http://www.thepaleodiet.com/ is the authoritative resource on the topic, but in my opinion it covers only one half of the puzzle. Still, many people who have debilitating diseases go from being deathly sick to above-average health when they follow the paleo diet.

Now, my own departure from the basic theory is that its not only *what* ancient hunter-gatherers ate that is important, but also *how* they ate. And how they ate was dictated by specific scenarios, hence the ‘cyclic’ in paleocyclic (its just a name that I thought would be descriptive). If you follow my posts you will notice that I try to avoid sticking to one macronutrient ratio or eating pattern. Since variety and nutrient cycling was a fact of life, our genomes are also adapted to expect that. Given that there were no fridges, protein powders or meal replacements, there were obviously times of lean and plenty, and the *types* of available food was also cyclic (as herds move, fruit trees bear, etc).

We should then:
1. try to eat *what* our ancestors ate (classes of food)
2. try to eat *how* they ate (variety, nutrient cycling and timing, intermittent fasting, etc)

I hope that helps…
