When you are looking for treatments of diet addiction, the goal is to normalize your relationship with food. It isn't realistic to try to give up eating or to learn how to stick to a highly-restrictive diet. To get past a diet addiction, the real work involves changing one's attitude toward food.
A therapist can help with treatments of diet addiction by directing the client to examine their attitude toward food and eating. Writing down thoughts around food and what you decide to eat (and why you made that particular choice) can be helpful. This process helps the person with the diet addiction to determine which of their attitudes toward food are negative or inaccurate. Over time and with the help of the therapist, negative and incorrect attitudes towards food and eating can be replaced with more positive ones.
This type of cognitive therapy can be helpful in treatments of diet addiction. The approach is based on the client's rational thoughts, as opposed to delving into their childhood memories to find reasons for unhealthy relationships with food. It is much easier to make changes to the way you think about something than to dig deeper and change the way you feel. The journal entries are examined in a rational manner and evaluated. When you find thoughts that you determine are not rational surrounding food and the way you eat, the therapist will help you to replace the irrational thoughts with ones that make more sense.
Over time, you will change your attitude towards food and eating. You will learn that food is a fuel for your body and something you can enjoy without using it as a way to satisfy your emotional needs. The bingeing will stop and you can institute a more reasonable eating plan to get to (and maintain) a normal weight.
