'Good' Fat is a New Weapon in the Obesity Fight
A new understanding of brown fat cells -- the "good" kind of fat that
burns energy and keeps you warm -- could lead to new treatments for
obesity.
Researchers managed to use a single molecular switch to turn immature
muscle cells into brown fat cells in the lab, suggesting that brown
fat may be more akin to muscle cells than conventional white fat
cells. Another team has discovered that a protein im****tant for bone
growth helped promote the development of brown fat tissue in mice.
Both teams said their new findings lend understanding about the
origins of brown fat, which releases energy, in contrast to
conventional white fat, which stores energy.
Researchers believe that if they can coax the body into making more
calorie-burning brown fat, this might help people obese people lose
weight.
