A common expression is that we're "going on a Diet." The phrase suggests that, like a vacation trip, there is a beginning and an end. We dream of the day we will reach our weight goal and how wonderful it will be when we don't have to lead a life of painful deprivation. In the back of our minds, there is a comforting little tape playing, promising us that when our weight loss campaign is over, we'll be able to stop counting calories, carbohydrates, or fats. We long for the day when we no longer have to clench our teeth as we refuse a favorite dish that always causes us to salivate in our sleep. We reach for the carrot and celery sticks without anticipation or enthusiasm while torturing ourselves with visions of the special treats we'll enjoy when the diet is over.
