Exercise Releases Fat-Shedding Hormone

Exercise not only will burn off excess calorie storage, but may also help release chemicals within the body that keeps fat from forming!

Many, many research studies show the benefits of regular physical activity – not the least of which is helping one reach a healthy weight. Researchers from the University of Florida also find that the release of irisin during exercise can help convert calorie-storing white fat cells into energy-burning brown fat cells.

Li-Jun Yang MD, a professor of hematopathology, and his team published the recent findings in the American Journal of Physiology – Endocrinology and Metabolism. They found that irisin, which surges when the heart and other muscles are under exertion,, works by boosting the activity of genes and a protein crucial to fat-burning.

In addition, the team found that irisin suppresses fat-cell formation by as much as 20 to 60%. It does so by hindering a process within the stem cells that would turn them into fat cells. Instead, they become bone-forming cells.

While it's possible that the beneficial effects of irisin could be developed into a prescription medication to fight obesity, Yang said that is uncertain and remains a long time away.

"Instead of waiting for a miracle drug, you can help yourself by changing your lifestyle. Exercise produces more irisin, which has many beneficial effects including fat reduction, stronger bones and better cardiovascular health," Yang said.
