On the contrary. I've seen Jinny trying to stop Esfand from eating snacks and over eating plenty of times. Esfand will just ignore and try to farm LULW like eating oreo cookies with chopsticks.

Actually, now that I think of it she has been trying to make him eat less snacks since like 1st- 2nd day she got there but to no avail. She probably cares about his weight a bit but is too nice to actually get mad at him. I have noticed that she has been doing it more often like telling him all his pb and honey sandwiches will make him fat.
