When you experience phantom fat, it is difficult for you mind to overcome all the years of negative reinforcement of your body-image. It's like phantom limb syndrome when people lose a limb but still feel it and even experience pain from the missing limb. You can fear that the weight loss won't be permanent and you will eventually regain the weight. Retraining your brain CAN take years.
