Does Brain Influence Our Appetite?

• May 6, 2024

Did you know that the brain is responsible for many people suffering from overweight or obesity? That's right, food intake and energy expenditure are controlled by complex neural systems, according to a study of the National Center for Biotechnology Information (NCBI).

The specialist in Appetite Neurobiology, Ranier Gutiérre z, ensures that the brain is made up of 85 billion glial cells and more than 86 billion neurons that are connected to each other, and from which arise all functions such as walking, eating and thinking.

Therefore, in an interview for GetQoralHealth , Dr. Ranier Gutiérrez, researcher of the Laboratory of Neurobiology of the Appetite of Cinvestav, explains that the relationship between the brain and appetite:

According to Veracruz University , the food intake is regulated by a complex system that involves the brain, the spinal cord and the hormones, as well as the organs of the body and the substances that they secrete.

Therefore, both the hypothalamus and the brain stem play a central role in the generation of appetite, just as the cortex and the limbic system are important during the process of craving, intake, the reward system and the pleasure of eating.

The key hormones that send information to the brain about the state of satiety of the body are ghrelin, peptides, insulin, leptin, oleoylethanolamide, which are found in the pancreas, in the intestinal tract and in adipose tissue.

Currently there are studies that seek to control this type of hormones to regulate appetite and maintain a stable weight or lose weight in a few hours, such as optogenetics; however, the tests have been carried out successfully in rodents, but their testing in humans is still lacking.
