If you’re not used to doing 24 hr fasts most things will give you diarrhea. I do OMAD routinely and I’m fine but when I do ADF no matter what I break my fast with gives me diarrhea lol (food-wise; If you’re really good and do broth then lightly add nutrient rich foods back in you may be fine)
Hope it helps!!
I always break my fast with a glass of water first, after a minute or two, I have 1 banana with 5 almonds, 2-3 walnuts and 2 dates simultaneously and nothing for the next half an hour and then have your meal. This is the best way to break your fast because the body needs good fat for quick energy.
Try to have some broth. Then maybe 20 minutes later do a small serving of Jerky or steak, some kind of low fat protein. Then an hour later do a light meal. I’ve had the best luck with this strategy. It’s annoying, but it seems to have worked for me. Your body will eventually get used to longer times between meals as long as you keep your meal times consistent.
If you are new to fasting, it was probably more the fat and the spice that caused the diarrhea, not the pH of the kimchi. Until your digestive tract adjusts to intermittent fasting, it can overreact when you break your fast and jump from being “asleep” to being overactive, causing diarrhea.
For the first couple of weeks of intermittent fasting, it can be useful to break the fast gently with something light, not too fatty, and not spicy. This wakes up your digestive tract a little more gradually. I found that green vegetables (cooked, or in a salad) were a good “starter” course that didn’t cause problems.
After a couple of weeks, it stopped mattering as much. Now I do OMAD every day and can break my fast with pretty much anything, no problem. But it took a little bit of time for my system to adjust.
