Here is another recent study on Brown Fat (BAT). study
They used 16 deg C (around 60 degrees F) air temp to activate the BAT, so if you are against ice-cube baths, there may be hope for you!
We studied 24 healthy men — 10 who were lean (body-mass index [BMI] [the weight in kilograms divided by the square of the height in meters], <25) and 14 who were overweight or obese (BMI, ≥25) — under thermoneutral conditions (22°C) and during mild cold exposure (16°C). Putative brown-adipose-tissue activity was determined with the use of integrated 18F-fluorodeoxyglucose positron-emission tomography and computed tomography. Body composition and energy expenditure were measured with the use of dual-energy x-ray absorptiometry and indirect calorimetry.
Full Text of Methods...
Brown-adipose-tissue activity was observed in 23 of the 24 subjects (96%) during cold exposure but not under thermoneutral conditions. The activity was significantly lower in the overweight or obese subjects than in the lean subjects (P=0.007). BMI and percentage of body fat both had significant negative correlations with brown adipose tissue, whereas resting metabolic rate had a significant positive correlation.
Full Text of Results...
The percentage of young men with brown adipose tissue is high, but its activity is reduced in men who are overweight or obese. Brown adipose tissue may be metabolically important in men, and the fact that it is reduced yet present in most overweight or obese subjects may make it a target for the treatment of obesity.
Here's the thing: his writing can be difficult to decipher and grammar is NOT his forte, but those of us who interact with him on a regular basis here and on Facebook have gotten a lot more clarification on his views.
Yes, he's in your face, but he also encourages lab testing and experimentation. So, you can pretty much assume that you only have a faint surface understanding of his concepts unless you've really had some back and forth with the guy!
I see so many people criticizing (which is fine) and making assumptions based on outright misunderstanding/ignorance of his actual views (which is not fine). Case in point: I see people in the blogosphere calling him "very low carb" which is very inaccurate since he himself eats up to 300 gms of carbs around the Summer Solstice. They haven't bothered to ask him. Or, they take the Leptin Rx and assume it's a permanent way of eating.
His recent interview w/ Sean Croxton last week is a lot easier to understand than his writing is and he comes across a lot more gentle and laid-back than in his writing style (here it is if anyone wants to listen: Cold Thermogenesis with Dr. Jack Kruse 03/08 by Underground Wellness | Blog Talk Radio).
PS- those of us that "follow" him question him to no end. We drive him nuts with it. We experiment. There are a couple of points that I don't totally agree with him on. I don't just blindly believe everything he's saying. I do my outside research.
I see my fellow CT crazies as being a lot less brainwashed than, say, Matt Stone's followers, stuffing their faces with sugar and grains in order to "heal their metabolisms". To me that's so much more risky/dangerous than some old fashioned cold water, a few ice packs and traditional seasonal dietary cycling... this has a foundation in both history and science (and common sense!) It's truly not as complicated and high-tech as you seem to think it is.
