But it's not body shaming if you're not fat! /s Fats tell skinny people to eat burgers all the time. I'm sure someone in Maggie's position already feels insecure as it is (no boobs whereas her peers might have started getting them). I know my best friend was insecure.  And thinking about food and exercise at that age is just healthy. Kids and teens should run around and do different kinds of activities. Makes for good habits when they're older.
