well parents like that would of put the idea in her head since she was a kid that there are "bad foods" that make you fat becuase it makes you "lose control", it would of been a way to explain away her own lazyness and now her kid grew up mentally ill believing she has no control. Yeah as an adult you are not being forced to eat too much, but the mother already mentally fucked her up making her think she has no control. These parents will tell their kids from a young age that mcdonalds is scientifically created to make you lose control and that the government hates them and wants to make them fat and sick.
