A diet and physical inactivity, we should add
another risk factor for obesity: stress. If we suspected, the scientific
evidence is now available, demonstrating that weight gain can be directly due
to stress. Even better, a molecule involved was identified, opening up broad
prospects
Stress is source of
abdominal obesity
At equivalent power, some people
gain weight as a result of stress. Excess fat seems favored by stress is particularly
accumulates in the abdomen. Now we know that abdominal obesity more exposed to
the risk of cardiovascular disease and diabetes. In experimentally subjecting
mice to stressful situations (aggressiveness congeners, exposure to cold ??),
we see that they grow twice as as non-stressed mice, equivalent diet rich in
fat and sugar. Indeed, if the plan is not high calorie but normal, stress has
no effect on weight.
Neuropeptide Y governs fatty
proliferation
Moreover, given that in cases of
stress, cerebral production of a molecule called neuropeptide Y increases,
researchers have tried to block this process. They used the same protocol as
above, but in addition injected into the abdomen of mice under stress a
substance capable of blocking the action of neuropeptide Y. Under these
conditions, they will not grow more than the non-stressed mice. Conversely, the
intra-abdominal injection of neuropeptide Y in two weeks causes a 50% increase
of the abdominal tissue. Y peptide, the concentration is increased by stress,
therefore promotes the proliferation of fat cells.
New treatment perspectives
This discovery opens a new path to
the pharmaceutical industry for the development of new drugs to treat or
prevent obesity. But this track could also be applied to greasy remodeling in
the context of plastic, reconstructive and aesthetic. Indeed, it is conceivable
to increase the volume of the cheeks, buttocks, lips ?? Meanwhile, people who
wish to lose weight should also look at their stress levels. Logically, learn
to fight and manage stress can help to lose weight or fat ??
