Like a Can Opener in a Worm Factory

I think I sort of get where you're coming from. If the body isn't going to be the hourglass, then there is no point eating for that- but you can instead choose not to eat and have the *other* shape, the boy shape, that shows up everywhere.

The Boy does show up in a lot of places... but most often for perfume and other things that don't really involve having an actual body. The Hourglass shows up as soon as you need flesh to put things on- underwear, nice footwear, full lips for a proper pout. These do seem to be the only two bodyshapes available in media.

There's a lot you can do with clothing, though, instead of avoiding food. Clothing can make you look thinner or fatter, flatter or curvier, good posture helps massively with having/not having a stomach. Are you be able to try actively spotting the times you're slipping into the foodless habits and instead deliberately change your look with clothing and posture instead?
