I don't think there will be negative repercussions. Usually they are just happy and kinda confused about finally being full. They still might not eat on their own next time, and they still might try to spit it out. But every *successful* assist seems to help stimulate appetite and gets them closer to actually hunting for their own food. The hunger and slow building of strength from eating does outweigh the trauma of having food stuffed forcibly into their mouths.
