It seems like, when bulking, the general rule of thumb is to stay somewhere close to a 40/40/20 split. Why is this? What if I wanted to consume more calories but just can't stomach any more food? Assuming I'm getting plenty of complex carbs (420 grams), and I would like to get more cals, would it be okay to add 2-3 tbsp of EVOO or PB?? Would it be just as effective as far as adding mass goes?
By the way, I'm 5'9", 185lbs, 27yo, about 15%bf
