Gaining

1. Everyone is fat/obese and subsists on fatty, sugary food.

2. Everyone is morbidly obese and can barely walk, and most people have never even seen fresh food.

3. Humans have literally been reduced to immobile, vegetative globs of lard.

First one for size, although I prefer good food with the fat, personally.

Part of why I like the first one is that it still leaves room for being very fat compared to average . I like fat being normal, but I like those who really like being fat to have room to stand out, without it simply being a case of more immobile.

Just my taste.
