Researchers at Yale University have published a study in the journal Nature Metabolism. Explain that the brains of people with obesity have a low response to nutrients in food and release less dopamine.. Even after weight loss, the brain did not return to proper functioning.
The consequences of being overweight have been widely studied in various fields of study.
Some facts are already well understood, such as the impact of overweight on the development of cardiovascular, musculoskeletal and metabolic diseases.
However, there is still a lot of research being conducted on the effects of being overweight on the functioning of the brain and brain systems.
It is known that there is an axis of communication between the gut and the brain. According to research, this axis is linked to various processes in our body.
For example, when we eat certain foods, the brain recognizes nutrients and releases hormones that give us a sense of well-being, fullness, thirst, among other information. Despite According to a study by scientists at Yale University, this system can be damaged in obese people..
In a randomized study, researchers looked at the brain responses of two groups of people to imaging tests. The first included people with obesity, and the other included people whose BMI (body mass index) was in the range considered normal.
During testing, the brains of people with obesity were less responsive to the presence of food offered to the group. less dopamine release as a result.
But the research went even further. To see if the recognition and reward system could return to “normal”, the researchers reassessed the participants after they lost 10% of their initial weight.
Even after losing weight There was no restoration of the nutrient recognition system and dopamine release.at least in the short term.
The need for more food to feel the same vitality and fullness may be an explanation for weight gain, even after successful weight loss.
The researchers explain that more research is needed to understand these relationships and whether this process is truly irreversible.
