Not only are they looked down on, but for the first 3 panels (I don't really understand the fourth) these are things that society has decided to restrict and control. There are laws varying from outright criminalization to heavy taxes and restrictions on overserving. Being drunk in public can get you arrested. I mean imagine a world where junk food was heavily taxed, where waiters would cut you off from overeating, and you could be arrested for public overconsumption. Maybe being obese or supplying food to an obese person would get you time in jail and branded a criminal for life. If that happens, we can debate whether fat is being more harshly treated than these other vices.
