Gingerbread men weren't morbidly obese when I were a lass (in the 1970s). We shared him, of course.
I don't understand US food portions. I suppose the idea is that people support the economy by eating lots of food, and then they support it even more paying for the resulting treatment to lose the weight gained. In Japan the portions are all much smaller, which means that even if you go to a restaurant alone you can sample a pleasant variety of food for your meal, whereas in the US one is in danger of exploding before finishing half a portion. Because it is not necessary in Japan to pay someone to make you thin again, it makes sense economically that the food is much more expensive.
