You're saying that the results of the experiment would be "obvious", so what's the reason for doing the experiment at all? If you're going to do the experiment, why do it with an alcoholic?
Far from being odd, his alcoholism was almost an ideal way to dismiss any concerns about fast food. Having a reasonably healthy non-alcoholic go to McDonald's when they are hungry, and still doing the gimmick of accepting "Super-sized" when offered, would be what you should do. The problem is that the effects of that wouldn't be very dramatic. McDonald's isn't a magical gypsy curse, it's rich, high-quality food with too much sugar (in the soda.) You can do the same thing to yourself cooking raw ingredients at home and drinking sweet tea. If you're an alcoholic, you can fuck up your liver without eating a thing.
