I dont know how ill be feeling before every meal. What if i planned on making pot pie for dinner, but came home and was hungry right then and didnt want to wait or put in the effort for pot pie?

Or what if i packed left over chicken in my lunch the night before and turns out by the time lunch rolls around, i wanted a burrito?

Or what if people dont have an appetite due to their medication and can literally forget to eat because their body never told them they needed nutrients?
