Lot better way to fix your gut than play with poop.
Make yourself a batch of old fashioned sourkraut using organic cabbage and sea salt. When starting fermentation, cover jar with flour sack cloth for 12 hours, then put on the normal fermentation lock. Eat in 4 weeks with sour cream mixed in as a dip for chips. I will be chock full of natural and local pro biotics. It captures them through the cloth filter, and the acidophilus sorts them out for you.
Eat that every couple of says for a few weeks and you will start to loose carb addiction and belly fat.
Heck with that. I make my own Kimchee. That's the uber powerful health food.
There is also a "quick Kimchee" made of green cabbage rather than napa cabbage. It's fair, not really "Kimchee" IMO. Pretty good if you stir fry it with some diced pork or chicken.
That’s what the Romans used to feed their military.
