Vanessa physically does not have enough fat cells to get chubby, and so she unintentionally destroys her body in other ways by indulging in quite a bit of junk food, and sweets, because she thinks it won't hurt her, even though it does. When vanessa eats healthy, either Charlie, or glitchtrap is in control, the latter being because he'd rather not have his vessel spontaneously die due to being unhealthy.
oooo, this is really interesting!
i’m taking a Nutrition and Diet Therapy class in college so i actually know Some stuff about this! if i was paying attention correctly, i think it’s because of genetics and also metabolism? sometimes both. some people just have a Really Hard Time gaining weight. i know sometimes bodies also just. don’t absorb calories.
so Vanessa is just out here indulging in Every Food Ever without really thinking anything of it. and i love how even Glitchtrap is like “you dumb bitch, get out of the way, you’re eating some fucking cabbage you goddamn garbage disposal”
