The underlying problem we're talking about is that people are seeing these unrealistic images of what a body should be, and are comparing themselves to that. I would argue that given what we know about how anchoring works, even if you tell someone that the image they're seeing is fake, the damage has already been done. Consider the Barbie doll; everyone knows that Barbie is a plastic doll and not a real person, yet there was a generation which grew up with that body being the goal.
