Exercise releases this fat-burning hormone - Burn Energy October 04, 2016 17:16

Exercise releases irisin, a hormone that helps the body shed fat and keeps it from forming, new research shows.

Researchers have learned more about how the hormone irisin helps convert calorie-storing white fat cells into brown fat cells that burn energy. Irisin, which surges when the heart and other muscles are exerted, also inhibits the formation of fatty tissue.

The findings, published in American Journal of Physiology—Endocrinology and Metabolism, suggest that irisin may be an attractive target for fighting obesity and diabetes, says Li-Jun Yang, professor of hematopathology at the University of Florida College of Medicine’s department of pathology, immunology, and laboratory medicine. The study is believed to be the first of its kind to examine the mechanisms of irisin’s effect on human fat tissue and fat cells.

Irisin appears to work by boosting the activity of genes and a protein that are crucial to turning white fat cells into brown cells. It also significantly increases the amount of energy used by those cells, indicating it has a role in burning fat.
