Im currently on an off season mass diet. Im gaining a fair amount of muscle but the fat im gaining with it seems to be more. I can understand that since im eating more. %40 carbs (mostly whole wheat...none of that refined stuff), %40 protein (lean protein), %10 fat (essential fats). But id like to regulate my fat gains. So i was wondering... How much fat is normally gained in a week on a mass program. What is considered normal? And how much lean muscle should i expect to gain every week for me to know whether im on the right track or not?
