Had a thought, would you ever consider adding like a 'health retreat' button that, for a lump sum (say like 10,000euros) slims you all the way back down after like a month? Liposuction also probably wouldn't be a bad idea? Having weight *loss* be very slow is definitely realistic, but it could be nice to just pay it all away, so you can gain again... (as it's difficult to stay skinny whilst fattening a feeder...)
Edit: It would also be nice to self-inflict the special chemical tubefeeding juice would be nice! Via autofeeder or otherwise.
