More Thoughts on Cold Training: Biology Chimes In
Now that the concept of cold training for cold adaptation and fat loss has received scientific support, I've been thinking more about how to apply it. A number of people have been practicing cold training for a long time, using various methods, most of which haven't been scientifically validated. That doesn't mean the methods don't work (some of them probably do), but I don't know how far we can generalize individual results prior to seeing controlled studies. The studies that were published two weeks ago used prolonged, mild cold exposure (60-63 F air) to achieve cold adaptation and fat loss ( 1 , 2 ). We still don't know whether or not we would see the same outcome from short, intense cold exposure such as a cold shower or brief cold water plunge. Also, the fat loss that occurred was modest (5%), and the subjects started off lean rather than overweight. Normally, overweight people lose more fat than lean people given the same fat loss intervention, but t...
