Scientists have discovered that    1    (stay) in the cold could help us lose weight.

Brown fat burns energy,     2    helps us lose weight. White fat stores extra energy, which results     3    weight gain. The researchers said that because air conditioning and heating give us constant,     4    (comfort) temperatures, our body’s need for brown fat has decreased. They found that: “Outdoor workers in northern Finland who    5    (expose) to cold temperature have    6    significant amount of brown fat when    7    (compare) to same-aged indoor workers.” The research was conducted on two different control groups of mice.     8    group was injected 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. People who are obese have    9    (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    10    (possible) lose more weight even if eating the same amount of food.”
