If your bloating right after you eat and then you feel hungry 2 hours later sounds like bad bacterial overgrowth in your stomach. Bacteria produces more acids than yeast=cause you to be hungrier faster. Sometimes certain bacteria can produce stronger acids than others. The bloating can be caused from the excess ammonia. Testing might be necessary.
Yeast overgrowth will usually make you feel like your food is just sitting there and you will not feel hungry for a long time (slow fermentation).
Have you been tested for bad bacteria in the stomach? Ammonia levels?
Glutamine can cause bloating for some. Take it on empty stomach to see if it causes bloating or not.
Are you taking anything that would cause die-off? Die-off can cause some bloating.
