I think I've N=1'd living off meat long enough to know it's nearly perfect. Meat dissolves almost completely in the early digestive tract. On steak and eggs, I had perfect stools! But as for starch, I am almost a complete stranger to the ways!
I never believed the "meat rots in yer gut" line from the anti-meat crowd (I'm not saying KnifeGill is anti-meat). I'm convinced its all the artificial chemicals and plastics (that what I call it) in our assembly line food. Our stomach and intestines have digestive juices that would, given enough time, probably melt metal. Meat is no problem for it.
Since going Primal I have about 80% less gas and intestinal discomfort and my "farts" are not NEARLY as offensive as they used to be.
Steak, eggs, potatoes - fruits, nuts, berries and forage. Coconut milk and potent herbs and spices. Tea instead of coffee now and teeny amounts of kelp daily. Let's see how this does! Not really had dairy much, and gut seems better for it.
