Here is my look on it. First couple years I was doing a bulk each late fall/ through winter, I would eat everything in sight. Everything just shy of junk food, other than pizza. Yes I gained a lot of weight, I gained a lot of muscle and more fat than I wanted to. Burning all that fat off was a b!tch!
This year and a half I have really kept track of calories and eat super clean. I weigh as much as I ever have, and I am as lean as I have ever been. I just eat about 500 cals over maintanence a day...super clean.
So in review you can:
Eat a lot of whatever---> gain a lot of weight (muscle and fat)---> then run like a mo-fo to burn that fat off
OOORRR...take the time to count cals and eat clean above maintainence---> gain muscle, gain little to no fat, and in my case I lost fat!
