[Ant-Man] If Ant-Man shrinks himself and gorges on cake crumbs until he can't eat anymore, when he reverts back will his blood sugar levels stay spiked or be normal?

Presumably, any food inside Ant-Man changes size along with him. Otherwise, he would explode if he were to shrink after eating a full meal

So we can assume that when he reverts to normal size in your scenario, the cake crumbs, digested or otherwise, would grow proportionately. His blood sugar levels should be the same as they were when he was small.
