A study at Montreal University has discovered a slimming pill that will tell the body to stop eating. The new slimming pill tells the brain that you are full and that your body doesn't need anymore food or calories.

The new weight loss and dieting pill contains leptin, a hormone produced by the body naturally that signals a person is full and doesn't need to eat more.

During the study mice were deprived of leptin, which lead to the mice eating so much they struggled to move around. Leptin has been proved to be a natural appetite surpressant when injected, but through the Canadian study, it is now believed that same weight loss success rate would occur if a slimming pill was taken orally.

Other research has shown that lack of sleep reduces the levels of leptin in the body, meaning that lack of sleep, and reduced levels of leptin can drive the appetite and lead to increases in weight and body fat.
