As said, it's really elementary. Not that it's a bad thing though.
Never really been a fan of Berardi though. Especially after he basically bribed everybody to leave positive reviews on Amazon and other places for his Scrawny to Brawny book. If anybody wrote something positive about the book and sent the link in an email Berardi would send them chapters of Precision Nutrition (this was before it was released).
Not that has anything to do with this topc or if Precision Nutrition is decent, but yea... I don't think you'll be disapointed with your purshase really. It DOES work (even though his reasoning behind some stuff is straight bull) and in the end that's what you're really after anyway. He does a decent job at reinforcing key points as well. Recipes always come in handy as well, and I remember his book had a whole "kitchen makeover" section. Telling you what you should/shouldn't have in your cupboards/fridge. Which you may find helpful.
