OK, my favorite book on nutrition is BodyOpus and that Ketogenic book by Lyle McDonald. Both give excellent breakdowns on the macro nutrients, whether u want to follow a keto diet or not. My favorite diet for fat loss is obviously a keto type diet, and for mass its just eat right foods (lots of clean lean protein, fruits, vegetables, dairy, complex carbs, and some good fats), but lots of them. For fat loss the 2 best routines I used I was the German Volume Training, and the 20 rep squat routine. For Mass my favorite routines are the 20 rep squat routine, and any other routine that centers around compound movements (cleans, high pulls, squats, standing presses, bent over barbell rows). My favorite exercise books:Super squats by randall Strossen and Dinosaur Training by Brooks Kubik (his videos alos kick ass!!!), and my favorite life/phiolosophy book:The Bible!!!
