Earlier quoted context omitted.
The number of "Obese People" far outweighs the number of chronic alcoholics... we are talking about almost 1/3rd of the population being obese (i.e. not just a bit fat, or chubby, just straight out obese).
Sugar isn't the cause of obesity though. I think people that try to blame it all on sugar are simply looking for a scapegoat. It's easier to actually over eat on fat than on sugar because of a higher caloric density. Carbs are just cheaper so they get added to everything as bulk.
Also let's not overlook how alcohol could contribute to obesity either.
