I began breaking my longer (not intermittent) fasts with a little bit of watery keto food such as: cooked vegetables in blender, pasta sauce, mushrooms, carrots etc.
Because whenever i break a fast with liquids i end up spending half the day on the toilet.
I still drink some coconut or saltwater after having a little food, but the water when alone for some reason just messes up my bowels, makes everything coming out of me liquid and gas.
Answer
Very thin slices of meat, for a couple of days. Add salt on the second day and then refeed with electrolytes in a small glass of water on the second evening. Fully functional and efficient system on the third day.
I’m carnivore btw, I think it helps coming out of fasts dramatically
