Rendering the obese

I saw a photo of an obscenely obese fellow in an article. The fat guy in this photo gives an idea of how to render a new troll. So grossly obese. I usually have this one obese art director, Jabba the Hutt (okay, not the real name), in mind when I render trolls. Now I got this new photo. The thing about grossly obese folks is that it is hard for one who is not obese to conceive how they can be with no necks, the proportions and so forth.
