It does create pointless discomfort, but for many people it is a coping mechanism. Just like how some people don’t eat when they are sad or angry, some people eat too much when they are sad or angry. Or some people shop too much, take drugs, drink, have casual sex, etc. It’s just a way to make yourself numb and not have to think.

That being said…I really don’t think Britney looks like she overeats. Maybe she does, who knows, but she doesn’t look like it. At least not in these pictures.
