To be fair, a lot of social problems can be fixed by more efficient patterns of distribution.
For the more specific case - a
lot of fast food is designed to be non-filling. After all, it lets them sell more stuff, which is a good decision

looks like you have more food (because hey, my plate is full!)
Really, it's kinda like the
Broken Windows Theory - you can attack the source indirectly by attacking the consequences.
