It would Seem, if mice are anything to go on, Which you Are more likely to gain weight if you eat when you Are Worried . Scientists have discovered a high-calorie diet absorbed when under stress contributes to greater weight gain compared to when the same diet is consumed in a stress-free environment.
Professor Herbert Herzog, In the Garvan Institute of Medical Research in Sydney, Australia, who led the trial, says:”This study indicates that we must be more aware about what we’re eating when we’re stressed, to avoid a quicker development of obesity.
“This really reinforced the thought that while it’s bad to consume crap food, eating high-calorie foods under pressure is really a double whammy that compels obesity”
Professor Herzog, who described the findings as a”vicious cycle”, stated when stressed most people will achieve for high-calorie foods rich in fat and sugar.
The researchers had looked at different Regions of the brain in mice While consuming them a high calorie diet under different states, firstly stress-free, minute stressful.
Stressed mice became heavy”more rapidly” than those who consumed the exact same high fat food at a stress-free atmosphere.
Tests Showed a molecule called NPY played a vital part in the weight reduction, as it reduced their ability to burn off calories. The human brain generates NPY naturally in response to stress, stimulating the need to eat in us as well as mice.
Study co-author Dr Kenny Chi Kin Ip said:”We Discovered when we turned off the production of NPY in the amygdala [it handles our emotions and anxiety], weight gain was reduced.
“Without NPY, the weight gain on a high fat diet with anxiety was the Same in the stress-free environment as weight gain. This shows a clear connection between stress, obesity and NPY.”
The Team also analysed the neural cells which produce NPY from the amygdala to determine why there’s a surge during anxiety and found they had receptors for insulin, the hormone that controls blood sugar levels.
Under Standard conditions, the body produces insulin after a meal, which helps cells absorb sugar in the blood. It also sends a”stop eating” signal to the hypothalamus, the part of the brain that controls appetite.
But in conjunction with a high-calorie diet, the insulin levels were 10 times higher in stressed mice.
The Prolonged, elevated levels of insulin caused the nerve cells to become Desensitised and without the capacity to detect insulin, more NPY was created.
