Paul - it sounds to me like you are going about this with absolutely the right attitude. It helps that you are making yourself accountable to your friends and family (here and at home). I would say that you're already a success with this, just because you've confronted your fears, got up off the couch (in a manner of speaking ), and are actively working towards your goals. I think that alone puts you above a large (and unhealthy) segment of the population in this country. And you've already noticed how just dealing with a negative underlying issue frees up energy for other things. All power to you! I love nothing more than to see the people I care about taking good care of themselves. That is, after all, where our first commitment needs to be.
As for myself, all summer I did pretty well, biking to work as well as longer rides on the weekends, walking, and practicing qi gong. I've lost some of my momentum lately, and need to correct this. I'd say my diet is fair; I'm not super strict with myself, other than avoiding red meats and fatty, fried foods generally. I do have a weakness for cookies and dark chocolate. But my solution to that is to just not buy it at the grocery store, so that it's not right there in the house. Really, as in Lon's example, it's a matter of retraining yourself when it comes to food. I don't miss milk anymore either, and now overly salty foods just don't taste good to me. I used to drink a couple of Cokes everyday, now my drink of choice is green tea. Just look at it as making different choices, rather than denying yourself something you enjoy.
Keep up the great work.
