Well, the discussion about whether everybody is an addict who is fat, drags the attention from the question whether it is the case in general.

I would say the generation-wide on and off-dieting is showing the magnitude of the problem. What I personnally experienced is that fat people are in general in denial about (the cause of) being overweight, that's what triggered the resemblance with people drinking to much. Trying to convince other (fat) people to not take it not so serious, that their husbands don't mind, that it's not that a big problem etc. etc.

Now is being in denial not a thing that points to addiction persé, but in combination with a thing you enter above normal proportions in your body, it looks so to me.
