Say “Hershey Bar” out loud, and experience what a Hershey Bar means to you. You’ll think about the taste, the consistency, the wrapper, licking chocolate off your fingers, etc. Now say “Hershey Bar” out loud again, and keep saying it out loud, again and again, for 1 minute. At the end of 1 minute, the words no longer have anywhere near the emotional impact. The words are more sound, than anything related to a chocolate bar. Do this with any carbohydrate food you are craving.
