I have (mostly) completely divorced emotions from this weight loss process and healthy lifestyle.

My commitment is nothing that I feel. It just is. On days when I don't want to exercise, or days when I do want to eat off plan, I remind myself that I am making choices today that will affect me for the rest of my life, and I need to make the best choices possible.

Emotions are treacherous things. They led me to bingeing and other kinds of emotional eating. When it comes to nutrition and health, they are rarely to be trusted. :)

I've adapted a lot of this from the CBT principles of the Dr. Judith Beck in her books, and 97.5% of the time it works. When faced with something I know I should (or shouldn't) do and my own unwillingness, I tell myself, "No choice." I don't have a choice about brushing my teeth or going to work or paying my taxes, and I don't give myself a choice about diet and exercise, either.
