This research helps us understand that as long as the carbohydrates we eat are unrefined (and our guts are generally heathy), the amounts of macronutrients we consume may not matter. Conversely, if our guts are damaged and we are suffering from SIBO or related problems, a low-carbohydrate diet (which prunes back the microbiome) may be a smart treatment option, at least until we can fix the gut. Some people (like myself) seem to do better long term by keeping carbs on the low side (100 to 150g/day), while other people find they tolerate larger amounts of unrefined carbs.
