We have separate peanut butter jars at my house for reasons and one time my fat little sister saw me eating a spoonful (1 tablespoon bc I measure that shit) as a snack and she went and ate like 3 or 4 large spoonfuls. You know, because she "had to have some if I was!" And did I mention she had a rather large portion of triple chocolate cake about 30 minutes before? No? Well she did. She's only 13 and I tell her all the time to watch what she shoves down her throat but she doesn't care. My dad doesn't have the time to monitor her eating habits and when I try to she hides snacks everywhere. So no. They don't care about moderation, they're addicted.
