There is a new way to lose weight are more secure than the use of diet drugs, namely by activating fat ‘good’ in the body. These good fats can work best at cooler temperatures.According to a new study published in the journal PNAS USA, the temperature of the cold air can turn good fats in your body that burns calories and ultimately lose weight.
Good fats are the brown adipose tissue, also known as brown fat is found naturally in humans. Previous experiments have shown that brown fat may be induced in mice, which promises a weight loss therapy in the future, but scientists have not demonstrated efficacy to stimulate brown fat in humans.Researchers from the Joslin Diabetes Center in Boston wanted to compare the effects of ephedrine, a stimulant in the drugs used in weight loss, with cold temperatures.
Scientists had previously predicted that the cold temperature can activate brown fat.The team conducted tests on the 10 study participants with three different ways. Participants were given an injection of ephedrine and there is a cooling vest.
Then after two hours, the researchers measured the activity of brown fat with PET or CT scan.The researchers found that ephedrine does not stimulate the activity of brown fat. Participants who wore a cooling vest for two hours showed a significant brown fat activity in the scan test.”We have found a way to stimulate brown fat in an effective and apparently safe to use a mild sensation of cold activation. We also compare it with the weight loss drug that does not have the same effect terhadadap activity of brown fat,” said Dr. Aaron Cypess, the author the study and a physician at the Joslin Diabetes Center as reported by ABCNews,.
However, ephedrine can increase the body’s sympathetic nervous system activity. These activities include increased blood pressure and heart rate and slows digestion.Ephedrine inability to inhibit the activity of brown fat may be the reason why so many diet pills do not indicate a favorable long-term results.
“The problem with the use of ephedrine is whether the use of these drugs will continue to activate the sympathetic nervous person. It is much better if weight loss is done only by activating brown fat without having to activate the sympathetic nervous” said Cypess. There is still much more research needs to be done to find out what the best way to stimulate brown fat through the cooling temperature. Because maybe someone will feel uncomfortable if you have to wear a cooling vest if you want to lose weight
