As a food addict, I am questioning if this whole problem is not one of OCPD, just aimed at food. the more I explore OCPD, and it's treatment, the stoics, philosophy, the more it seems to be rolled into one brain problem, that has different symptoms and different objects of obsessive compulsive behaviours. When we take Jeffrey M Schwartz's 4 step, and overlay those onto the 12 steps, the 12 step program provides a subject for Schwartz 3 step.
It looks to me that Schwartz takes a harmful obsession-compulsion and turns that obsession onto some other target.
