Why anxiety affects the weight of the body: answer of scientists

I’m sure many have noticed that when excessive anxiety a person begins to lose weight. Still no one could give this phenomenon a full explanation, but scientists from the research Institute of SCRIPPS found that the root cause is the lack of protein, BDNF, is responsible for the development of neurons in the brain. The discovery was made during observation of the rats, keep high-calorie diet, but feeling anxiety.

The author of the study can be considered as the employee of the Institute named Baoji Xu. He found that lab rats are not able to gain weight if you are in a state similar to human anxiety. Their condition was aggravated by the removal of a molecule of BDNF from the cortex to the hippocampal region and the amygdala — this operation reduced the activity of gamma-aminobutyric acid, which is responsible for a state of relaxation.

Further study showed that being in the stress rats were forced to spend a lot of energy to maintain the body in working condition. Their forces were actively spent on the production of brown fat, which is necessary to keep warm. Due to increased need for energy, their bodies accelerated metabolism, and therefore, they do not gain weight despite a diet high in fat.

It is noteworthy that in stress situations people are able to consciously replenish your energy by consuming excessively large amounts of food. As a result, many people do not lose weight, but rather gain it, which few people want.

Scientists hope that this knowledge will help them to develop new and more effective treatment of stress and obesity. They understand that to do this, they need many other studies that confirm the findings. In any case, the first important step has already been taken they found the item that connects two common problems.
