Jim, with all due respect bro, I don't think, as a matter of fact I'm about 90% positive that much distension couldn't be caused by visceral fat on a bodybuilder with as low BF as these guys get, I think you would have to take a look at how they look before a carb load phase on how bad the distension was before. Again, I'm convinced that the combination of insulin, carb loading and stimulants all cause insulin sensitivity especially when carbs are low before loading.
If visceral fat was the cause, guys from the 50's through the mid 80's would have had distention since they carried more BF than they do today.
I understand what you are saying but consider this. The guys from the 50's 60's 70's and maybe early 80's (not so much) ate tons of protein and fats. Guys today are eating massive amounts of carbs in the form of rice, potatoes and yams, plus the dextrose they use with the insulin.
I have seen guys with huge guts and almost no visible fat on the outside of the stomach who have not used insulin BUT these guys are eating tons of carbs. No stimulants or insulin. Even though they are taking no exogenous insulin they are still over producing insulin via their own pancreas which is the same difference.
You think these guys below are taking insulin, GH, stimulants and IGF? of course not, they are eating tons of carbs and or drinking large amounts of beer and have been for years. They will eventually become type 2 diabetics. These guys have large amounts of visceral fat and because they do not diet like bber's it is even more pronounced, but maybe not as much as you would think.
Years ago I used to have guys carb up on insulin, but these same guys never used it in the off season and I never had anyone with a gut. Most were taking clen and ECA stack and some weren't. Bber's never had a visceral fat problem until they started to use insulin in the off season. I do agree that t he massive amounts of food certainly does not help matters, but trust me when I tell you that it takes months for this type of fat to go away and I am not so sure that it is reversable with everyone. Also consider the fact that once they have had this problem it most likely will return quicker and easier just like with muscle memory.
