If you look at the MRI image of the brain, you will generally know if the person is obese or not

Whether the human body tends to be obese or not can be judged by BMI which is calculated by dividing body weight (kg) by the square of height (meters). From the latest research on the brain, it is becoming clear that there is a certain correlation between the value of BMI and the structural features of the brain.

Study Suggests Link Between Obesity, the Brain, and Genetics

This study was conducted by a research team of the University Hospital of Canada Montreal Neurological Institute and Hospital (The Neuro). Project to conduct research on the human brain The relation between BMI and the brain was investigated by using MRI data of 1,200 brains collected in the Human Connectome Project .

The results of the survey have revealed that those with high BMI tend to be decreasing in "cognitive flexibility", "ability to delay satisfying desire", "visual spatial ability" and "linguistic memory" It was said that it was a fact. In addition, those with high BMI have a tendency that the left prefrontal cortex is thicker, while the right prefrontal cortex is diluted. Previous studies have confirmed that people who have been damaged by the right prefrontal cortex increased their appetite.

In addition, those with high BMI are suspected of having a large volume of the left amygdala of the brain that is thought to be responsible for food responses, as well as the "inner olfactory / hippocampal hippocampal structure" associated with episodic memory and context processing It is also clear that the volume is relatively small.

From these situations, people with a high BMI (= people with a tendency to obesity) are more sensitive to food and predict the negative situation (= weight gain) caused by eating to resist resistance to appetite The situation that it is not good at doing is highlighted. In addition, many of the subjects were siblings related in relation to each other, and since the twins were included in them, the research team succeeded in calculating the hereditary possibility of obesity using BMI. Using statistical methods, the research team revealed that many of the cognitive and neurological features have a genetic association with obesity.

Uku Vainik, the principal author of the thesis and a researcher at The Neuro and the Institute of Psychology in Tartu University in Estonia, said, "This study is extremely helpful in researching intervention methods to help people in obese states It will be something, "suggesting the possibility of creating a new way to eliminate obesity.

Also, Professor Alain Dagher, a medical professor at McGill University to which the university hospital The Neuro belongs, commented, "This study focuses on human weight control under the control of a relatively high level of brain function including cognition, decision making, motivation "It states that it is related to obesity and brain function. And furthermore, "The solid difference in the brain system that controls the intake of foods seems to be mildly hereditary", suggesting that the height of BMI has certain heritability doing.
