More and More Stupid Fat Overweight and obesity alias can not only dangerous to health because it can be a risk factor for heart disease, stroke and diabetes, but also can make your thinking ability decreases. The more fat, brain volume decreases. Research recently conducted American scientists conclude that the brains of people who are overweight (obesity) will begin to deteriorate when it reaches the age of 40 years. In that study, scientists involved participants who varied with age range 40 to 60 years. Participants were divided into three groups based on body weight, normal, overweight (overweight) and obesity (overweight). The three groups of participants were asked to solve complex problems and his brain activity measured using magnetic resonance imaging (MRI). Results from the settlement of the problem indicates there is little difference in the participants of the three groups, but the image of MRI showed a decreasing function of the parietal lobe of the brain a significant part in the obese group. Scientists say the gray matter (gray areas) in obese people (obese) reacted differently to tasks that are regulated as compared with those with normal weight. In addition, the level of brain atrophy is directly associated with Body Mass Index (BMI). The researchers also showed that people with excess body weight had been developed atrophy (shrinkage of cells) of brain tissue in several areas at once, ie frontal lobe, hippocampus, frontal callosal convolution and others. When compared to people with normal weight, brain volume of people who are obese 8 percent smaller, as reported by GeniusBeauty, Saturday (05/03/2011). The report in the journal Health from other scientific studies also indicate that obesity increases the risk of weakening the ability to think with age. While a study in 2009 conducted by the University of Pittsburgh found that the brains of people who are overweight (overweight) will experience a depreciation of 4 percent, while those who are obese (above overweight) will experience brain shrinkage by 8 percent. Sudha Seshadri, MD, a professor of neurology at Boston University School of Medicine, said the cause of this problem is the fat in the abdomen, also known as visceral fat (visceral fat). The results of this study have been published online in 2010 in the Annals of Neurology. "The greater the amount of visceral fat a person has to make his brain getting smaller. A small brain volume is associated with reduced cognitive functioning person," said Sudha Seshadri, MD.
