Have you ever seen those guys that have a huge stomach but at the same time where small pants? From behind they look like the average skinny guy, but when they turn around they look 6 months pregers. Usually these guys are middle aged and they have truely had a crap diet for most of their lives. By the way this condition is unique to western civilized nations. Eating processed foods daily Will lead to a build up of fecal matter within the intestinal wall. Over a period of time this dense rope-like substance will lead to a distension of the abdominal wall. 20-30 pounds of this substance would be unusual, however the average adult American carries about 7 lbs of waste.
