Brown fat and obesity

It is well known that obesity is due to the result of too much body fat, body fat sub-fat white and two brown fat. The latest study found that obese people tend to have more of the brown adipose tissue. Brown adipose tissue is considered to be a special Secretary of heat, brown adipose tissue to reduce or function, the function of the body heat production will be reduced, it will also reduce energy consumption. German scholars have found that brown adipose tissue thermogenesis through the realization of the receptor.

From the physical point of view, the human body's energy intake and consumption, to maintain a certain balance, both to increase intake of energy or reduce consumption will lead to abnormal energy metabolism, resulting in obesity. Furthermore, energy consumption is divided into at the time of resting energy expenditure and energy expenditure of exercise, resting energy expenditure at the time of thermal energy accounted for 50% to 70%. Movement of the increase in energy consumption of course, play an important role in obesity, but when the rest of the reduction of energy consumption are obese have played an important role to another.

Obese basal metabolic rate is often lower than normal. Basal metabolic rate, as reflected in the human body is resting in a state of energy consumption, specifically refer to the body's energy metabolism in the rate of clear-headed and very quiet state, free from muscle activity, ambient temperature, food and affect factors such as stress .

With further research, in recent years of resting energy expenditure Research has made some progress. Obesity on the survey found that some obese people do not eat more than normal and sometimes even eat less than normal, although some also took part in the campaign, but still no drop in body weight. Therefore of the view that these obese there is a low energy consumption, nutritional intake is to say that they rarely consumed in the form of thermal energy, but the more nutrients into energy stored up. Researchers in the body of a newly discovered brown adipose tissue, obesity can be explained this anomaly.
