Wow, guys, thats completely not what bulking is about, you completely misunderstand it, i'm sorry.
And bulking depends on your aim, so there are two cathegories
Bodybuilders
Bulking : aim to build more muscle. The body only efficiently builds muscle(without steroid help) when you eat more calories then you burn.
They will calculate the calories they need to stay at their weight, in a 40%carb40%protein20%fat.
When they go on bulking, they'll simply add alot more carbs, for immense training, and because the body will enter the catabolic state alot less. as long as its burning carbs, or turning them into fat when you sleep, it will not touch muscles, apart for bcaa, and even that can be partially solved.
those "fats" will be olive oil, the fat in your meat,eggs for cholestrol(testosterone percursos) and alot of nuts. absolutely no butter or bad food, you want as few fat as possible.
after they bulked up, and build more muscle, they will then cut down to get the fat of. aim will be to have 1or lower% of fat, and keep more muscle then before you started bulking.
EVERY competitive bodybuilder will work in bulking and cutting
NO ONE will eat more then his 20%fat. you need fat for hormones and cell function, thats it.
