Probably my favorite live action movie based on a manga, Alita: Battle Angel depicts a deep and detailed post apocalyptic world.
In some occasions we see Alita eating actual food and seemingly enjoy it.
So my question is: Do cyborgs have the ability to make use of the energy they get from food and if so do they.. go to the toilet?
If you include the original source material of the manga, the answer is that yes, after the food is digested, it is excreted.
Although, at one point, Alita claims it's only to fuel her brain, presumably since the rest of her body uses the nuclear reactor.
There is also a non-canon omake strip, "Creation of Alita's Innards", which explores both a "glucose-only" option and the full experience. It does not make it clear which choice Ido made.
