The biggest issue everyone struggles with, is not so much how to eat healthy, as how we relate to food and self care. We tend to label all foods as being good or bad, and then we judge ourselves and others according to how we eat. This is a set up for pain, especially when we remember every diet rule we have ever learned. This is a game we CANNOT win.
Instead of hating yourself or feeling superior, is it possible to simply observe yourself, without judging? In meditation we call this "dropping the storyline" and make an effort to notice the complex feelings that are occurring underneath it all. As Albert Einstein said, can you give up "trying to solve a problem with the same mind that created it?"
If you would like to learn more about this practice, I recommend you check out books by author and Zen Buddhist teacher Cheri Huber. My favorite book is "There's Nothing Wrong With You, Going Beyond Self Hate", which is written in hand script and includes drawings. If you prefer a more formal approach, try "How to Get Where You Are To Where You Want To Be". She has written numerous books, but most focus on compassionate self observation.
I will be giving lectures titled Mindful Eating on this topic in upcoming months around the San Francisco Bay Area. For announcements, sign up for my newsletter at www.eatbetterfeelbetter on the upper right hand corner.
