Smokers have lower body mass index: nicotine suppresses appetite

Researchers at Yale have found because of what people give up smoking more hungry and as a result, begin to gain weight. It is also able to understand how to cope with this phenomenon.

Large-scale studies have shown that on average, smokers do have a lower body mass index than people who are not touched cigarettes and tobacco, even taking into account factors such as diet, behavior and genetics.

The findings of one study even indicated that manufacturers specifically added to the tobacco mixture of substances that make smokers more slender, says Discovery. However, other experiments have shown that nicotine itself affects the brain in a way that suppresses the appetite.

Group Pichchotto Marina (Marina Picciotto) from the University of Yale decided to determine how this happens. Biologists conducted experiments with mice. After a month of experiments, "smoking" mice lost 15 to 20% of their fat reserves.

Later it turned out that nicotine binds to receptors that transmit information to the neurons in the hypothalamus, a brain region, in particular, hunger and sleep. Marina and her colleagues found that ultimately activates neurons, which are called cells proopiomelanocortin (POMC). It is their work leads to a decrease in appetite.

Also, scientists have determined that the substance cytisine (cytisine), often used in the treatment of nicotine dependence, acts in a similar way. In other experiments, animal biology, taking cytisine, eating less, but it was not clear for what reason.
