Sometimes eating huge amounts of foodliterally saves people from stress. It is quite logical that at the same time they quickly gain weight, but in this case the volume of food eaten plays far from the most important role. Researchers at the Garvan Institute of Medical Research have found that stress leads to processes that lead to greater weight gain than eating the same amount of calories in the absence of it.
The discovery was made during the observation oflaboratory mice. Researchers noticed that during prolonged stress, mice consume much more high-calorie foods and quickly accumulate fat. Another group of stress-free mice consumed the same amount of calories during the experiment, but weight gain was much slower.
A blood test of mice showed that under stressthe amount of insulin in their blood increases significantly. This becomes the beginning of a whole chain of processes that ultimately leads to weight gain. Thus, insulin affects the work of the tonsils, which begin to produce a lot of neuropeptide NPY, which apparently affects the body's response to the food consumed.
When we stopped the production of NPY inalmond, weight gain slowed. Weight gain on a high-fat diet was the same as without stress. This shows a clear link between stress, obesity and the neuropeptide NPY.

According to Professor Herbert Herzog, they succeededidentify a vicious cycle in which high levels of insulin caused by stress led to an accelerated collection of body fat. This discovery proved that eating high-calorie foods under stress causes a double-blow to the body, which leads to obesity.
It is noteworthy that obesity in turn can lead to the destruction of the brain. This was recently stated by scientists from the Netherlands - their research can be read in our material.
