According to recent research, foods with high fat content, but the nutritional value of zero can damage cells in the brain that controls body weight and obesity lead to cycles. These findings also explain why people who are overweight are so difficult to lose weight.
In his research, experts from the University of Washington gave the rats in the laboratory with the type of food which they call "high-fat diet of the American people". Only three days later, the rats are getting greedy and increase calorie intake until doubled.
Further examination showed that these mice also experience inflammation or inflammation of hypothalamus, the brain consists of nerve cells that control body weight. Inflammation was stopped within a few days, but then "relapsed" after four weeks later.
Dr. Joshua Thaler, expert and researcher of Diabetes and Obesity Center of Excellence at the University of Washington in Seattle, said the experts also detect the presence of a brain injury recovery response called gliosis.
"Gliosis considered together with the recovery of injuries to the brain, and specifically looks at the conditions of nerve injury, such as stroke and multiple sclerosis. We speculate that gliosis that we might see as a protective response that failed. We also detected a significant damage and loss of cell nerve cells are important in controlling weight, "said Thaler, who presented his research at the annual meeting of The Endocrine Societys for-93 in Boston.
He added that possibility of injury in rat brain is a consequence of excessive consumption of junk food and this fact gives an explanation of why losing weight becomes very difficult for most of them are obese.
