Yeah its very possible. But I have weighed myself pretty much everyday for the last 4 months and my gains have been pretty consistent and normal for the most part. I am 5'10" and once I hit 200 lbs I am going to cut down on my intake a bit. I dont mind being a bit big and a bit less cut (that doesnt mean chubby, just not super lean) since I am training for football. I did some calorie intake calculations before starting my "diet", I just dont go hard core into the preparation and food journal thing. I estimate, but I estimate with some research and knowledge behind it. Calorie tracking would still probably be better its just hard to do as a college student.
