I have SIBO. When my doctor and I discussed my diet, he told me that I eat way too much meat. He said that undigested meat will be consumed by my gut bacteria and by eating over 3 oz of meat per meal (I usually have 6-8 oz) I feed the bad bacteria in my small intestines.
I am quite skeptical since he did not even know about FODMAPS and advised me to eat seaweed (polysaccharides) and puffed wheat bran (!!!).
However, it actually made me think - what do those gut bacteria single-cell organisms feed on? I know about FODMAPS and starches, but do they eat meat too?
This would be unfair since I absolutely love grass-fed beef and eat it at least three times per week. And I have tried eating just 3 oz. It is impossible.

Some protozoa, H. Pylori, and other pathological bacteria eat whatever you eat, not just carbs. So no matter what you eat, if you have these, they are going to get fed anyway. However, 8oz meat is not really that much, it's a normal portion. Personally, overall, I eat about half a kilo (1.2 lb) of meat/fish/eggs daily.

I agree with the low starch approach. In my recipes, I limit the most difficult-to-digest carbs including fructose, lactose, resistant starch, fiber and sugar alcohols. Gut bacteria thrive on these carbs for most of their energy via fermentation. Fats aren't utilized well by bacteria in the absence of oxygen. And bacteria selectively take up amino acids for their own protein needs. But those carbs! They are the fuel for SIBO. Limiting carbs keeps gut bacteria in check. Under these conditions, the well adapted (healthy) bacteria will prevail.
So enjoy that grass fed beef!
