Eating junk food is more likely to get fat when you're stressed

Original title: Eating junk food is more likely to get fat when you're stressed
especially want to eat junk food indulgently when you're stressed? This could be a "double disaster". A new animal experiment has found that mice who are under more stress gain weight faster than carefree mice, as well as eating high-calorie foods.
researchers at the Australian Gavin Institute of Medicine reported in the new issue of the American Journal of Cell Metabolism that they analyzed different areas of the mouse brain and found that the phenomenon was caused by a molecular channel mechanism controlled by insulin in the brain.
the brain that controls eating is mainly the lower pasum, while the brain region that processes emotional reactions such as anxiety is the amygdala. The researchers found that the amygdala produces a molecule called neuropeptide-Y, a molecule that the brain naturally produces when dealing with stress, which stimulates eating and leads to weight gain. When this molecule in the amygdala brain region was shut down, the rate of weight gain was the same when the mice ate the same amount of food, regardless of psychological stress.
further analysis of nerve cells that produce neuropeptide-Y molecules has revealed that insulin is also found in these cells. Normally, the body secretes insulin after a meal, helping cells absorb glucose from the blood and send a "full" signal to the lower pasum. The study found that long-term stress in itself only slightly increased insulin levels in mice, but once combined with high-calorie foods, the mice's blood insulin levels were 10 times higher than in mice on a normal diet.
study also showed that long-term high insulin levels in the amygdala make nerve cells less sensitive to insulin, which in turn promotes levels of neuropeptide-Y molecules, increasing appetite and reducing the body's ability to consume energy normally. (Reporter Zhou Zhou)
