棕色脂肪的人可以多消耗15%的卡路里

Short-term cold exposure may help people with brown fat burn 15 percent more calories than those without, according to a small study published in the Endocrine Society’s Journal of Clinical Endocrinology & Metabolism.

一项发表在《临床内分泌与代谢》杂志上的小型研究显示，短期寒冷暴露可能有助于棕色脂肪的人比没有棕色脂肪的人多燃烧15%的热量。

Unlike white fat, brown fat burns calories through fatty acid oxidation and heat production and is considered a promising target in the fight against the obesity epidemic. The biggest activator of brown fat is moderate cold exposure.

与白色脂肪不同，棕色脂肪通过脂肪酸氧化和热量产生燃烧卡路里，被认为是对抗肥胖流行病的一个信息网。棕色脂肪的最大激活剂是适度的冷暴露。

“This data improves our understanding of how brown fat works in humans,” said the study’s corresponding author, Florian W. Kiefer, M.D., Ph.D., of the Medical University of Vienna in Austria. “We found that individuals with active brown fat burned 20 more kilocalories than those without.”

“这些数据提高了我们对棕色脂肪在人体中作用的理解，”该研究的相应作者、奥地利维也纳医科大学的弗洛里安·W·基弗医学博士说。“我们发现，棕色脂肪活跃的人比没有棕色脂肪的人多燃烧20千卡的热量。”

The researchers identified two groups using a PET scan—those with and without active brown fat. They analyzed brown fat function and energy expenditure in these individuals before and after short-term cold exposure finding that the group with active brown fat not only burned significantly more calories but had a healthier fatty acid blood profile.

研究人员通过PET扫描确定了两组具有或不具有活性棕色脂肪的人。他们分析了这些人在短期寒冷暴露前后的棕色脂肪功能和能量消耗，发现棕色脂肪活跃的那一组不仅燃烧了更多的热量，而且血液中的脂肪酸也更健康。

“We have to study human brown fat in more detail to see if this organ can protect us against metabolic and cardiovascular disease,” Kiefer said.

基弗说：“我们必须更详细地研究人类棕色脂肪，看看这个器官是否能保护我们免受代谢和心血管疾病的侵害。”。
