Scientists explain why we are overeating



Researchers at the Max Planck Institute in Germany explained why people tend to overeat. The study in question was published in the journal Cell Metabolism.

According to the EurekAlert portal, this fact is associated with the release of dopamine in the brain, a hormone that produces a sense of pleasure. Experts suggest that the release of this hormone occurs twice during ingestion of a meal: when the food is swallowed and when the stomach is reached.

Two peaks of dopamine release

"With the help of the new technique of positron emission tomography we developed, not only did we manage to find the two peaks of dopamine release, but also to identify the specific brain regions that were related to these editions," he said. Lead author of the study, Mark Tittmeyer.

The survey included 12 volunteers, some of whom received a tasty drink, and others – a non-existent solution. When analyzing the data, the scientists found that the greater the desire for a tasty drink, the less amount of dopamine was released when the food was already in the stomach.

"On the one hand, the release of dopamine reflects our subjective desire to consume food, and on the other hand, our desire seems to suppress the release of dopamine caused by the intestines," another researcher, Hayko Bakes, said.

Therefore, the study concluded that the suppression of the release of dopamine caused by the gut can cause us to overcome the highly desired products. "We continue to eat until enough dopamine is released," concluded Bakes.
