Yea, I was definitely more gassy than normal, although it wasn't terrible. It got a lot better as I did the diet longer, after that 2.5 week point it was almost gone.

Could be that I reduced my OJ/fruit consumption and had more energy drinks instead, too? Less fiber.

From what I understand, it's not just about fiber. Fructose is more difficult for the body to absorb than glucose, and any unabsorbed fructose will get fermented by bacteria in the colon, causing gas.

Over time the body can adapt by: (1) varying the bacterial composition of the colon to more efficiently ferment the excess fructose (thus reducing gas); or (2) upregulating the transport proteins in the small intestine that absorb the fructose. And apparently these compensatory processes could take weeks or months.

I see. I think I've heard some Peaters talk about the fructose/glucose ratios in some fruits for that. Maybe oranges are particularly bad? I'll say for me it wasn't that bad, just sort of what I remembered from eating SAD: multiple farts a day, lol.
