Interesting question. I think the phrase is a nice one personally, too often in society we shame people for not being the societal norm, particularly women. Fat shaming is seen as a safe thing to do, after all people who are seriously overweight are generally going to have health problems so there's the added frisson of pretending that it's all for their own good too. Win win.
Or not. We all need to learn to look beyond the outer packaging to the soul within.
