A form of brown fat that's switched on when people are cold sucks fat out of the rest of the body to fuel itself, while another type of brown fat can be created from white fat by exercise, according to two new studies.
The findings suggest that being able to achieve this without making people cold or forcing them to exercise all the time could offer a highly-effective way to lose weight, The New York Times reported.
In one study, researchers found that the metabolic rate of men who were kept chilled increased by 80 percent due to effects of brown fat. On average, the brown fat burned about 250 calories over three hours.
The study was published in the Journal of Clinical Investigation.
In the other study, researchers conducted experiments with mice and found that exercise causes white fat to turn into brown fat. Exercise causes muscles to release a hormone that converts white fat cells into brown fat cells, which burn extra calories, The Times reported.
The researchers suspect this also occurs in humans.
