Stuffing

Getting more "roundness"

I have a fairly average build so I'm more on the slim side. I can eat a lot of food and my belly noticeably swells up but it doesn't get that pronounced ball "pregnant" look that some people are able to achieve, rather it gets more and more convex spread throughout my lower torso. Is there a special way you can get a more pronounced gut or is it genetic? I'm talking about food stuffing here not enemas and what not, which I admit does make a pretty good looking belly but it's just not my thing.
I see a lot of the fatter people here end up with really round stomachs, do you guys use just food? How big of a difference is there pre-stuff and post-stuff?
