I have been gaining for about 2 months now and I'm 14. I'm 5'10" at 150 Lbs. (I know skinny bitch) Anyways my metabolism is wicked fast ( I eat around 4k Cals) and I still am hungry. The funny thing is, even though I'm hungry, I still gain 1Lb.+ a week and am making tremendous strength gains.
Does this mean my body has a misaccuracy within my feelings of hunger or is my body just being very efficient and I should up the cals. to be optimal?
