I have the same problem and finally realized I can't eat any grains, psyllium, or soy. And, it doesn't matter if they are low carb as in low carb bread or low carb keto chips made with soy. These things make me bloat till I feel like I will explode PLUS it makes me hungry all day. And, don't forget that the sugar alcohols like malitol, etc can bloat you. Or, you may be lactose intolerant. Try giving up all grains, dairy, and sugar alcohols for several days. If you no longer have the problem then add back one thing at a time till you figure out the culprit.
