Till date, scientists had polar opinions on the mysterious hormone “irisin” that is believed to be produced after exercise. Some researchers believed that irisin was the reason that made people healthy and helped them in reducing weight while some questioned the existence of the irisin hormone. However, a new research has collected enough proofs to confirm the existence of exercise hormone irisin.

According to researchers from the Harvard Medical School, they had discovered the irisin back in 2012, and they conducted several experiments on the mice to confirms it effect on health. Researchers found that irisin improved blood sugar regulation and led to reduction in weight cutting down obesity risk.

To identify the hormone, researchers used a technique named quantitative mass spectrometry in which protein is broken down into smaller particles so that specific proteins can be identified on the basis of mass of molecules. Irisin was identified in blood samples of people who did exercise and those who didn’t. People who did exercise for 12 months had 4.3 nanograms per milliliter of the exercise hormone while it was 3.6 nanograms per milliliter in those who sat idle.

Lead researcher Bruce M. Spiegelman, a professor of cell biology and medicine at Harvard Medical School said that the study confirms the fact that exercise increases irisin levels in the body that ultimately makes on fit. Although irisin is present in small amount in the blood like insulin and leptin but its presence is equally important

The study states increase in concentration of exercise hormone with the exercise but it does not link irisin with health benefits. More research is needed to prove that it is beneficial for health. “There’s so much that we don’t know about the molecular mechanisms of exercise,” Alisa Blazek, a graduate student at The Ohio State University’s Department of Molecular, Cellular and Developmental Biology said. “And if we could learn more about them, it can help us to design therapeutics, and learn how effective our exercise or physical therapy programs are.”

    it is time people stop looking into genes and hereditary causes of obesity and rather just discipline yourself to follow a diet. New diet is not needed to lose weight, but you just need to stay disciplined to lose weight.

    There are plenty of already working diets which you can use instead of looking for newer and newer research. I used the diet of lisa plog and lost 22 pounds. So there are existing diets which work and there is no need to look for newer and newer type of diet plans. Google for “lisa plog diet plans” to find the diet which I used.

    People are just getting confused by these newer and newer type of diet plans.
