So I have a birthday coming up and have been asked for ideas as I'm an akward bugger to buy for

Seeing as I have got all my info on paleo off the interweb I though an actual book would be nice.

So what is the best book out there for really geeking out on the science stuff, I want to lean more stuff about anti-nutrients and insulin sensitivity/resistance, how different carbs are metabolised, how fat is used for energy with propper chemistry stuff, all that kinda crap
