Indigestion and weird digestion problems are typical hypoglycemic symptoms. They will come and go. I never had them until I started the diet, and they came on when I did. I'm not sure why, but I can tell you it's a sign things are starting to change for the better in your body. It's almost like the digestive system is rejecting the diet because it doesn't want to have to work for its sugar, or, as I think, perhaps the brain is shutting down part of its digestive control like it does with other parts when it's evening out sugar levels as they drop. Not sure, but it's a typical symptom and most likely has absolutely nothing to do with intolerance. If you want to check intolerances, you have to at least use the structure of my diet, not eating the same thing for four days, that way you can clearly track what happens based on the type of food you eat. It takes awhile, but if you have any intolerances you'll find them this way. If you don't eat the same thing for four days, you'll figure it out, but if you do, you'll figure out nothing. You always have to be consistent with this, no messing around otherwise you'll never get anywhere. So yes, it is related to eating in the sense that this is very new for your body, I sincerely doubt you have a food intolerance. They're quite rare, despite opinions about it, and there are usually a number of other physical symptoms that you don't mention and the sensations don't just come and go, they're consistent. Like everything else that doesn't deal with hypoglycemia. This is a rule of thumb, hypoglycemic symptoms fluctuate. Why they do what they do i'm not sure of most of the time, some are clear, others, like the weird digestive bloating I hear about frequently, seems to have no direct relation, but it's just because we don't understand it entirely.
