Not all fat cells are equivalent. Humans and other animals contain both white fat cells and brown fat cells, named after their color. Because increases in brown fat cells may aid weight loss, researchers are interested in factors that control the ratio of white fat cells and brown fat cells, as detailed in a 2017 article in Obesity Reviews. What is the mechanism for how brown fat cells aid weight loss

Brown fat cells are present in our body which helps in regulating the body weight. The main role of brown fat is to produce heat when the temperature of body is going down or when we are feeling cold. They burn energy in order to produce heat and burning energy comes from white fat which can be translated into weight loss. This is how the brown fat helps in weight management.

The brown fat is activated by cold temperatures and it helps our body fast our metabolism by providing heat by burning energy.
