Diets have improved where they have and not necessarily in the ways after the semicolon. The diets followed by 300+ pound people are unlikely to be healthy. Also, a lot of “light” foods are about as light as my laptop’s (black) keyboard; they substitute one source of calories for another but they’re not either less caloric or healthier with regards to other nutrients than the equivalent non-light food.

Are you trying to study whether faces change or whether people’s opinion of them changes? Those are two separate questions and cannot answered if considered together.

Yes, exactly, and the study **DSeid** linked to was studying how people’s opinion changes, and so of course they’re not controlling that away.
