Good Fat Bad Fat, Brown Fat White Fat: New Hope for Fat People

Once upon a time, fat was bad, thin was good, but now it’s not so simple. It turns out that some fat is bad, and some fat is good. The Scientific American reports that two studies, published in Nature, describe two different proteins that control
the creation of a good type of fat, known to scientists as brown fat. What’s so good about brown fat? According to Sciam, it releases energy and encourages calorie burning, unlike white fat–the bad kind, which stores calories.
Where has this good "brown fat" been all of our lives? It disappears, unfortunately, shortly after birth—when it has fulfilled its role of keeping
a newborn’s body temperature stable. In mice, however, it persists
until adulthood, primarily between the shoulder blades, where it
performs the same internal climate-control function. Sciam reports that scientists imagine that it may be possible to inject the good, brown fat cells into areas of bad, white fat, and essentially jump start a fat burning process.
