A new study by scientists at the University of Sydney in Australia found that freezing is similar to exercise. Shake 10 to 15 minutes at a low temperature below 15 degrees Celsius, which is equivalent to the weight loss effect of moderate intensity exercise such as cycling 1 hour. The triggered hormone secretion helps the human body to produce brown fat (or red fat), which can be burned into heat.
A more convenient way to make brown fat active is to lower the indoor temperature. For people living in cold areas, as long as they are outdoors. However, researchers warn that it is hard to say, because the cold environment may stimulate people's appetite and make them eat more.
Extended data
Brown fat helps to lose weight.
Seppers from Boston, USA and his colleagues observed 1800 subjects with high-tech scanning technology. The results show that almost all adults have accumulated a small amount of brown fat in the collarbone and neck. Women have about 14 grams of brown fat, and men's brown fat is only half that of women. Another study was completed by a research team from Maastricht University in the Netherlands and research centers in Northern Europe, Finland and Sweden.
The subjects stayed in a low-temperature room with room temperature of about 16 degrees Celsius for two hours. The researchers observed the position and metabolism of brown fat in their bodies by positron emission tomography and nuclear magnetic resonance. The scanning showed that among the 24 subjects, 23 had an accelerated frequency of brown fat activity.
Nordic researchers found that low temperature increased the metabolic rate of brown fat in the body by 15 times. Finally, the two groups of researchers concluded that the older they get, the fatter they get, and the less brown fat they have. Brown fat becomes more active when the temperature drops slightly.
