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...
Reflections on the 2013 Ancestral Health Symposium

I just returned from the 2013 Ancestral Health Symposium in Atlanta. Despite a few challenges with the audio/visual setup, I think it went well. I arrived on Thursday evening, and so I missed a few talks that would have been interesting to attend, by Mel Konner, Nassim Taleb, Gad Saad, and Hamilton Stapell. Dr. Konner is one of the progenitors of the modern Paleo movement. Dr. Saad does interesting work on consummatory behavior, reward, and its possible evolutionary basis. Dr. Stapell is a historian with an interest in the modern Paleo movement. He got some heat for suggesting that the movement is unlikely to go truly mainstream, which I agree with. I had the opportunity to spend quite a bit of time with...

For those who are attending the Ancestral Health Symposium this year, my talk will be at 9:00 AM on Saturday. The title is "Insulin and Obesity: Reconciling Conflicting Evidence", and it will focus on the following two questions:Does elevated insulin cause obesity; does obesity cause elevated insulin; or both?Is there a unifying hypothesis that's able to explain all of the seemingly conflicting evidence cited by each side of the debate?I'll approach the matter in true scientific fashion: stating hypotheses, making rational predictions based on those hypotheses, and seeing how well the evidence matches the predictions. I'll explore the evidence in a way that has never been done before (to my knowledge), even on this blog.Why am...

This week's lucky "winner"... cola!Thirsty yet? Visual cues such as these are used to drive food/beverage seeking and consumption behavior, which are used to drive profits. How does this work? Once you've consumed a rewarding beverage enough times, particularly as a malleable child, your brain comes to associate everything about that beverage with the primary reward you obtained from it (calories, sugar, and caffeine). This is simply Pavlovian/classical conditioning*. Everything...
