The 12 Step program is modelled on black and white thinking - either you are abstaining, or you are engaging in your addiction. This works for substance abuse, as there is no safe amount of heroin, for example, to consume. But eating disorder recovery is about helping clients “find space in the grey”, and challenging black and white/all or nothing thinking. This rigid idea that promotes perfection is highly problematic psychologically, too. Your relationship with food will be nuanced, and organically changing day to day.
The abstinence model inadvertently promotes the idea that certain foods are the cause of binge eating disorder, or, conversely, if you just find the “perfect” way to eat, you will no longer binge.
