Fasting is a great way to break habits around necessity of food at certain times, or around what kind of food tastes "good".

On a shorter timescale, I also really like using mouthwash to prevent snacking. A well timed rinse leaves a nice minty flavor in my mouth and also somehow completely suppresses the urge to eat carbs.

Also antibiotics seem to work this way too, as they're essentially destroying a lot of the peanut gallery screaming for junk.
