Thank you so much for your feedback. :)
The politics angle is definitely interesting & I could see that being a feature one day. Adding further weight stages beyond 'Enormous' isn't an immediate priority, but as you're the second person to request this now, I'm sure I'll add them at some point.
Along with player weight gain, a key part of the next major update will be mixing up the dates to make them much more varied and interesting, which will hopefully help with the flavour text element.
I'm really glad you're looking forward to player weight gain & how player immobility will work! I have lots of ideas for it & I can't wait to see what people think.
