It's not really about discipline. If you're "starving" (low blood sugar), you eat big to stop that feeling. There's few people who can will themselves to suffer instead, and really why should they? Better to avoid the problem entirely in the first place. If you don't feel hungry (stable blood sugar) eating becomes a moot point/routine task.
