I’m sorry but was this article stating that from a physicist’s point of view that cold or heat does not affect the body’s metabolism? The quote seems to sound like it’s ridiculous to think that wearing a sweater will cause you to burn less calorie, but if it helps keep you warm them it most certainly does. You’ve spoken in the past of uncoupling proteins and one of their main jobs is to heat the body (mainly UCP-1). Clearly being cold causes you to increase metabolism.

If you want any real world examples look at Michael Phelps who consume 10,000 calories a day and maintains his weight. If you do the math you’ll realize it’s impossible for him to burn that many calories through activity or normal metabolism. The fact of the matter is that the 4 hours he spends training all take place in water, which is highly thermoconductive. The same can be seen for people who climb Everest. They have trouble maintaining body weight and end up losing weight far faster than their activity and intake would dictate. It’s due to the cold.

There are plenty of real world examples of people using cold to more than double their weight loss. Hell the entire purpose of brown adipose tissue is solely to produce heat (and yes, research is showing is does exist in adults).

Sorry if I misunderstood this article and you agree with me, but from the sound of it I’m pretty sure you don’t agree. I’d like to hear your thoughts on it though.

I have a couple comments – first Bray cited himself numerous times – check the end of his review, I’m not anal enough to count them, but could only snicker when I noticed.

And “bray” is a noise …. er..donkeys make….

Dr. Eades – thank you so much for your tireless work and wisdom – you’ve helped me enormously.

2) Critical evaluation is a necessary part of science.
