There is hope for those of us battling weight gain and obesity. An article appeared this week in the journal Endocrinology discussing the research of Wanzhu Jin, PhD, of the Chinese Academy of Sciences involving weight loss and reversal of Type I diabetes. Researchers are well aware of the different types of lipid or fat in all mammals. Brown fat or brown adipose tissue has been felt to have protective effects against weight gain, lipid abnormalities and glucose metabolism problems.
Dr Jin, used mice that were genetically engineered to be overweight or fat. He injected them with a quantity of Brown Adipose Tissue (BAT) and these mice lost weight and improved their glucose metabolism into the non-diabetic range. The success in weight loss and sugar control was felt to be due to the BAT increasing the energy expenditure of the genetically altered mice. The sugar control occurred through similar mechanisms and was unrelated to the production of insulin or insulin metabolism. Dr Jin’s team of researchers felt that the transplanted brown adipose tissue activated and enhanced the BAT already present in these obese mice allowing it to produce the weight loss and improvement in glucose and lipid metabolism. Their research seemed to hint that brown adipose tissue actually acted as an endocrine gland like the pancreas or adrenal gland or thyroid gland, secreting substances that improved metabolism of obese mice.
Dr Jin’s work will provide an incentive for human researchers to look at brown adipose tissue and its modulation and enhancement as a way to control human obesity and diabetic epidemic in the future.
