Introduction: Almost 15% of world populations suffer from obesity. Obesity and insulin resistance are the key pathogenesis risk factors of type 2 diabetes mellitus (T2DM) and cardiovascular disease. Exercise training can accelerate metabolism and help to prevent the obesity and diabetes through induction of Irisin and triggers conversion of white adipose tissue to brown adipose tissue.

Methods and Materials: This review article has been performed by searching the Irisin, FN DC5, obesity and insulin resistance keywords in various databases such as SID, Google scholar, Magiran and Pubmed websites.

Results: The exercise increases the production of PGC-1α in the muscle. Previous studies demonstrated that PGC-1α up-regulates the production of FNDC5, which cleave and secrete an Irisin into blood circulation. Irisin (exercise hormone) is responsible for uncoupling protein 1 (UCP1) induction, which plays an important role through increasing heat generation and mitochondrial membrane induction of UCP1, increase heat generation via metabolism.

Discussion and Conclusion: Elevated Irisin production alleviate the obesity, glucose tolerance, and decreases insulin resistance. Although exercise increase Irisin and it increases brown adipocyte, it is unclear that why weight reduction cannot be seen with exercise. Bostrom et al., as research pioneers about Irisin, confirm a positive effect of Irisin on obesity and insulin resistance by inducing the group of mice to obesity, diabetes, and injecting FNDC5 to them.
