I also find that setting and declaring an intention is a powerful step to commitment and resolve.
Was just watching HBO Series "Weight of Nation" and while I was not thrilled with the consensus opinion that a person of same weight, age and gender of someone who has lost weight (vs. one who has always been ideal weight) meant the one who had achieved ideal weight by dieting had to eat 20% less to maintain. It affirmed to me that resolve to track and be mindful was the option I would continue.
Good for you and best of success to you!!
