How to convert white fat into brown, and why it is important for those who want to lose weight

Thanks to the latest study, the researchers found that exercise not only burn extra inches in problem areas. They are pushing the metabolism and turn the standard (white), brown fat, which burns more calories.
What is brown fat
Brown fat (Brown Adipose Tissue) provides or thermogenesis of heat production due to combustion of fat. People with obesity, as a rule, contain a much smaller amount of brown fat in comparison to white.
His cells have the exclusive feature - they contain a lot of mitochondria (organelles responsible for the accumulation of energy in the cell). In the mitochondria of brown fat cells have special protein UCP1, which instantly converts fatty acids into heat, bypassing phase ATP synthesis.
brown fat It allows you to burn fat. When you activate it happens transfer of fatty acids from white adipose tissue to brown. White fat is stored under the skin, in the glands and internal organs capsules. Brown fat instead of energy storage burning it in large quantities, releasing heat.
In a recent studyIrisin exerts dual effects on browning and adipogenesis of human white adipocytes. it was found that during exercise the type of fat cells is transformed from a metabolically inactive (white, standard fat) in brown fat, which burns more calories.
Now scientists have even more evidence that the number of calories burned during exercise is not limited.
This fact is the key to all the other benefits that we get from exercise. This is how the author believes that Lee Joon-Young study (Li-Jun Yang), Hematopathology professor at the University of Florida.
Everyone knows about the benefits of exercise, but few people think about the mechanisms that trigger these processes. Of the study explains why people regularly involved in sports a slender body and more dense bone structure. In addition, exercise help prevent obesity, metabolic diseases (such as diabetes type II), heart problems and stroke.
How it works
During physical activity, the body produces a number of hormones. One of them - irisin hormone - is responsible for the regulation of the process of fat digestion (lipolysis) in the body. It is considered a potential fat burner.
In the laboratory, the fat cells are exposed to irisina. Under its influence has increased the activity of another protein that turns white fat into brown.
Brown fat helps the body to burn as many calories and not as their stores the inventory in secluded places on the waist or hip area.
In addition, brown fat has a positive effect on other aspects of the metabolic process: insulin sensitivity and glucose tolerance. These processes help to prevent obesity, type II diabetes and cardiovascular disease.
For the first time in the transformation of an ordinary brown fat after exercise was observed in mice. During a recent study, this same effect has been observed in humans.
At this benefit from the development of an organism irisina not end there. Scientists have also found that when mixed with stem cells in adipose tissue (fat young cells that have not reached a mature state) irisin makes it not the standard fat tissue and into something otherwise. Under the influence of the hormone stem cells become completely different kind of fabric, which seals the structure bones and makes them stronger.
Another interesting fact. In fat tissue sample with the addition of a standard amount irisina white fat 20-60% less than in the sample without added hormone. It should be noted that the experiments were performed on human tissue samples, rather than the man himself. The next step - to repeat the experiment in humans to definitively confirm the impact irisina in real life, rather than in the laboratory.
Such exposure irisina on our body can be considered as an additional incentive for training, research and let the findings have not been confirmed by 100%. And while Dr. Young and his colleagues will work on evidence in the university, we can continue to work on his body at the sports club.
