I can speak from experience on some of those lovely symptoms.
When I was doing my first 9 months of <20g of carbs and a 30-40% caloric deficit, I eventually dipped down low enough that I could cover it in a single meal. So I figured I'd give intermittent fasting a go.
Almost immediately I noticed a difference. What was once solid was no more... Almost like the first week or so of the diet where my gut was getting used to the new order of things.
After a bit of trial and error I figured out that it was the large amount of fat in a single sitting that was causing my distress. I'm guessing here, but perhaps it isn't possible to absorb it all before it makes it out the other end? In any case, I went back to 2 meals a day and all was well again.
