Brown fat can help fight obesity, researchers claim

Brown fat can help protect the body from obesity and diabetes, researchers have argued.

Also known as brown fat tissue, brown fat is considered to be a heating organ.

People have a few grams of it in areas including the neck, leg bone, kidneys and spinal cord.

Researchers have found that when activated by cool temperatures, brown fat uses sugar and fat from the blood to generate heat in the body.

Published in the Nature journal, the study found brown fat can also help the body filter and remove branched amino acids (BCAA) from the blood.

These amino acids ̵

1; leucine, isoleucine and valine – are found in foods such as eggs, meat, fish, chicken and milk.

They can also be found in supplements used by some athletes and people who want to build muscle mass.

While normal concentrations of these amino acids are important for good health, they are in excessive amounts linked to diabetes and obesity. [19659002] Researchers found that people with little or no brown fat have reduced the ability to clear BCAA from the blood, which can potentially lead to the development of the conditions.

Co-author Labros Sidossis, chair of the Department of Kinesiology and Health at Rutgers University- New Brunswick said: “Our study explains the paradox that BCAA supplements can potentially benefit those with active brown fat, like healthy people, but can be harmful to others. , including the elderly, obese and people with diabetes.

The researchers say the study also solved a 20-plus year mystery about brown fat – how BCAA gets into the mitochondria that generate energy and heat in cells.

They found that a new protein controls how fast brown fat cleanses. the amino acids from blood and use them to produce energy and heat.

Next, they must determine whether uptake of brown fat BCAAs can be controlled by environmental factors – such as exposure to mildly cold temperatures or consumption of spicy foods – or by drugs.

This can improve blood sugar levels linked to diabetes and obesity, Professor Sidossis said.
