American scientists found out how nicotine inhibits the appetite by switching off the receptors responsable for appetite and food intake. The results of the research were published in Science.

Scientists discovered that smoking creates an anorexic effect in particular parts of the brain in mice. The discovery may help to create nicotine-based therapy to fight both smoking addiction and obesity in humans.

The author of the study, Yann Mineur from Yale School of Medicine, says though all that is basic biology and some processes are similar to mice and humans, but it is necessary to be extremely careful and make more studies in this direction.

These days smoking is one of the preventable causes of a number of diseases in many countries of the world. Smoking has shown to help in losing weight. Most smokers are generally thinner than non-smokers. People who quit smoking often do gain weight and that is the reason why people do not want to refuse from cigarettes.

A lot of studies previously have attributed the effects of smoking on the appetite to nicotine, but only now they found out how nicotine affects food intake parts of the body which leads to weight loss.

Mineur with his team discovered how exactly nicotine receptors affect the central nervous system which results in appetite loss and futher weight loss.

All the experiments were made on mice. The results of these experiments helped scientists to find out the way nicotine influences body’s hypothalamic melanocortin system by activating certain receptors.

Does it mean that these properties of nicotine could be used to fight obesity? The latest findings will help to find ways to control weight during quitting.
