A diet of grain-free whole foods with carbohydrate from cellular tubers, leaves, and fruits may produce a gastrointestinal microbiota consistent with our evolutionary condition, potentially explaining the exceptional macronutrient-independent metabolic health of non-Westernized populations, and the apparent efficacy of the modern "Paleolithic" diet on satiety and metabolism.

Carbs are not all the same. Some are better at feeding gut bacteria than others. Inulin, guar gum and glucomannan are pretty good at supplying raw material for the gut to work with.

And no-one knows exactly what the best combination of gut bacteria is at this point. Some with good research are Lactobacillus reuteri and Saccharomyces boulardii (a good yeast).
