The growth of obesity is a problem that affects the whole of Europe. In order to raise awareness, it is best to have as much information as possible about everything that this disease implies for the body. Therefore, today we want to delve into the latest data that reveal the relationship between obesity and the brain.


According to various scientific studies, there is a great parallel between obesity and the brain. In fact, the more obese, the lower the volume of gray matter and there is less activity in the prefrontal cortex of the brain, responsible for complex thinking, self-control and planning.

Now, new research has come to light from the University of Leiden and has been collected by the journal Radiology. In it, it is analyzed how obesity can affect the brain, and it has been concluded that there is a high risk of dementia and cognitive impairment in those who have extra kilos. The purpose of the study was to obtain information on gray matter and white matter.

The gray matter is the one that is full of neurons, while the white one has nerve projections (axons and glial cells). The researchers concluded that having higher levels of fat in the body is associated with smaller volumes of relevant brain structures, such as gray matter.

In addition, it should be noted that the results vary depending on whether it is men and women. Obese men have a less gray matter, which implies fewer neurons, and obese women have a lower rate of matter in the region of the globus pallidus, where the nuclei of the basal ganglia are found, the key to controlling voluntary subconscious movements.

Experts are currently investigating whether this relationship between obesity and the brain may be due to chronic inflammation in the body of those who have greater body fat, something that could also affect brain tissue.
