That’s true for a certain percentage but misses part of the point here. Once an alcoholic has successfully detoxed, it is possible and highly encouraged that they do not partake any alcohol going forward.

That simply isn’t possible with obesity as humans require food to survive. So this is where the analogy with alcoholism breaks down as it is never possible for the obese person to be the equivalent of “sober.” Instead they have to learn moderation which is conceptually a different challenge than becoming a teetotaler.
