pacemakers cost around £10, 000 and are reserved usually for patients who don't respond to dieting,
