Well, while preparing to teach Nutrition III at National College of Natural Medicine (NCNM) in Portland, OR; I have been compiling information about blood sugar regulation and…. naturally, insulin. Insulin is a hormone that many of you have heard/read about in relation to diabetes and blood sugar regulation. Those who are in the body-building and/or weight lifting industry have heard about it because of some of insulin’s anabolic (muscle building) properties. What does insulin do?

I’ve been working on a new project and came across an interesting research paper. Here’s another great reason to be lean (like you needed one); a 2009 article in the New England Journal of Medicine studied lean and obese men and the effects cold has on activating their brown adipose tissue. Brown adipose tissue, or brown fat, gets its color from the increased number of mitochondria compared to regular (yellow) adipose tissue. Mitochondria are the powerhouses inside our cells and can utilize fat for energy. With more of them, brown adipose cells can actually burn fat as it “spills” out of the adipose cells. Regular adipose cells need other cells’ mitochondria to burn fat that is liberated from them.
Classical thought was that brown adipose tissue serves an important role in infants but disappears in adults. Modern research is showing that adult men (especially non-obese adult men) still have brown fat and exposure to cold can activate it, allowing it to burn fat and produce heat. Interestingly, cold exposure can also activate the hypothalamic-pituitary-thyroid axis; this can help to bring a sluggish thyroid gland “back online”.
