I'm off on a tangent for a bit.
What we think is not important, it is what we do as a result of our beliefs that is important.
This implies that a philosophy is equivalent to a spiritual approach to the weight problem. Watching our ideas, our impressions and living a delay tape in our head are equal concepts.
Some things are up to us and some things are not. So we can divide all internal issues into three groups, what we have control over, what we have influence over, and that which is beyond control or influence. Externally, we can influence a few things, and control nothing. We are responsible for our opinions, desires, impulse and aversions. Some will argue that we have no control over some of these, but some translations of Epictetus say responsibility, not control. We are responsible for our actions for sure. Desires and impulses can be redirected, where the control is poor.
So we can redirect the desire for additional food. We have a choice: live in the addiction/compulsion or live in recovery.
