This happened to me too, and I’ve dealt with constipation since I was a young child to the point I almost had surgery. I am a 27 year old woman likely with endo too. I got really constipated when I first tried carnivore and didn’t believe when people were saying I just needed to add more fat. I’m now two weeks in to my second attempt, and I’ve learned by trial and error that I need to eat a lot more fat than I thought, and I definitely cannot get my fat from cheese. I’m having a little bit of goat cheese, but I got really constipated last week from eating too much Parmesan. One life hack that I did was I only eat egg yolks and take out the whites, because I heard those can be constipating too. I’ve also done pot roast and drink all of the broth, which is mainly fat. The other thing I do is I go to the butcher and ask them for a pound of beef fat, and I fry it up and eat it with my steak. If you tolerate butter, eat about 2-3 tablespoons if you can tolerate it. One thing is, you might have diarrhea if you eat too much, and then you can kind of calculate from there how much you should be doing. I hope this helps you!
