Monkeys fed with an American Get Diet - but those under chronic stress put in much more fat of the belly.
This extra belly fat is because forced monkeys are much more likely to undergo blocked arteries and metabolic syndrome, a constellation of risk factors for heart disease, suggest Carol A. Childively, PhD and colleagues Wake Forest University.
in previous studies, the team of earnestly showed that socially stressed monkeys - those at the bottom of the peching order in a monkey colony - get so much faster blocked arteries than other monkeys fed with The same high fat diet.
But why do stressed monkeys get more belly fat?
"We wanted to know more about how the stress out of you is turned into a plate inside your arteries," says WebMD. "Then we look at the course caused atherosclerosis in our monkeys."
More than a period of two years, compounds and colleagues have collected a wide range of data on stressed and ungrounded female cynomolgous monkeys. The studies included a computed tomography to detect visceral abdominal fat that often (but not always) projects like a "beer belly" from the outside. Inside, it involves the organs.

Even compared to other monkeys with the same body mass index and weight, TC tests have shown that forced monkeys had a large business of belly fat. And when the researchers looked at the arteries of the animals, they found the board clogging the arteries of the stressed monkeys.
", so it's not how much fat you have, but where it is located," he says lively. / p>
During the study years, low status monkeys had high levels of a stress hormone called cortisol. Over time, high cortisol levels cause belly fat to accumulate. It also makes individual fat cells are larger.
This is "sick fat," says Harold Bays, MD, medical director of the Metabolic Research Center and Atherosclerosis Louisville. The bays reviewed the study timidly for the WebMD.
"Your body fat can get sick like any other body fabric," says Bays. "Your fat cells are getting bigger and your fat tissue is getting bigger and neither cells nor the tissues work as well as they should. Fat is sick."
"The monkeys that have very abdominal fat has metabolic syndrome, as well as people with great abdominal fat," he says lively. "When you have a lot of fat in visceral fat cells and all the characteristics of metabolic syndrome, each of these things promotes atherosclerosis."
All monkeys in the inventory study were female. One way of monkeys are like human beings is that females are less likely to get heart disease than males. Still stressed female monkeys that put the belly fat are at least so prone to get heart disease as they are male monkeys.
"So this is a good model for women with heart disease. When women receive visceral fat and metabolic syndrome, which completely abolish women's protection," he says happily. "Any edge that they earn for being a female is totally disappeared. And, in fact, it may even be a worse illness for women than men, because they receive complications and die faster when they have heart disease."
Colleagues discovered that stressed monkeys had abnormal menstrual cycles. Compared to the aim monkeys, they were much less prone to ovulate. This was connected to abdominal fat - but not the body mass index or other types of fat."We do not know about ovarian function in women with metabolic syndrome, but probably this is something we should look at in," she says brightly. "Because the menstrual system protects against osteoporosis and loss of cognitive function. Depressed ovarian function in women is not a good thing".
Bays says he is not surprised by this finding.
"All these things are interconnected," he says. "The central theme is that only should not be a mystery because if you gain weight, you receive metabolic disease."
