You can walk by the junk-food aisle in the store and not want anything
Okay, so maybe there is junk food in most aisles in the store - even the produce department - but you know what I mean. You can easily pass up the donuts, pop-tarts, chips, candy - all those things that exerted a siren call back in your dieting days.
When I dieted all those foods were 'off limits', so naturally they were what I wanted most. Now that I can have any food, any time, those foods are back in their proper place. Most of them I have no desire to eat. Those things I do still enjoy - like chocolate - I am much choosier about. And sometimes, I don't even feel like eating chocolate.
