I suspect that the fat parents are forcing their children to be a miniature version of themselves. And that they won't accept if their kids have a "skinny body" AKA aren't flat moonlets. Also I really suspect some parents are so vain that they don't want their kids to suceed beyond themselves. Finally, some people, many people, become fat because it's an easy thing. Eating is good sure but they also gain the "no shame loser" status. Fat women are not judged if they are single/etc. When people become fat, they really do become subhuman, which puts them beyond a fair amount of gossip/social expectations. So they become fat to opt-out, giving up on life. And I think they are intent on opting-out their children from a decent/normal dating life as well. It is really disgusting.
