How a tiny tummy patch could cut fat fast, and without exercise - (National Post via NewsPoints Desk)

  • A study published in the journal Small Methods suggests that a tiny patch used on mice that were fed on a high-fat diet reduced body fat by 30 percent in 28 days without the need to exercise, as reported National Post Tuesday.

  • The patch, which costs around 2.50 pounds to produce, is covered in hundreds of microneedles that gradually deliver a beta-3 adrenergic receptor agonist and a thyroid hormone called T3 triiodothyronine.

  • According to the news source, the patch is pressed into the skin for approximately two minutes, causing the micro-needles to become embedded in the skin after which the patch can be removed.

  • As the micro-needles degrade, the drug molecules slowly diffuse the white fat underneath the skin, turning it into brown fat.

  • The scientists reportedly want to move to clinical trials quickly and have received interest from several biotech companies who wish to develop the device.

  • Xu Chenjie, assistant professor at Nanyang Technological University, where the study was completed, said that "with the embedded microneedles in the skin of the mice, the surrounding fats started browning in five days, which helped to increase the energy expenditure of the mice, leading to a reduction in body fat gain."
