So I've read about a third of the book. I agree with others; love the fact everything is organized and flows in a logical fashion.

I did have one major question and maybe the book "answers" this beyond what I've read. He points to the outcome of the starvation experiments and also the caloric restrictions as proving to be bad for our metabolism as the body adjusts downward to the reduced calories. The net effect (for me at least) of a 23:1 fast, or even LCHF (for me, anyway) is calorie reduction. Most days that I've kept track, my total calories consumed are about 1400-1500, which is below the 1800 or so that he refers to as affecting people's metabolism (sorry, don't have a page reference handy). I literally cannot eat more. Is my metabolism doomed? Or, am I reading that the reduced calorie is only an issue if you are "hungry" and not eating? Am I missing or misinterpreting something?
