Irisin best known as the hormone of physical activity,
fat-burning hormone or hormone in obesity, is a powerful ally to combat obesity
and diabetes. Its action in the body is related to the presence of white
adipose tissue (white fat) and brown or brown adipose tissue (brown fat).
The white adipose tissue cells specialize in storing
nutrients as fat, and represent the main form of reserve energy in humans. The
brown fat, however, is only evident in newborns and is located in strategic
areas to give warmth to the vital organs. The main function of this type of fat
is to use ingest nutrients and burned to release heat, instead of being stored
as fat.
In adults, the heat production of brown fat is replaced by
generating the activity of the muscles themselves. This happens in people of
normal weight as those who are obese, because the latter is increasing white
fat and not brown.
How it works.
Doctors try to determine how you can increase this amount
can not be combined and brown fat, while decreasing the white (fat).
They found that exercise produces physical a variety of
benefits, and some of the most recognized effects are mediated by a factor called
PGC1-a, that triggers muscle cell irisin hormone is released.
The irisin produces white grease which becomes brown,
increases the expense of calories and increases the production of heat. This
causes your body to be less energy-saving white as fat.
As brown fat helps burn calories, the interesting thing is
that it could actually increase in the adult and thus help you lose weight or
not to continue increasing.
Without physical activity no result:
Increased irisin linked to physical activity. His role
against obesity is that when applied to a body, it burns more calories.
It was found that the generation of the person irisin
improves control your blood sugar level, so it could also be effective in
treating diabetes.
