Brown Fat Cold Exposure : ICEMAN Study Presented
Room temperatures proven to influence brown fat growth or loss
Today an exciting new study of the effect of room temperatures on brown fat cold exposure was presented in Chicago at a meeting of the International Society of Endocrinology.
“Our research points to a simple and practical brown fat activating and growing strategy in humans through temperature exposure modulation. We show that long-term minimal manipulation of overnight ambient temperature — well within the range found in climate-controlled buildings — was able to modulate brown fat activity in humans. Mild cold exposure stimulated brown fat activity while mild warm exposure suppressed it. Brown fat increase was accompanied by improvement in insulin sensitivity and energy burning rate after food,” said Paul Lee, MD, PhD, former research fellow at the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) of the National Institutes of Health (NIH).
Brown fat cold exposure with even small changes in room temperatures over the long term will have a beneficial health affect. Temperature changes directly effect the amount of brown fat and the activity of brown fat, which in turn has an important benefit on energy expenditure and metabolism in people. The study concluded that brown fat could be harnessed by simple ambient temperature adjustments making cooling an effective tool to combat obesity, diabetes and related disorders.
The flaw with this and other papers about brown fat cold exposure is that they ignore the practical limitations of people adjusting their thermostats down to sixty degrees. In northern climates during the cold months, this may be possible. But turning your air conditioning down in a home or business to the sixties is unaffordable and not very “green.” The solution may be in portable cooling. Brown fat activation with a cooling vest for weight loss and treatment of diabetes and other metabolic diseases will be a much more practical method, and has already been shown to work.
