London: Bugs in our large intestine may be slowing down the activity of brown or `good fat` that quickly burns calories and keeps us slim.Sandrine P. Claus and Jeremy K. Nicholson from Imperial College London decided to see how trillions of such bacteria, which inhabit the large intestine and aid in digestion, might affect brown fat.Brown fat burns calories quickly before they can be stored and exists in small deposits in the neck area and elsewhere - not like "white fat" in flab around the waist and buttocks, the Journal of Proteome Research reports.In experiments that compared "germ-free" (GF) mice, which don`t have large-intestine bacteria, and regular mice, the scientists uncovered evidence suggesting that the bacteria do influence the activity of brown fat, according to an Imperial College statement.
