cash bet is that it does, because protein, bigger meals, build up the blood sugar levels, but they stay up for a lot longer, than eating...well, seem to recall, as a "kid" first or second year college, health science, possibly 101, back then, I was eating cereal in the morning, but the class showed the spike and rapid drop, in a graph, of blood sugar, and protein, went up slower, but stayed up longer, so I switched to oatmeal, boiled eggs, etc. in the morning, and sure enough didn't get "hangry" before lunch time...
