Scientists have discovered that staying in the cold could help us lose weight. Researchers at the University of California found that exposure to the cold increases levels of a protein that helps form brown fat -the type of fat that generates heat and keeps us warm. Brown fat burns energy, which helps us lose weight.White fat stores excess energy, which results in weight gain. The researchers said that because air conditioning and heating give us constant, comfortable temperatures, our body's need for brown fat has decreased.They found that: "Outdoor workers in northern Finland who are exposed to cold temperature have a significant amount of brown fat when compared to same-aged indoor workers."

科學(xué)家發(fā)現(xiàn)在寒冷環(huán)境中能夠幫助減肥。加利福尼亞大學(xué)的研究人員發(fā)現(xiàn)待在寒冷的環(huán)境中能夠增加脂肪的水平，脂肪能夠有助于褐色脂肪的形成，這種脂肪能夠產(chǎn)生熱量，并使人們保持溫度。這種褐色脂肪可以燃燒能量，這將有助于減肥。白色脂肪能夠儲(chǔ)藏多余的能量，這將讓體重上升。研究人員說(shuō)由于空調(diào)和取暖設(shè)備能夠給予人們?cè)丛床粩嗟氖孢m溫度，所以身體所需要的褐色脂肪就會(huì)減少。他們發(fā)現(xiàn)：“在芬蘭北部，由于室外工作的工人能夠經(jīng)常接觸到冷空氣，他們比同等年齡的室內(nèi)工作者的褐色脂肪要多。

The research was conducted on two different control groups of mice. One group was injected with the protein that helps create brown fat. This group subsequently gained 30 per cent less weight after both groups were fed high-fat diets. The researchers say this could be good news in the fight against obesity. People who are obese have lower levels of brown fat than thinner people. Head researcher Hei Sook Sul said: "This protein could become an important target for research into the treatment and prevention of obesity and obesity-related diseases." She added: "If you can somehow increase levels of this protein…you could possibly lose more weight even if eating the same amount of food."

這一研究是通過(guò)兩個(gè)不同的老鼠對(duì)照組進(jìn)行的。一個(gè)對(duì)照組會(huì)注射脂肪，這將幫助老鼠產(chǎn)生褐色脂肪。隨之，人們給兩組老鼠使用了大量的高脂肪食物，第一對(duì)照組的體重減輕了30%。研究人員說(shuō)這對(duì)于對(duì)抗肥胖癥來(lái)說(shuō)是一個(gè)好消息。比起體型纖細(xì)的人群來(lái)說(shuō)，肥胖者的身體中的褐色脂肪明顯減少。研究組長(zhǎng)Hei Sook Sul說(shuō)：“這一蛋白質(zhì)將成為研究的目標(biāo)，并納入到治療和預(yù)防肥胖癥，以及其他與肥胖有關(guān)的疾病中來(lái)。”她補(bǔ)充到：“如果你能通過(guò)某種方式增加這一脂肪，即使你吃同等量的食物，你也可能會(huì)減少體重。
