First off I know fat gain is inevitable in a bulk regardless of the macro split and I'm not worried about that, I'm just trying to understand the science behind having more fat in place of carbs.
Also, could anyone help to explain the pros/cons between having macros in excess or deficit? To better phrase this, what are the differences between having protein, fat, or carbs as your major source of caloric energy? Should I be basing the macro split on percentage of total calories or aim for a certain amount per lb of body weight.
Sorry for the barrage of questions I'm just having a difficult time settling on a routine diet for my bulk and heard the lower carb approach might be a nice switch.
