Answer 1

[Revise my English, please]
If you are going on a diet, a strict one, and you eat something you shouldn't, then you are: engañándote a tí mismo (fooling or kidding yourself). But in the same context of the diet in a phrase like yours I would say comer es hacer trampas (like breaking the rules or cheating in a game).

There are other uses for engañar as cheat on someone: engañar a alguien, serle infiel or ponerle los cuernos (the last one is very informal).
