As far as the pooping goes, I noticed when I ate a more zero/low carb diet with mostly meat and eggs, even when they were cooked or raw, and even with a little fruit I didnt have a bowel movement at all. Then I ate a bunch of bean sprouts and had a bm in like 30 minutes, so I don't know what that was about. and the bm was soft and decently easy to pass, though not small. Another time I ate a bunch of fruit all at once and had a BM soonish afterwards. More recently I've been eating rather erratic, I went about a week eating mostly fruit and egg yolks, with only a little meat and fat thrown in, and I had BMs more frequently like that. those were soft and easy to pass.. sometimes even liquidy. however I did have a couple days that I ate SAD, eating pizza and frozen tv dinners, and I noticed after those days I tended to have smaller, harder stools that weren't as easy to pass. Right now though I've gone back to a more zero/low carb, eating mostly meat, fat, and eggs, though I'm hoping to add liver to my daily diet as well. I have not yet ever tried liver though, I don't know if I will even like it. But I've only just started back like this, so I don't know how my BMs are going to be like, but it seems like I don't have bms frequently when eating low/zero carb, raw or not. I also seem to have BMs whenever I consume large amounts of fiber, such as when eating a bunch of bean sprouts or eating a large amount of fruit, but small amounts of fruit don't seem to cause them.
I just figured I had some sort of super digestion that allowed me to completely absorb all the meat and eggs I was eating, whereas the only thing which wasn't absorbed was the fiber from veggies and fruit, lol, but I have no idea what's going on. I'm pretty sure when I first started, I went more than a week without a bowel movement.
