@faceiq are carbs optimal for gut healing

ive struggled with mild gut issues my whole life(bad breath, eczema, bloated face, infrequent stool) which i think is leaky gut and low stomach acid. I do believe a mix of fats and carbs is optimal but i know carbs can rot in the gut(and fiber is bad for gut) if my microbiome is healing. Is it better to do ketogenic diet with fermented dairy and meat or include fruits. ig just in general what diet is optimal for gut healing rather than sustaining health.
