I've been only eating until satiation on an OMAD style like you have been going for and I found that when I eat too little a few days in a row, I become voracious for my next meal. It doesn't seem to hurt anything as long as I don't cheat with carbs.
Vegetable matter absolutely causes me to bloat. Just the gas it causes alone will do that if not any other reaction I have to it.
