I wouldn't consider it a cheat but.....

I would say this is NOT A GOOD IDEA. You haven't overcome anything if this is what you will be doing. Thats like recommending an alcoholic to swish their favorite drink around their mouth and then spit it out.

Everyone needs to lose the mentality of cheat/not cheat... legal/illegal. Just make good food choices for the majority of your life. If you want a treat, have a treat. But keep in mind a treat is a treat because it is only once in a while. The occasionaly treat will not spell disaster. Doing stuff like taking a bite and then spitting it out is not sound dietary advice.
