So before you make the obvious (but erroneous) argument that "food is essential but alcohol is optional", consider that a majority of the food obese people eat are equally (if not more) "optional" and toxic to the body than alcohol. In fact, sugar is perhaps the worst thing you can put in your body. That's among the slew of other preservatives, additives, and other manmade substances obese people (and quite frankly, we all) eat (from time to time). Not to mention the absolute over-intake of calories we tend to injest.
So paralleling from certain "detox" and "cleansing" regimens that alcoholics go through in rehab programs..
The possible action(s)-
`1. take away food from clincally obese people. or people we just think are too fat. allow them only unlimited quanitites of water, lemons, and 2 vitamins / day. (similar to what I allow my gf 2 days / week). could be family members, co-workers, doctors, or anyone that the fat person is associated with.
2. make unhealthy foods prohibitively expensive for people with obese BMIs.
The possible outcome(s) (assuming success)-
1. overall a better looking society. maybe we can be healthy and fit, like certain Eastern European countries. one that eshews whalewomen in favor of slender, tall, perfectly fucktastic specimens.
2. pharma companies would see market capitalizations cut in half. short XLV and IBB.
The possible pushback-
1. capitalism thrives on complacency, complicity, and (most of all) idle workers. Idle, as in, the ability to sit for long hours without the urge to get up and go hiking, kickboxing, etc (i.e. non ADHD). If you've read books on human evolution, neurotriggers, and/or the rise of agriculture, you'd know that a hungry organism is a restless organism. Food is (too) plentiful, cheap, and abundant precisely to placate the masses into subversion and (the aforementioned) idleness. Your employer (and it's shareholders) don't care if you're obese, diabetic, and will die a painful death at age 50. They want ROI. Feed them 800 calories for $1.5 USD.
So alas, capitalism and the societal structure is the reason why we will never (perhaps ever) stop giving fat people food. It will cause undue anxiety, restlessness, and (eventually) the chaotic breakdown of the system due to rebellion/uprising of the wage slave. And therein lies the twisted beauty of capitalism.
