A New Perspective on Eating

I have just started on Food Rules and I am a little overwhelmed. I have always considered myself a "healthy" eater, but I am seriously rethinking that. Most of my diet consists of processed food. I eat either a lean pocket, lean cuisine, cereal, cereal bar, dannon yogurt, or canned soup for every meal. Sometimes my roomate cooks punjabi red beans or curried chick peas, but not usually. Most of the meals that I eat with real food I get at resturaunts, and I don't really know what they do to their food. I feel like I don't have time to prepare food and eat at a table. I usually just find something quick and eat at my computer.
