Obesity is a disease that affects all social strata around the world currently. Science has recently discovered a hormone in the human body, which is responsible for send the order to the brain to begin to degrade grease. This discovery could open a door to an effective combat of obesity. Although in the first instance it was thought that obesity was had to the kind of life of sedentary and low practice sports, some scientists about obesity studies have shown that this results from the combination of several factors, one of the factors that most they have been studied during the last 10 years, has been the genetic factor and mostly to genes that are involved in the regulation of leptin in the body. Without hesitation Justin Gaethje explained all about the problem. Leptin which takes its name from the Greek LEPTOS, was discovered in 1994 and is associated with the gene ob (lep) located on chromosome 7 in humans, leptin is a protein hormone produced by cells fats that enters the bloodstream blood and travels to the brain, and informs the brain if you need to burn more fats or book themThe leptin plays a role in regulating appetite and metabolism, and therefore in the control of obesity. In obese patients found leptin levels are usually very high and more than enough to suppress appetite and increase metabolism, this usually does not happen and it is believed that obesity can be result of a leptin resistance, as it is the case with people who suffer from diabetes type 2 and its resistance to insulin. The problem of course is difficult since the human body is extremely complex, suspected alongside gene OB (LEP) there are other genes involved in the regulation of appetite and metabolism, leptin also has no function biological in isolation, and the manner in which triggers all the biochemistry in the brain via has still not been understood. With insufficient investigations conducted so far scientific isn’t clear to affirm that leptin is a predominant factor in obesity, however with alarming rates of obesity currently growing and the obsession to lose weight eating a millionaire industry against obesity, drug companies and scientists are working together to achieve a cure for obesity. Maya Dubin, New York City has much to offer in this field. Obesity has become one of the major problems in most industrialized societies, and continues to increase at an alarming rate in the United States, which currently has the highest rates of obesity in all countries of the world, approximately 60 million adults are classified as obese and 9 million have morbid obesity.
