Food addiction is real and just as harmful as other addictions like smoking and alcohol. But for some reason we still laugh about it like it doesn't exist. We even welcome with open arms new products that will try to make us addicted.
Next time you see a fat person, frame it as food addiction. You think they want to exist as a useless, grotesque blob? You think they don't know they have an embarrassing body and their oversized clothes don't really hide it? You think they are happy feeling uncomfortable and incapable all the time? They know it's the food, but they can't stop.
Next time you go out, start mentally replacing junk food with cigarettes. Replace the "golden arches" with Benson and Hedges. That waft of carefully engineered and pumped out Subway smell with cigarette smoke. The advertising, the vending machines, all of it. Then ask yourself why people are obese. It's an addiction with no escape.
