Role of Irisin in exercise

Exercise stimulates the release of MYOKINES which offer protection against many diseases including diabetes, cancer and dementia, but until recently they weren't sure why. Now there's a newly discovered myokine named for the Greek goddess Iris (messenger), IRISIN, which is the messenger from the muscle during exercise "talking" the white fat into brown fat which burns calories into heat. Or something like that. When I googled it I see there's already a pharmaceutical company producing it, but you can do that on your own by exercising. Read a dumbed down version here.
