Devices send alert when eating too much

The intelligence of humans has never come to a blind alley when used in developing new devices to fight obesity.

Scientists at the University of California, Los Angeles, have developed a smart necklace equipped with a sensor which uses vibrations in the throat to monitor food and drinks consumed and send an alert if too much has been ingested.

Another new way to treat obesity, already approved by the Food and Drug Administration, requires the surgical implantation of a small 'anti-obesity' device into the stomach which promotes earlier feelings of fullness by blocking nerves between brain and stomach.

But the surgical implant that shuts down the biological instinct to eat may bring side effects including nausea, pain, vomiting and surgical complications.
