There is a significant difference between the following two statements: 1) Cravings cannot be used to determine what your body needs with 100% accuracy because some of them might be caused by gut microbes. 2) Cravings should still be taken into account because most probably only a small percentage will come from cravings. I understood you were referring to the first in your previous comment, so apologies if that was not the case. Either way, the only research that I know of pertaining to this topic is that some yeast (IIRC candida) can trigger carbohydrate cravings. That is something you should probably never listen to, even if they are physiological. Note that I have a strong bias here as I adhere to a no-fiber ketogenic diet.
