問題詳情:
Scientists have discovered that ____61____(stay) in the cold could help us lose weight. Researchers at the University of California found that exposure(暴露) to the cold increases levels of a protein(蛋白) that helps form brown fat ----the type of fat that produces heat and keeps us warm. Brown fat burns energy, _____62______ helps us lose weight. White fat stores extra energy, which results _____63_____ weight gain. The researchers said that because air conditioning and heating give us constant, _____64_______(comfort) temperatures, our body's need for brown fat has decreased(減少). They found that: "Outdoor workers in northern Finland who ______65______(expose) to cold temperature have ____66_____ big amount of brown fat when ____67_____(compare) to same-aged indoor workers."
The research was conducted on two different control groups of mice. ____68_____ group was injected(注入、注*) with the protein that helps create brown fat. This group later gained 30% less weight after both groups were fed high-fat diets. The researchers say this could be good news in the fight against obesity(肥胖). People who are obese have __69__(low) 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 ____70_____(possible) lose more weight even if eating the same amount of food.
