What is the difference between white fat in the body from brown and beige, says an endocrinologist with 23 years of experience
Adipose tissue is a powerful topic that you can go headlong into.
It has long ceased to be perceived as a simple storage of energy, and quite deservedly recognized as an organ capable of synthesizing many biologically active hormone-like substances and hormones. Moreover, its began to separate by color - on white, brown and beige. The latter was completely unexpected, but no less interesting.
What's the difference?
White fat
In a nutshell, it is a complete energy store and a factory for the production of substances that cause inflammation.
When there is too much white adipose tissue, this is the beginning of global and bad events, for example, metabolic syndrome.
Brown fat
On the contrary, he has absorbed all the best that is possible. For example, he
protects us from the cold. There is a lot of it in babies: in this way, nature protects babies from the negative effects of cold. With age, the percentage of brown adipose tissue decreases, there was even an assumption that it disappears completely. But recent studies have shown that in adults, it persists, for example, in the supraclavicular region, along the spine, adrenal glands, and here and there else.There are also observations that it is higher in people who constantly work in cold conditions, for example, among builders in the north or among reindeer herders. Athletes also have more brown fat, and most likely swimmers are in the lead here, because their thermoregulation is undergoing great tests.
In brown fat, there are a lot of mitochondria - the energy and heat furnaces of the body. Therefore, free fatty acids are constantly burned there. And with an intensity five times more than usual. I.e the greater the percentage of brown fat we have, the easier it is for us to lose weight.
And the most important difference from white adipose tissue is that anti-inflammatory substances are synthesized in brown, which are absolute antipodes of what happens in white fat. Of course, inflammatory ones too (fat is fat), but there are much more anti-inflammatory ones.
Beige fat
Not everything is clear with beige adipose tissue. It is clear that humans have more of it than animals. There was an interesting study where patients with hormone-active adrenal tumors synthesizing in a large amount of norepinephrine and adrenaline, beige fat was significantly more than others people. In other words, activation of the sympathetic nervous system stimulates the growth of beige fat.
What's the conclusion?
Drive off white fat and try to save brown. This means more cold, fresh air, physical activity, hardening. And scientists will follow the beige.
