Some fascinating reads concerning fat and our human experience over at the Big Fat Carnival. Particularly instructive: the section on Our Fat-Hating Culture.
If you're interested in this subject area, I also recommend Fat Politics by J. Eric Oliver. I haven't quite finished my copy yet, but it's a point of view with which I find myself in agreement.
It disturbs me when I see, on a regular basis, so much raw HATRED and derision projected about body fat. Overt, subtle, by people with relatively low body fat levels, by people with high body fat levels, at others, at themselves. It's ugly and poisonous and doesn't make anyone healthier in body or spirit or help anyone feel better. Unless, perhaps, it offers one that smug sense of superiority over people with higher body fat levels . . . right?
