Just tryin' to lead ya in the right direction hun, not attacking or anything I promise
You need to start somewhere .. if your cals are way to low right now, slowly increase them up to get to a good base diet ... not all at once so you feel like a cow & bloat up
.. like killa said, yes I PREFER 40.30.30 b/c I have had such success with that as MY BASE, and use it as the base to judge all other things ... right now .. my goals vary ...
Those foods listed, yes are the healthiest & best to eat, which is why they are stapled all over this site
... when adding size, yes, you increase your portions, more food the better etc... whether or not you want to do a clean bulk or dirty bulk is up to you but eating more cals nonetheless is a given to adding more mass ...
You need to keep the cals you do eat clean, least processing possible, and burn more cals than you are eating... that will be possible with a clean diet & decent training routine + your BMR .. no problem
Is this helping?
