Medical researchers in Sydney have developed a new weight loss drug which, the developers claim, works by changing the way the body uses fat by interfering with the signals send by the brain to the body. The scientists at the Garvan Institute of Medical Research tested the drug on laboratory mice and discovered that it has the potential to curb weight gain by stopping the brain's signals.

Traditionally, weight loss medicines work by interfering with and curbing the hunger signals that the brains send to the body. But experts involved in the study are now asserting that this method seems to be ineffective, especially the Head of the Neurosciences Program at Garvan, Professor Herbert Herzog, who stressed, "What we've found is that blocking one system that influences appetite and body weight regulation might not be enough to cause a significant change in reducing body weight. If you take one signal away, others take over".

The new drug which will be ready for human trail in about three years, is also said to help the body work towards burning more fat.

In the laboratory mice that the drug was tested on, scientist found a loss of weight and body fat, but muscle mass was unaffected.
