you can do it right now through food. the gut microbiome tells the host what it wants to eat or not. Different diets cater to different bacteria, that's the reason (for example) that people that now eat healthy but before could eat as much junk food as they wanted without side effects can't simply "switch back" to their old habits without getting bloated or just plain sick. Anecdotal evidence: I lost about 50kg thru dieting, during my old days I could eat as much McDonalds as I wanted. Now if try to have anything but the smallest burger there I get sick, my system simply does not accept it anymore ;)
