I am reading Primal Blueprint by Mark Sisson. His blog is "Mark's Daily Apple" in my links on your right. He offers 10 Primal Laws (because commandments have already been taken.) I'm familiar with a lot of it from having read about low carb over the years. The exercise information is of particular interest to me. His theory is that the "chronic cardio" offered as healthy is actually counter to sustained health and weight, in part due to elevated cortisol levels and appetite. This ties in with Gary Taubes, who bifurcates exercise from weight loss.
The first law is "Eat Lots of Plants and Animals".
