The really crazy thing that happened to me when I changed diet to a more gut-biome friendly* is that (like I craved sweets before) I started craving vegetables and oatmeal. Like there was a regime change in my gut and the new guys pushed the buttons to get more of their food.

(less/no simple sugars, much more vegetables and starches/fibers, regularly eating 4 corn/20 plant oatmeal few times a week)
