Is the 12 step program for eating disorders similar to the 12 step program for alcoholics/drug users?

Mostly: They are similar in the recognition that one feels powerless over the addiction, that a higher power (understood as god, or the 12-step fellowship, or something else) is needed to help, and in working the "12 steps". Obviously one can abstain from alcohol or recreational drugs, but not from food, so there are important differences too.

Yes: The steps are largely the same. All 12 -step groups are based on the same steps. Admitting they were powerless over their illness/problem. And admitting that a power greater than themselves could restore them to sanity. Then following a series of steps to come to terms with their past actions and to enable them to lead fruitful productive lives and to be of service to others who suffered simil.

12-Step for Eating: It is similar, although it really should not be. 12-step eating disorder (ed) groups tend to preach abstinence from certain types of foods. However, research clearly shows avoiding specific foods or food groups leads one to overeat or binge on these foods, negatively impacts overall nutrition, and often leads to anxiety, depression, and eds.
