| Scientists uncover the mystery of sea otters' cold tolerance or bring enlightenment to human fat burning |
Sea otters have only a very thin layer of subcutaneous fat, but they can stay in the cold sea for a long time like polar bears, whales, walruses and other "fat people" with thick subcutaneous fat
.
A new study in the United States has found that the unique energy conversion function of sea otter muscle tissue plays an important role in protecting against cold, and this mechanism of protecting against cold may be inspiring for humans to burn excess body fat
According to a report from Agence France-Presse on the 8th, a research team from Texas Agricultural and Mechanical University found that the muscle tissue of sea otters directly converts most of the energy produced by metabolism into heat energy instead of completing muscle contractions and other actions
.
What surprised the researchers was that whether they were juveniles or adults, whether they were in the wild or in captivity, sea otters had a high self-heating ability, which was basically independent of the degree of exercise
The lead author of the research paper, Traver Wright, said that although the dense waterproof fur of sea otters can prevent the body from losing heat, it is not enough to help sea otters that inhabit the cold waters of the North Pacific to keep out the cold
.
However, sea otters are good at using energy "inefficiently" to generate heat
Wright said that understanding the metabolic mechanism of sea otters may help humans solve the problem of obesity
.
"If you know how to speed up your metabolism and energy consumption, you can theoretically promote human metabolism and burn off excess fat
The research paper was published in the American "Science" magazine on the 8th
