There are at least eight diets commonly used for SIBO.
They all work on the same basic principle: reduce the carbohydrates that bacteria ferment into gas, and your symptoms go down.
Simple enough, right?
Except every single one of these diets still includes carbohydrates. They have to. You can't live on air. So each diet is essentially making its best educated guess about which carbs to keep and which to cut. And some of those guesses are brilliant for you, and some of them are dead wrong for you:,
The carbohydrates that trigger YOUR symptoms depends on:
your specific bacterial mix,
where those bacteria are camped out in your small intestine
how much damage they've done to your gut lining,
your enzyme status,
even the growing conditions of the vegetables on your plate.
One person's safe food is the next person's worst trigger.
I've seen it thousands of times, and it never stops being true.
So what actually happens is this: you pick a diet, you follow it faithfully, and you get some relief.
Maybe a lot of relief, maybe not enough.
And then you're stuck, because the diet says "eat this, avoid that," but your body is saying something completely different.
The real results, the 75 to 90 percent symptom reduction that SIBO specialists see across roughly 12,000 patients, those come when you stop following any single diet like a rigid rulebook and start customizing it to your own tolerances. That's the piece most people are missing. Not which diet is "the right one." They're all good starting points.
The piece that changes everything is learning how to identify YOUR specific triggers, expand YOUR safe foods, and build a way of eating that actually matches what's happening inside YOUR gut.
That's where the real freedom is.
