Adele Hite weighs in (pun intended) on AHS12:
Right now, “looking the paleo part” is important in the paleo community. … It is easier for you to become a valued member of a community if you look the part. Why? Because health, especially dietary health, is—for us middle class white people—a stand-in for character.
“Looking the part” demonstrates to the world that you are, indeed, a “responsible good eater.” If you are overweight, if you have obvious health deficits, if you are not white, if you are old—you stray from the community’s ideal of a “responsible good eater”—no matter what your diet actually is. Not “looking the part” tars you, however subtly, with the brush of “unhealthy other.”
