That's one of my concerns as well. When dealing with people exhibiting addictive behaviors, the typical approach in psychology and a lot of addiction groups is to get them to stop, or at the very least get them on some sort of substitution therapy (methadone for heroin addicts for example). Obviously, doctors would be in a lot of legal trouble for telling obeasts to stop eating, period, even if we may be better off in the long run. Maybe someone could make a fortune off of a sort of "food substitution therapy?" Methadone equivalent food for fatties? You know, maybe like that soylent green food mix, something engineered in such a way that you eat X amount of that, and only that, in order to maintain a certain weight.
