1) I had constipation on a very high fiber diet before starting carnivore. That was fixed in literally one day. It was the most dramatic change. Then it gradually came back after about 3.5 years.

2) beef, butter, chicken, pork, lamb, eggs, bacon, for > 95%. I do indulge in some processed meats with seasonings. Salt is the only seasoning I add, so I've become a salt snob and get the premium stuff.

After that unspicy diet, full strength kimchi is an experience.
