My condition already makes me seem a freak to the pizza-loving masses, at least I can share the soda with them.

Emotional value of food? Oh yes indeed. We're talking about the same thing, but I'll describe it differently and hopefully dodge a turd-size argument.
The farmed meat/polluted produce example has two important twists that the coke comparison doesn't have. First, the human requirement for animal and plant food is high compared to the human requirement for soda, which is decidedly zero. Second, there is a cost difference between factory meat and grass-fed, hormone-free meat, and between pesticide produce and organic produce. The cost difference between coke and diet coke is zero. How would it change our argument if diet coke cost twice as much a regular coke?
It might change in a way that includes other costs, like the ones you outlined in your post above. To drink a regular coke and have it do something awful to you is a cost you have included in your purchase, making a diet coke much cheaper than a regular.
Emotional value of food? Oh yes indeed. We're talking about the same thing, but let's partition "emotional value" so it's a bit less vague, at least to me, into the social value of food and the neurochemical value of food.
You wrote of the social value of food, and being able to share food with friends. Very important, we'd agree. Sharing food gives us a fellow feeling, a sense of good that transcends the value of the food shared. With friends, it makes us feel bad to sit there and not share, expressing or implying that they're eating crap, and the crappiness of the food overcomes the desire for fellow feeling with people that you love. Offense taken by other people enters into our calculation whether or not to share, and offending friends makes us think twice, whereas offending strangers SHOULD roll off our backs.
And all this important calculation is done while under the influence of neurochemistry. Diet coke has the advantage of caffeine without the blood-sugar freakout of regular coke. In addition to being a stimulant, caffeine raises cortisol which raises blood sugar, which is always nice if your blood sugar is low after a long day of errands and suffering through Walmart. It's not a "treat" in the nutritional sense, but absolutely a treat in the neurochemical sense. You may also be getting thirsty as well, a neurochemical state that's almost impossible to resist fixing.
Then there's the real biggie: dopamine. The neurotransmitter of desire. Makes us feel oh so good. Want something? That's dopamine. Thirsty as hell on a hot summer day? The near-spiritual feeling of putting a cold glass of water up to your lips is your dopamine cranked on full blast.
We, as overweight people, usually have abnormally high serotonin, which gives us the opposite feeling as dopamine. Dopamine is the excitement we feel, and serotonin is the contentment we feel. It's no wonder that we are so inclined to cheat on our diets with our dopamine so low all the time. The dopamine rush we get when we open the lid of a box of doughnuts is a welcome change from swimming in serotonin all day. For those of us hooked on our own dopamine, it's the thrill of anticipation that captivates us neurochemically (emotionally).
This powerful stuff is our brain's way of telling us, "Now don't do anything stupid like think!" Don't do anything stupid like pull the glass of water away from your lips before taking a drink! Dopamine is there to override our more rational serotonin. Dopamine distracts our neocortex so that the mammalian, reptilian, survival part of our brain can take over and get its way.
After it's all over, dopamine disappears, and our neocortex resumes command to rationalize our behavior after the primal part of our brain has made our decision for us. Just like standing in line at the supermarket and making a bad impulse buy, posting to an internet forum is an immediate gratification that our rationalizing brains have to cover for in order to keep us sane, and only preferably right.
A diet soda at the pizza parlor is a brief calculation that (you're right, Wooo) no one should fret over, no matter which way it goes. To make fun of fat people and then try to justify it to total strangers requires heroic neurochemical effort.
