This isn't the first time these fringe ideas from paleonu made it to HN. As Lena pointed out this is a blog post on an article about a study that the paleonu author hasn't even read the abstract for. Meanwhile, there's a mountain of evidence supporting endurance training:
According to one 32,000 person study in the American Journal of Clinical Nutrition (1999), "fit persons with any combination of smoking, elevated blood pressure, or elevated cholesterol level had lower adjusted death rates than low-fit persons with none of these characteristics". The same study found that aerobic fitness had a far more important impact on longevity than obesity did. This was cited in Fantastic Voyage, Kurzweil and Grossman, Chapter 22.
Another 100,000+ person study found that men who ran two or more marathons per year were 41 percent less likely to suffer from high blood pressure, 32 percent less likely to have high cholesterol, and 87 percent less likely to be diabetic than non-marathoners. Those who ran only one marathon every two to five years also had significantly lower risk for these conditions than non-marathoners. http://www.medicalnewstoday.com/articles/140104.php
This is some really interesting stuff. I've been experimenting around a baseline paleo diet(which has been pretty amazing), and I started doing short 15-30min morning runs as a way to induce a mild "wake up" stress, but I might switch over to doing some body-weight resistance(push-ups, situps, squats) instead.
The article is about a small group of elite long distance runners. I don't think you can draw any meaningful conclusions about your short morning runs here.
And it is worth noting that this is a blog post about an article about a study. The author of the blog post has not even read the abstract of the study, let alone the study itself. The article on which the blog post is based says Note that this study was published as an abstract and presented at a conference. These data and conclusions should be considered preliminary until published in a peer-reviewed journal.
