London: Want to shed your baby fat? Wait, don`t do it just yet, for a new study has revealed that such a fat is good - as long as it is calorie-burning ``brown fat``.
By evaluating biopsy tissue of what appeared to be brown fat, the authors confirmed that they were, indeed, looking at stores of brown fat. The researchers found that brown fat was located in an area extending from the front of the neck to the chest. Of the subjects who had detectable brown fat, about 6 percent had 3 ounces or more of the fat. "We believe that this percentage greatly underestimates the number of adults in the population who have a large amount of brown fat," said Cypess. They also discovered that brown fat is most abundant in young women and least frequent in older, overweight men. In fact, women were more than twice as likely as men to have substantial amounts of brown fat. "One theory for this is that women may have less muscle mass overall, so they need more brown fat to generate heat and keep warm," Cypess said. The study appears in New England Journal of Medicine.
