As a psychologist who has worked in college counseling centers I have extensive experience working with those struggling with various forms of eating disorders.  

A note on "food thoughts":

One of the more significant challenges for those struggling with eating disorders is confronting the developed negative relationship with food.  Moving away from the enjoyment of a food experience with friends, family, or cooking solo those struggling tend to shift the thought focus from the positive, enjoyable experience and define their food experience in terms of numbers (calories, weight) and/or as an aversive experience.  This shift of focus may dominate the relationship with food, become obsessive, and lead to avoiding enjoyable dining moments.

In treatment, the cognitive (thinking) work is a critical part of progress.  It takes a great deal of effort to redefine the relationship with food, recognize different triggers (thought patterns, emotions) that are associated with problematic eating behavior, and integrate pro-healthy coping strategies into one’s lifestyle. 

Some suggestions:

1. Think of the relationship with food as an experience rather than a battle with numbers.
2. Give yourself an opportunity to consider meaningful aspects of a food experience (the enjoyment of music playing, friendships and laughter).
3. Recognize that change takes time; avoid discontinuing new coping strategies after a slip or lapse. Give yourself a chance to evaluate the slip. 
4. Self-reflect: consider whether you are treating yourself well or engaging in self-punishment.
5. Recognize the self-critical voice; give yourself a chance to evaluate those self-critical statements and labels.  Work on reframing “rethinking” those statements.

Be well!
