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.

一項發(fā)表在《臨床內(nèi)分泌與代謝》雜志上的小型研究顯示，短期寒冷暴露可能有助于棕色脂肪的人比沒有棕色脂肪的人多燃燒15%的熱量。

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.

與白色脂肪不同，棕色脂肪通過脂肪酸氧化和熱量產(chǎn)生燃燒卡路里，被認(rèn)為是對抗肥胖流行病的一個信息網(wǎng)。棕色脂肪的最大激活劑是適度的冷暴露。

“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.”

“這些數(shù)據(jù)提高了我們對棕色脂肪在人體中作用的理解，”該研究的相應(yīng)作者、奧地利維也納醫(yī)科大學(xué)的弗洛里安·W·基弗醫(yī)學(xué)博士說。“我們發(fā)現(xiàn)，棕色脂肪活躍的人比沒有棕色脂肪的人多燃燒20千卡的熱量。”

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.

研究人員通過PET掃描確定了兩組具有或不具有活性棕色脂肪的人。他們分析了這些人在短期寒冷暴露前后的棕色脂肪功能和能量消耗，發(fā)現(xiàn)棕色脂肪活躍的那一組不僅燃燒了更多的熱量，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.

基弗說：“我們必須更詳細(xì)地研究人類棕色脂肪，看看這個器官是否能保護我們免受代謝和心血管疾病的侵害。”。
