I'm one of those dudes with jacked up metabolism. Two weeks ago I started a bulking program, I'm eating 2x the food I normally eat. But I'm also lifting very heavy weights at the gym so most of my gains are muscle. You can't avoid getting a little fat when bulking and going for mass, but you can minimize them so you can easily burn them off once you start the cutting cycle.
For example, I used to have a six-pack but now after just a few weeks bulking, I no longer have a six-pack but I'm noticeably larger than before so I think it's worth it. If your goal is to gain mass, you should accept the fact that you will put on some fat too as it's part of the program.
45 lbs ra jud ka brod? Are you sure you don't mean kg? That's less than 1/4 my weight and I'm 5'9"... What's your height/age?
