Vibrating Pill May Give Dieters a Feeling of Fullness, Study Suggests

Scientists have developed a vibrating pill that, when swallowed before eating, can create a feeling of fullness. The Guardian reports: The research, which has yet to be carried out in humans, shows that after 30 minutes of activity by the Vibes pill, pigs ate on average almost 40% less food in the following half hour than they did without the device, and gained weight more slowly. The Vibes name is an acronym derived from the pill's full title -- Vibrating Ingestible BioElectronic Stimulator. The work in pigs suggests the vibrations activate stretch receptors in the stomach, simulating the presence of food. This results in signals being sent to the hypothalamus in the brain via the vagus nerve, increasing levels of various hormones that give rise to a feeling of fullness and decreasing those that result in feelings of hunger. "We envision the Vibes pill being ingested on a relatively empty stomach 20 to 30 min before anticipated meals to trigger the desired sensation of satiety early in the meal,a the team write, adding that when produced at scale, the cost of the pills is expected to be in the cents to one dollar range. The vibrations, which are powered by a battery encased in the swallowed capsule, can be triggered when stomach acid dissolves a membrane around the pill, or by a timer. The researchers say the pills, which are about the size of a large vitamin tablet, offer a non-invasive, temporary therapy, without the need for weight-loss surgery, and exit the body with other solid waste -- meaning in humans they are flushed down the toilet. However they suggest it could be possible to develop pills that are implanted, or stay in the stomach, to reduce the need for people to repeatedly take them, should they require continuing therapy.
