MindBodyGreen reports on a systematic review and meta-analysis of 50 randomized controlled trials, covering 1,780 adults with overweight or obesity, that found exercise raised blood levels of irisin, a hormone released by muscle during activity. Exercisers also had lower fasting glucose, insulin and LDL cholesterol. Resistance training produced the largest irisin rise, though differences between exercise types were not statistically significant.
