OT: I used to get that too until I switched to keto. I used to have tuna mayo sandwiches for lunch. Then I cut out the sandwich (I.e. bread) and just had tuna mayo and no longer got that after lunch low and stayed fuller for longer. It was quite amazing to me that I was fuller from eating less. You don't need to go full keto but try cutting out high GI carbs at lunch and see if it makes a difference.
