I think "big back" is just a term that sounds polite to mean "fat" passive-aggressively, and tbh u shouldnt have to feel like u need to restrict food especially if u crave something. That just means ur body is lacking certain minerals and vitamins, so yeh dw about it! Also i follow @adhd.dietitian and @adhd.nutritionist for how to eat well if u want to look at what they do (i might not have adhd but my autism has similar ways of operating like adhd)
