There are a myriad of things that could be considered. Advertising is used to make food sexy and appealing beyond its basic purpose of nutrition. It is also infinitely variable resulting in conversation. People often use it to control their state. The list is endless. As it is difficult to imagine that people would want to look physically unattractive or put themselves at risk, the simple task of not putting as much food in ones body is a not so easy task.
Another area is finance. One component to financial stability is not spending as much as you make. Again, it is a time tested formula. As simple as the idea of not spending more than one makes is, not many can manage it. The psychological traps that prevent many from doing something so simple are too numerous to list.
