Stress fetches Fats!

Research says that social stress could fetch to heart disease by causing the body to deposit more fat in the abdominal cavity & could also speed up harmful plaque build-up in blood vessels.
The researchers found that the stress of social subordination results in the release of stress hormones that promote the deposition of fat in the viscera.

Visceral fat, in turn, promotes coronary artery atherosclerosis, the build up of plaque in the blood vessels that leads to heart disease, the leading cause of death in the world today. "Much of the excess fat in many people who are overweight is located in the abdomen, & that fat behaves differently than fat in other locations," said Carol A. Shively, principal study investigator, Wake Forest University School of Medicine (WFUSM).

"If there's too much, it can 've far more harmful effects on health than fat located in other areas," said Shively. He & his colleagues found that women & female monkeys 've a natural protection against heart disease, women typically develop heart disease, on average, 10 years later than men do. That protection seems to be lost when stress & visceral fat increase.

Researchers found that the monkeys with high social stress & larger amounts of visceral fat also had ovaries that produced fewer protective hormones. The study appeared in the current issue of Obesity.
