Hi Claire, I can totally relate to what you said about how class schedules and stress can affect eating patterns. My family also had family dinners. They definitely helped to structure my eating habits, and since I've been on my own, I have found that my own food cravings often are the result of poor meal planning on my part. I wonder how much of my cravings have to do with the bacteria in my stomach and how much has to do with the fact that I am just hungry. Perhaps it is a mix of both. Perhaps, the bacteria has to do with what we crave and the when is dependent on us.
