Stress triggers the human processes that lead to rapid obesity

Sometimes eating enormous amounts of food literally saves people from stress. Very logical, that they quickly gain weight, but the amount of eaten food in this case plays the most important role. Researchers from the Institute for medical research Garvan found that under stress inside a person there are processes that lead to greater weight gain than eating the same amount of calories in his absence.

The discovery was made during monitoring of laboratory mice. The researchers found that prolonged stress mice consume more high-calorie fast food and accumulated fat. Another group of mice without stress during the experiment consumed the same amount of calories, but the weight gain proceeded much slower.

The blood test of mice showed that under stress the amount of insulin in their blood increases significantly. This is the beginning of a chain of processes, which ultimately leads to weight gain. Thus, insulin affects the tonsils that are beginning to develop many of the neuropeptide NPY, which apparently affects the body’s reaction to foods consumed.

When we stopped the production of NPY in the amygdala, the weight gain slowed down. Weight gain on diet with high fat content was the same as in the absence of stress. This shows a clear link between stress, obesity and NPY neuropeptides.

According to Professor Herbert Herzog, they have identified a vicious circle in which stress-induced high insulin levels have led to accelerated recruitment of body fat. This discovery has proved that the consumption of high-calorie foods when stress inflicts on the body blow double strength, which leads to obesity.

It is noteworthy that obesity in turn can lead to the destruction of the brain. This was said recently, scientists from the Netherlands — about their research can be read in our material.
